Breakout! [THINK WATER]



What if you had to walk a kilometre to get water to brush your teeth? What a nightmare! In some copuntries, people have to walk a total distance of 14, 000 km every year just to collect water. Find out how you can make a difference.

Water Wars - Think


Veronica Lake, a Michigan-based environmental activist, has noted that corporations acquire the world's water by three major methods: a) by "water mining" the underground aquifers, or deep sources of many of the world's streams or rivers; b) by leasing state and government water systems and collecting revenues; and c) by "managing" city water systems.

Water Wars


There is a difficulty when trying to deal with any problem on a global scale. one person can give a solution but two people will bring an argument. now multiply it.


everyone knows they should change but nobody will do it first and everyone wants to be last.

re: fossil fuels. i love the idea that the human race discovered fire for energy thousands of years ago and still haven't moved on.

Running For Water


Running For Water from polly green on Vimeo.


1 in 5 people suffer from the lack of safe drinking water. In 2007, 21 people ran over 15,000 miles on a non stop, 3 month, around the world running relay to help raise money and awareness for this life threatening issue.

Facing Water Crisis in Machhar Colony

Amar Guriro, a Karachi based journalist, and a WaterAid fellow, has named Machar Colony “The town of miracles”. As we walk through piles of rubbish surrounding children who use the streets as a playground, he explains that surviving here is only possible by the appearance of small miracles.




A major sewage drain passes through Karachi's largest slum settlement called Machar Colony, home to around 700.000 people of different nationalities including Afghans, Bangladeshis, Biharis and Burmese, among others.

As Machar Colony is an illegal slum settlement, government departments do not provide even the most basic facilities like gas, electricity or potable water. The open drain, blocked under a thick layer of garbage, is also the passageway for potable water supply pipes. Residents have managed to connect pipes to the main water pipeline across the main road beside the colony from where they can then distribute the water to underground storage tanks.

To get rid of the garbage all around, people often set it on fire and, often, the sewage water then mixes with the drinking water supply through the melted plastic pipes. Due to this situation, the majority of children of this colony suffer from viral infections, respiratory disorders and waterborne diseases.

MULTI-MEDIA WATER FILTERS


Multi-media filters represent a significant improvement over single-media filters. This is due primarily to improved filter bed action based on the innovative use and selection of filter media. Multi-media filtration permits delivery of high quality filtered water at much faster flow rates, as compared to a conventional sand filter.


In a conventional sand filter, lighter and finer sand particles are found at the top of the filter bed, and coarser, heavier sand particles remain at the bottom after backwashing. Filtration takes place in the top few inches of the filter bed.

The multi-media filter is radically different. The multi-media filter bed, in comparison to the sand filter bed, is upside down. Coarse, but lighter, particles backwash to the top, whereas finer, but heavier, particles remain at the bottom of the bed. The innovation lies in the selection of suitable media. This configuration has many advantages. The entire bed acts as a filter, rather than only the top few inches. Turbidity is trapped throughout the bed, enabling the filter to hold far more solids filtered from the water before backwashing is necessary.

Typically, the filter bed is made up of three layers of filter media. The total bed depth is about 26 to 40 inches. In a three layer filter the top layer is made up of large, lighter weight particles of anthracite coal and is from 15 to 18 inches in depth (particle size 1.0 to 1.5 millimeters, density 1.35 to 1.75). The middle layer contains from 8 to 15 inches of heavier and smaller particles of calcined aluminum silicate or sand (particle size 0.5 to 0.6 millimeters, density 2.65). The bottom layer contains from 3 to 6 inches of heavier garnet (particle size 0.2 to 0.3 millimeters, density 4.0 to 4.2). This semiprecious red silicate mineral is 50 to 60% heavier than sand.


A multi-media filter is backwashed in the same manner as a sand filter, using reverse or upward flow of water through the filter bed. The various layers of media retain their stratification because each material has a different density.

In a four-media filter a fourth or top layer contains from 3 to 6 inches of lighter and larger plastic pillows (particle size 2.0 to 4.0 millimeters, density 1.1 to 1.2). Their density is slightly above the density of water which is 1.0

Advantages

1. The multi-media filter can operate for much longer periods of time (five or more times as long at the same filtration rate), before backwashing is necessary because the bed can hold more turbidity. Turbidity is trapped and held throughout the entire bed depth, rather than the top one or two inches.

2. Multi-media filtration is much better suited for use in a closed pressure tank since cracking of the bed, and subsequent breakthrough of turbidity is virtually eliminated and the need for visual inspection is unnecessary.

The use of pressure tanks, rather than open basins or filters, is an obvious advantage for point-of-use iltration and could also be of real importance in the filtration of small community water supplies.

More rapid filtration flow rates in multi-media filtration allow the use of smaller diameter tanks with equal or better results.

3. A very high degree of clarity is achieved in the filtered water because of the fact that the finer particles of garnet at the bottom trap finer turbidity particles.

4. Another important advantage is that the multi-media filter can clarify water at a much higher flow rate than a single-media sand filter (5.5 to 8 gallons per minute, as compared to 1.5 to 2.5 gallons per minute in a 12 inch diameter tank). This is 14 to 15 gpm per square foot of bed area, as compared to 2 gpm per square foot of bed area. This is a very important difference in the production of filtered water.

Central Systems

In small community water supply filtration the conventional massive sedimentation tank, which allows larger particles of turbidity to settle, is replaced by the centrifugal separator which does the same job in 1 % of the space.

Centrifugal separators have been used in mining and mineral recovery for many years. Solid particles entering the separation chamber are acted on by high centrifugal forces which move the particles to the outer separator walls and then down to a collection device at the bottom. At the same time the clarified water moves toward the center of the separation chamber and upward to the clear water outlet at the top.

Separators can remove up to 98% of all suspended particles, down to a particle size as small as three thousandths of an inch (74 micrometers). A human hair has a thickness of about 100 micrometers.

In the multi-media filter the traditional feed of alum as a coagulant is reduced. At the same time it is supplemented with a polymer (polyelectrolyte) which forms a stronger floc and is applicable over a broader turbidity range.

Contact Clarification

A separate tank, called a contact clarifier, provides hydraulic contact flocculation and surface storage clarification. This replaces traditional paddle flocculation and four hours of quiescent clarification. The sand filter which followed in the traditional system has been replaced by a more efficient multi-media filter. Thus, without process shortcuts, process time has been reduced from the traditional 41/2-6 hours to 8 minutes!

Typical results for multi-media systems include reduction from 200 NTU to 0.42 NTU on a high turbidity water, and from 25 NTU to 0.15 NTU on a low turbidity water.

According to recent news and reports, most tap and well water in the U.S. are not safe for drinking due to heavy industrial and environmental pollution. Toxic bacteria, chemicals and heavy metals routinely penetrate and pollute our natural water sources making people sick while exposing them to long term health consequences such as liver damage, cancer and other serious conditions. We have reached the point where all sources of our drinking water, including municipal water systems, wells, lakes, rivers, and even glaciers, contain some level of contamination. Even some brands of bottled water have been found to contain high levels of contaminants in addition to plastics chemical leaching from the bottle.

Disease-causing organisms in drinking water


TASTE, ODOR, AND TURBIDITY


Regardless of any other factors, water piped into the home must be potable. To be potable it should be completely free of disease organisms. Water is the breeding ground for an almost unbelievably large variety of organisms. Water does not produce these organisms. It merely is an ideal medium in which they can grow. These organisms gain entry into water through a variety of sources. They enter water from natural sources, surface drainage, and sewage. Many of the organisms in water are harmless. In fact, they are extremely beneficial to man. Others have a mild nuisance value. And still others are a source of disease.

In general, those organisms which are potential disease-producers are of primary concern. These are of five types: (1) bacteria, (2) protozoa, (3) worms, (4) viruses, and (5) fungi. The presence of certain organisms of these various types can lead to such infectious diseases as typhoid fever, dysentery, cholera, jaundice, hepatitis, giardiasis, undulant fever and tularemia, as well as other diseases which spread through drinking unsafe water.

Tremendous strides have been made in the control of these diseases within recent years. Much of the credit must go to sanitary engineers for their careful, consistent control of public water supplies. As proof, outbreaks of typhoid fever in either this country or Canada are rare. Natural disasters can play havoc with water supplies, but under routine conditions typhoid is no longer a serious threat. Paradoxically, the freedom from typhoid and other similar water-borne diseases makes necessary even greater vigilance today. For now whole generations have grown up without the opportunity to develop a natural immunity to such diseases. Thus a failure in the protective system could result in far more people succumbing to the disease than in the past.

As was previously indicated, many water­borne organisms are extremely beneficial to man. Bacteria, protozoa and fungi that purify polluted water are essential to our well-being. Many of these organisms set into motion the chain reactions that result in purification.

We can classify living organisms in many ways and into many groups. Modern taxonomy categorizes living organisms into five kingdoms: Monera, Protista, Fungi, Plantae, and Animalia. Monera include single-celled bacteria and photosynthetic blue-green algae. They differ from all other organisms in that their more primitive cell structures lack a nuclear membrane as well as other membrane-bound organelles. They are called prokaryotes.

All other organisms are eukaryotes, that is organisms with cells that have distinct nuclei surrounded by nuclear membranes, as well as a variety of other well-defined membranous organelles. Organelles are specialized parts of cells (as mitochondria, chloroplasts, or endoplasmic reticulum) performing functions analogous to those of organs in many-celled plants and animals.

Members of the kingdom Protista are known as protists. They are solitary, single-celled eukaryotes (but some species form loose aggregations of cells called colonies). Animal-like protists are the protozoa; they are generally larger than bacteria and are mobile. Plant-like protists include several divisions of algae; these contain chlorophyll and carry on photosynthesis.

The Fungi are a diverse group of eukaryotes that are plant-like but that cannot carry on photosynthesis. They serve as decomposers, absorbing nutrients from dead leaves or other organic matter in soil and water. Fungi produce spores during the reproductive process. They consist of slime molds, such as the slimy masses found on decaying leaves and wood, and the true fungi, such as molds, yeasts, mildew, and mushrooms.

Plantae (plant) and Animalia (animal) kingdoms consist of the multicellular and well-developed plants and animals we are all familiar with. Plant cells contain photosynthetic pigments, such as chlorophyll, and plants carry out photosynthesis. Animal cells lack photosynthetic pigments, so animals must obtain nutrients by eating other organisms.

According to recent news and reports, most tap and well water in the U.S. are not safe for drinking due to heavy industrial and environmental pollution. Toxic bacteria, chemicals and heavy metals routinely penetrate and pollute our natural water sources making people sick while exposing them to long term health consequences such as liver damage, cancer and other serious conditions. We have reached the point where all sources of our drinking water, including municipal water systems, wells, lakes, rivers, and even glaciers, contain some level of contamination. Even some brands of bottled water have been found to contain high levels of contaminants in addition to plastics chemical leaching from the bottle.

Basic Types of Water Defined


In general, water for drinking and cooking should be wholesome. It should be both potable and palatable. It must be bacteriologically and chemically safe for drinking and be good tasting. It should be clear, colorless, and have no unpleasant taste or odor.


In our present-day world, we need at least three basic types of water of somewhat different quality, depending on the requirements of each use:

1. Utility Water. Water which is suitable for use in sanitation and lawn sprinkling; adequate in quantity, bacteriologically safe, but not necessarily treated to the highest quality.

2. Softened Water. Water which is optimum for bathing, shampooing, personal grooming, laundering and dishwashing. Since many of these uses demand hot water, fully softened water produces better results with minimum soap and detergent usage, and, in addition, provides conservation of energy required for water heating.

3. Drinking Water. Water to be used for drinking and cooking must be of high quality. It must meet or exceed the bacteriological and chemical requirements of both the EPA Interim Primary and Secondary Drinking Water Regulations. Since water used for drinking and cooking amounts to only about 1/2 of 1% of the total water supplied by a community, this amounts to 0.875 gallons per person per day of the 175 gallons per person per day furnished by the community. The remaining amount (over 174 gallons per person per day) is used for a variety of purposes such as sprinkling lawns and irrigation, flushing toilets, fighting fires, cleaning streets, as well as utility commercial and industrial uses within the community.

4. Of course, many commercial establishments (laundries, beauty salons, car washes, etc.), industries (for rinsing and specific processes), and institutions (hospitals, for example for laboratory use, hemodialysis, etc.) will want to provide extremely high quality water of different types for specific applications at the point of use.

Today, more than ever before, water is what we make it -not only for community water supplies, but also for individual water supplies. Point-of-use water treatment today is an extremely viable and readily available means by which water of extremely high quality can be provided. Moreover, since treatment takes place just before the water is used, point-of-use water treatment also provides distinct and unique advantages in that only the amount of water needed for each specific purpose or application is treated to the desired quality and also that there is virtually no opportunity for recontamination of the water from the distribution system after treatment.

Water Softening & Ion Exchange

Now when this calcium bicarbonate in solution flows through the exchange material in the softener, the chemical change which occurs is diagrammed below.


After a vast number of hardness ions in the water has become affixed to the softening material through the attraction of positive and negative charges, and most of the sodium ions have been released, the unit can no longer soften the water. It has become temporarily exhausted.

In actual practice, a small number of sodium ions remains on the softening material after the unit is exhausted. If no new chemical reaction is set into operation at this point, the incoming calcium bicarbonate ions flow untouched through the unit.

Just one of the ions causing hardness is shown for sake of clarity in diagramming. Actually, most water supplies contain a number of various hardness ions. The same process in each case applies equally in their removal from the water.

Water Entering Softner:

(1) The calcium ions in the water enter the ion exchange column. Here the waters pass through the bed of the softening material.

(2) The softening material consists of fixed irreplaceable anions. Affixed, that is, chemically bonded to them are mobile, replaceable cations of sodium.

(3) As the softening material anions have a greater affinity for the calcium ions than for sodium ions, it attracts them. In the process the calcium ions "knock" the sodium ions off the exchange material. As this continues, the exchange or softening material becomes loaded with calcium ions. Note that two sodium ions are released for each of the calcium ions absorbed by the softener.

Water Leaving Softner:

Water that contains calcium ions as it enters the softener will have a chemically equivalent amount of sodium ions in it on leaving the softener.

(4) After a certain prescribed amount of water has gone through the unit, the calcium ions will replace all but a small percentage of the sodium ions in the softener At this point, the softener is considered (Unit is now exhausted and requires regeneration).

(5) Now a rich brine solution is introduced into the softener by backwashing.

Note: to recharge a softener a concentrated solution of the regenerant (sodium chloride) is accumulated calcium ions free of the softening material.

(6) The calcium ions and excess brine solution are rinsed away.

(7) When this process is completed, the unit is again charged with sodium ions and is ready to continue the process of softening the water.

RECHARGING OR REGENERATION

Recharging or regeneration is necessary at this point. To do this a reverse ion exchange operation is now put into motion. In this reverse process, it is necessary to bombard the exchange material with the original type of cations in a concentrated solution. The affinity of the exchanger for the hardness ions is overcome by the use of a relatively strong solution of sodium ions. Generally, sodium chloride in a concentrated solution is used for this purpose. What occurs in all examples of ion exchange is a "swap" or balanced exchange of ions.

The calcium ions in the softening process are not destroyed. They have merely been replaced in the water by a chemically equivalent amount of sodium ions. The same type of balanced exchange occurs with whatever other hardness minerals that are removed from water.

Softened Water Energy Saving Study

In a recent University study energy consumption of gas and electric water heaters operated and tested on hard water supplies was measured and compared to measured energy consumption of gas and electric water heaters operated and tested on softened water supplies.


The gas heaters operated and tested on hard water consumed 29.57% more Btu's of energy than the gas heaters operated and tested on softened water for the same amount of energy delivered.

The electric heaters operated and tested on hard water consumed 21.68% more Btu's of energy than the electric water heaters operated and tested on softened water for the same amount of energy delivered.

It is not necessary to heat water to a high temperature to produce scale. Any increase above the original temperature of the water can cause lime scaling to occur.

Although no chemical reaction occurs which causes calcium sulfate to deposit when the water is heated, this hardness mineral is unusual as it is less soluble in hot water than in cold.

Hard water can also be troublesome in industry. In many industrial applications, however, not only must hardness be removed from the water, but all mineral content must be eliminated. Mineral deposits can cause serious difficulties in boilers, air conditioning systems, gasoline and diesel engine cooling systems.

Water is an excellent solvent. Our previous articles outlines how water collects the various contaminants found in it.

As moisture falls through the atmosphere, it absorbs amounts of carbon dioxide (CO2).It also collects amounts of this gas on and in the ground from decaying vegetation. Since carbon dioxide is a product of both combustion and decay it is present in practically all water supplies.

When carbon dioxide dissolves in water, some of it forms a weak acid called carbonic acid.

H20 + C02 --> H2C03

This acid is responsible for dissolving limestone or carbonate deposits in the earth. It also produces certain types of corrosion in water and steam lines. The natural solvent action of water is enhanced by carbonic acid making it even more effective in dissolving hardness minerals.


Hardness minerals-calcium and magnesium are in plentiful supply. While they are not found in their elemental form in the earth, they occur in combination with other elements in an abundance of forms. Common calcium minerals include chalk, limestone and marble. These substances are chiefly calcium carbonate (CaC03) or mixtures of calcium and magnesium carbonates and other impurities. Gypsum is calcium sulfate (CaSO4). In this compound calcium is combined with sulfur and oxygen.

Epsom salt is magnesium sulfate (MgS04).

Ions of the following calcium and magnesium compounds are found in water:

The amounts of these various chemical compounds present in water supplies depend on two factors:

1. The minerals present in the earth; and

2. Their solubility in water related to carbon dioxide (CO2) concentration.

On a decreasing scale of solubility, calcium chloride, magnesium chloride and magnesium sulfate are extremely soluble. They may be found in water in almost unlimited amounts. Calcium sulfate is less soluble. At the other end of the solubility scale are the calcium and magnesium carbonates which are very slightly soluble in pure water. The amounts of these last two compounds in water rarely exceeds two and five grains respectively. Calcium and magnesium carbonates are seldom found in natural water supplies because of their very low solubility.

While "insoluble" carbonates are rarely found, they are found in their extremely soluble form in hard water as calcium and magnesium bicarbonates. When water containing carbon dioxide comes into contact with calcium and magnesium carbonates in the ground, a chemical reaction takes place. The "insoluble" carbonate forms of magnesium and calcium are transformed into highly soluble bicarbonates. These are the principal hardness compounds found in water. It is interesting to note that these bicarbonate forms exist only in solution. If heat is applied to water, the bicarbonates can release carbon dioxide and revert to their carbonate or "insoluble" state. For this reason, bicarbonate hardness is often referred to as temporary hardness.

Hardness caused by the presence of the soluble chlorides and sulfates of calcium and magnesium are classified as "permanent" because these compounds cannot be removed from water through simple heating.

When these chemical compounds are dissolved in water, their ions are released

Why does hard water constitute a problem?

Actually hardness is a source of many problems. One important trouble area is the way hardness minerals react with soaps and detergents.


So important is this aspect of the hardness problem that hardness is sometimes defined as "the effect of certain elements which combine with soap to form an insoluble material known as curd."

The list of elements that possess this property of hardness include iron, copper and manganese, all present normally in relatively small quantities. More common, of course, are calcium and magnesium, which are usually present in significant amounts. Clothes washed in zero soft water are free of troublesome hard water soap curd.

For the homemaker water hardness makes home cleaning operations more difficult.

In the laundry, hard water leaves soap curd and detergent deposits on fabrics. This dulls colors and gives a grey or yellow appearance to white fabrics. Also hard water soap curd clings to fabric fibers, causing threads to become brittle and shortening the life of the material.

Hard water wastes soap and synthetic detergents.

Hard water leaves unsightly soap scum rings in the bathtub.

Hard water spots and streaks glassware and dishes.

Hard water builds up scale deposits in all water-using appliances, clogs hot water pipes.

Even more important to the homemaker and to her entire family hard water hampers good grooming efforts.

HARD WATER SCALE

Scale is one of the most serious problems caused by hardness mineral deposits. This particular by-product of water hardness puts many water-using appliances out of service. It clogs hot water pipes and can sharply reduce the heating efficiency of a boiler or water heater. When hard water is heated, scale is formed. This is due to (1) the breakdown of calcium and magnesium bicarbonates, (2) their reversion to the highly insoluble carbonate forms, (3) their precipitation from the water, and (4) their concentration on the interior surfaces of the water heater.

Under certain conditions the deposits form sludges. Both sludges and scale can lead to a sharp reduction in operating efficiency.

WATER PURIFICATION vs BASIC FILTRATION

With the growth of industry comes pollution. With pollution comes contaminated water.

Can the old basic filtration methods still create the best drinking water? Or, do we need more intense purification methods to combat the modern contaminants in our water supply?

The answer is probably the latter. But lets discuss what are the traditional filtration methods first. These basic traditional methods can include many options, with the two most prevalent being boiling and chemical. Although effective in ridding water of some things, we will show you that these methods still leaves behind harmful materials in the water.

Traditional Water Filtration Methods

1. Boiling

Historically, boiling is what has been used to disinfect water from microorganisms. In fact, when done correctly, it can kill most bacteria, but not all. Bacteria and protozoa are killed at the first bubble, and it takes about three minutes to kill the rest. The drawbacks to this method however are that first of all, it can require lots of fuel and cooking equipment. Secondly, water cannot be then used immediately, as it needs to cool down. Thirdly, since it is so hot, some of the water may evaporate before its use. Fourth, the water can still contain particles; so further filtering through a handkerchief could be necessary. Finally, boiling water does not eliminate chemical pollutants(including chlorine), poor taste of foul odors, and in fact can leave a stale taste. Boiling water may be the only method when camping, but in a household, there are more effective and efficient methods available.

2. Chemical

There are two primary chemicals used to purify water: iodine and chlorine. Both are lightweight, low cost and easy to use. Iodine has been proven effective in killing off viruses, bacteria and protozoa. However, the colder the water is, the more time it will take to purify with iodine. Iodine can also absorb into the dirt and debris naturally found in water, so the dosage will always vary. Also, pregnant women or those with thyroid conditions should not drink water with the chemical. Usually, iodine is just used for short-term purposes, and should not be used for more than three consecutive months. Many do not favor the taste it leaves behind either. The unfavorable taste can be combated by mixing the water with a sugar-based drink mix, or better yet, by not using the method at all.

Chlorine bleach is the second chemical purifier. The process of chlorination will cause dirt and debris to settle to the bottom of the water container and make the water visually clearer. The American Red Cross endorses the brand Chlorox. The Red Cross states that people should use an unscented household bleach that contains 5.25% sodium hypochlorite. When using bleach to purify, the recommendation is to add 16 drops of bleach per gallon of water, stir, and let stand for 30 minutes. If the water does not have a slight bleach odor, repeat the dosage and let stand another 15 minutes. There are many drawbacks to the chlorination method. If the household bleach is over six months old, it may not have enough potency to disinfect. Also, chlorine is very poisonous and adding too much can cause illness, internal organ damage or even death. Chlorine has been linked to many health problems, as can be read in the health section of this site. Also, if one decides to use bleach, be sure to add it at the time intended to use the water, not when storing.

Seeing the drawbacks of these traditional filtration methods brings us to why more advanced water purification may be required nowadays.

Advanced Modern Water Purification Methods

Water filtration by definition simply means to strain out the impurities from a water source. The larger the impurity particulate the easier it is to filter. The opposite is true also, the smaller the impurity particulate, the harder it is to remove. Thus, the size of the filter pore and the durability of the filtering element are important to the filter's longevity and ability to perform. Most filtering elements are made of ceramic, glass fiber, hard-block carbon, or materials that resemble compressed surgical paper.

Some of the better purification methods include the activated carbon and reverse osmosis. The best contribution that carbon makes to filtration is its ability to reduce chemical quantities, poor taste, odors and many pollutants. Because carbon is only mildly effective in filtering out particulates and microorganisms, it is mostly used as a second or third stage filter in home and portable water use. It is seldom used as a stand-alone filtering, and often times, used in conjunction with reverse osmosis. Reverse osmosis, which uses a semipermable membrane filter to separate the water from contaminants.

Reverse osmosis is highly effective in removing several impurities from water such as total dissolved solids, turbidity, asbestos, lead and other toxic heavy metals, radium, and many dissolved organic. The process will also remove chlorine, and also can remove nuclear radiation such as radioactive plutonium or strontium in the drinking water. Therefore, reverse osmosis combined with activated carbon seems to be the most advanced water purification method developed so far.

According to recent news and reports, most tap and well water in the U.S. are not safe for drinking due to heavy industrial and environmental pollution. Toxic bacteria, chemicals and heavy metals routinely penetrate and pollute our natural water sources making people sick while exposing them to long term health consequences such as liver damage, cancer and other serious conditions. We have reached the point where all sources of our drinking water, including municipal water systems, wells, lakes, rivers, and even glaciers, contain some level of contamination. Even some brands of bottled water have been found to contain high levels of contaminants in addition to plastics chemical leaching from the bottle.

A good water filtration system installed in your home is the only way to proactively monitor and ensure the quality and safety of your drinking water. Reverse osmosis water purification systems can remove 90-99% of all contaminants from city and well water to deliver healthy drinking water for you and your family.

WHAT ARE THE STANDARDS FOR SAFE DRINKING WATER

It is known that no one method of filtering or purifying water is going to eliminate 100% of elements from our drinking water. That said, water can be safe and acceptable, within reason. There are guidelines, set by the U.S. EPA, which measure water standards to make sure our water is safe.

'Acceptable' contamination levels of water are measured by two standards: maximum contaminant level (MCL) and maximum contaminant level goal (MCLG). For the list of induvidual contaminant standards, please click here.

The goal indicates the level of contaminant at or below which is considered safe for human consumption. However, given the size of most water systems, today's technological limitations, and the costs involved with water purification, it is impossible to provide the masses with water at or below goal level for all contaminants.

Because of these difficulties, the MCL standard was created as a compromise between public safety and feasibility, dictating levels that must be met before water is distributed to the public. This level is usually within 5% of acceptable contaminant range.

Post-Filtration Contaminants

Turbidity is a measure of the cloudiness of water, and an indication of filtration effectiveness. Cloudy water is a sign of the presence of microorganisms that can cause gastrointestinal illness. Although controlled at the original filtration source, soil runoff and other factors can affect turbidity levels by the time water reaches a faucet.

The pipelines that transport water from its original purification source to homes and businesses can affect certain contaminant levels. These include: vinyl chloride, known to increase the risk of cancer (goal level is 0; actual level is 0.02%); lead, which causes high blood pressure and kidney disease in adults and developmental delays in children (goal level is 0; actual level is 0.015 mg/L); copper, which contributes to gastrointestinal disease in the short-term and liver/kidney damage in the long-term (goal/actual level of 1.3 mg/L); and cadmium, known to cause kidney damage (goal/actual level of 0.005 mg/L).

Other factors can further contaminate water between its original purification and consumption. Fertilizer runoff and leaching from septic tanks can cause increased levels of nitrite (goal/actual level of 1 mg/L) and nitrate (goal/actual level of 10 mg/L), both of which are lethal to infants younger than six months. Water storage tank liners leak small amounts of benzoapyrene (goal level is 0; actual level is 0.0002 mg/L), which can cause reproductive complications and increased cancer risk.

The Effects of Disinfectants

Disinfectants to remove contaminants can also be harmful to humans in and of themselves. Use of disinfectants has led to the development of two additional water safety standards: maximum residual disinfectant level (MRDL) and maximum residual disinfectant level goal (MRDLG).

Just as with contaminant level standards, it is not always realistic to reach the residual disinfectant goal. In response, the MRDL offers a balance between human safety and available purification resources.

Disinfectants and their byproducts found in water include bromate, known to increase the risk of developing cancer (goal level is 0; actual level is 1%) and chlorite, which can cause nervous system damage in children as well as anemia (goal level is 0.8 mg/L; actual level is 1.0 mg/L).

Although there is a set standard for national water safety, individual standards may vary by state, county, and facility.

According to recent news and reports, most tap and well water in the U.S. are not safe for drinking due to heavy industrial and environmental pollution. Toxic bacteria, chemicals and heavy metals routinely penetrate and pollute our natural water sources making people sick while exposing them to long term health consequences such as liver damage, cancer and other serious conditions. We have reached the point where all sources of our drinking water, including municipal water systems, wells, lakes, rivers, and even glaciers, contain some level of contamination. Even some brands of bottled water have been found to contain high levels of contaminants in addition to plastics chemical leaching from the bottle.

A good water filtration system installed in your home is the only way to proactively monitor and ensure the quality and safety of your drinking water. Reverse osmosis water purification systems can remove 90-99% of all contaminants from city and well water to deliver healthy drinking water for you and your family.

Sources of Drinking Water

Sources Of Our Drinking Water



Water is a vital element in each of our lives. Not only is it essential to our health, but we also use it for numerous household tasks. Every day we use water for cooking, bathing, and cleaning, and drinking; but how often do we think about its source?



Where does our water come from? How is it treated? How do we know it is safe to drink? To answer these questions, it's important to go back to the basics. There are two main sources of water: surface water and groundwater. Surface Water is found in lakes, rivers, and reservoirs. Groundwater lies under the surface of the land, where it travels through and fills openings in the rocks. The rocks that store and transmit groundwater are called aquifers. Groundwater must be pumped from an aquifer to the earth's surface for use.

Consumers receive their water from one of two sources: a private well, or a community water system. A household well pumps groundwater for household use. The source of a community water system may be either surface water or groundwater.

Private Household Wells

Approximately 15 percent of the U.S. population relies on individually owned and operated sources of drinking water, such as wells, cisterns, and springs. The majority of household wells are found in rural areas.

Those who receive their water from a private well are solely responsible for the safety of the water. Private wells are not subject to federal regulations, and are generally regulated on a very limited basis by states. Local health departments may assist well owners with periodic testing for bacteria or nitrates, but the bulk of the responsibility for caring for the well falls on the well owner.

Since the well owner is primarily responsible for the water, it is important to know what poses a threat to the well and the groundwater which is its source. A variety of sources can cause well water to become contaminated.

Several contaminants occur in nature that may present a health risk if they are found in drinking water. They include bacteria, viruses, uranium, radium, nitrate, arsenic, chromium and fluoride. Many of these contaminants are naturally present in rock formations, and consequently end up in the water supply.

Other sources of contamination are a result of human activity such as manufacturing or agriculture, or individual misuse. The following activities may cause harmful chemicals to enter the well water owner's water supply.

Leakage from waste disposal, treatment, or storage sites.

Discharges from factories, industrial sites, or sewage treatment facilities.

Leaching from aerial or land application of pesticides and fertilizers on yards or fields.

Accidental chemical spills.

Leakage from underground storage tanks.

Improper disposal of household wastes such as cleaning fluids, paint, and motor oil.

Well owners generally disinfect or otherwise treat the water from their wells to remove the contaminants that are caused by such activities.

Community Water Systems

Approximately 85 percent of the U.S. population receives its water from community water systems. Community water systems are required to meet the standards set by the U.S. Environmental Protection Agency (EPA) under the authority of the Safe Drinking Water Act (SDWA).

The SDWA was passed by Congress in 1974 to establish nationally consistent drinking water standards. A standard is the maximum level of a substance that the EPA has deemed acceptable in drinking water. In 1986 the SDWA was amended to require the EPA to publish standards for 83 specific contaminants, and additional standards thereafter. To date, the EPA has issued or proposed limits for 87 substances. Community water systems are currently revising their drinking water programs to meet the more stringent requirements of the amendments.

Community water systems must ensure that the drinking water they supply does not have contaminant levels higher than the standards of the SDWA, the SDWA amendments, or state regulations.

In order to set a standard for a drinking water contaminant, the EPA first reviews the data concerning the health effects the substance may cause. The EPA then proposes nonmandatory Maximum Contaminant Level Goals (MCLGs). MCLGs are set at zero for contaminants that are known or probable human carcinogens. For noncarcinogens, MCLGs are set at a level where no adverse health effects would occur with a margin of safety.

At the same time, the EPA also proposes a Maximum Contaminant Level (MCL), the enforceable drinking water standard, which is set as close to the MCLG as possible, taking into account technological and economic considerations.

After a time for public comment and review of the MCL and MCLG, the EPA enacts a final regulation. States are expected to adopt the standard within 18 months of enactment.

The SDWA requires utilities to conduct routine monitoring and testing of public water supplies. Two types of sampling are required. Routine Sampling takes place on a regular basis and ensures that a treatment plant is running properly for delivering a consistent quality of drinking water. It also determines whether water quality meets the MCLs.

When a routine sample analysis indicates elevated levels of a particular contaminant that may exceed EPA or state standards, states may require systems to take a check sample. Check samples are used to confirm the results of a problem discovered during routine sampling.

In summary, the EPA generally delegates to the states the authority to enforce all federal drinking water standards. However; how well they are enforced is very questionable. (See the other news articles on some latest findings of our tap water). In addition, the national standards for contaminants were developed more than fifteen years ago by EPA. Today, there are many new industrial contaminants that was not even known to us back then. Plus, the standards for what is considered healthy and acceptable sure have changed.

Point of Use Water Filter Solutions

Whether consumers receive their water from a household well or a community water system, they may wish to treat it at its point-of-use (POU). Consumers do have the option to choose the higher quality of water that POU technologies can provide.

POU technologies treat water at single or multiple taps or for the whole house, and improve water quality in a variety of ways. Unusual taste, color, and odor or water may be corrected by POU technologies, and some POU devices also reduce harmful contaminants.

A variety of POU equipment is available for improving drinking water and other special purposes. Each technology is designed to solve one or several different water quality problems. In order to choose the right equipment, it is important to confirm the nature and extent of the problem.

The first step in correcting a water quality problem is often to have the water tested. When the safety of the water is in question, it should always be tested by a state-certified or other reputable laboratory. Testing for aesthetic concerns such as taste, odor, color, and hardness may be performed in the home by a professional water treatment dealer.

Testing the water will help determine the proper treatment necessary. We suggest you before purchasing a product, first become an educated consumer.

According to recent news and reports, most tap and well water in the U.S. are not safe for drinking due to heavy industrial and environmental pollution. Toxic bacteria, chemicals and heavy metals routinely penetrate and pollute our natural water sources making people sick while exposing them to long term health consequences such as liver damage, cancer and other serious conditions. We have reached the point where all sources of our drinking water, including municipal water systems, wells, lakes, rivers, and even glaciers, contain some level of contamination. Even some brands of bottled water have been found to contain high levels of contaminants in addition to plastics chemical leaching from the bottle.

A good water filtration system installed in your home is the only way to proactively monitor and ensure the quality and safety of your drinking water. Reverse osmosis water purification systems can remove 90-99% of all contaminants from city and well water to deliver healthy drinking water for you and your family.

Ultrafiltration (UF) is a variety of membrane filtration in which hydrostatic pressure forces a liquid against a semipermeable membrane. Suspended solids and solutes of high molecular weight are retained, while water and low molecular weight solutes pass through the membrane. This separation process is used in industry and research for purifying and concentrating macromolecular (103 - 106 Da) solutions, especially protein solutions. Ultrafiltration is not fundamentally different from reverse osmosis, microfiltration or nanofiltration, except in terms of the size of the molecules it retains.

A membrane or, more properly, a semipermeable membrane, is a thin layer of material capable of separating substances when a driving force is applied across the membrane. Once considered a viable technology only for desalination, membrane processes are increasingly employed for removal of bacteria and other microorganisms, particulate material, and natural organic material, which can impart color, tastes, and odors to the water and react with disinfectants to form disinfection byproducts (DBP). As advancements are made in membrane production and module design, capital and operating costs continue to decline. The pressure-driven membrane processes discussed in this fact sheet are microfiltration (MF), ultrafiltration (UF), nanofiltration (NF), and reverse osmosis (RO).

The primary advantages of low-pressure UF membrane processes compared with conventional clarification and disinfection (postchlorination) processes are:

• No need for chemicals (coagulants, flocculates, disinfectants, pH adjustment);

• Size-exclusion filtration as opposed to media depth filtration;

• Good and constant quality of the treated water in terms of particle and microbial removal;

• Process and plant compactness; and

• Simple automation.

Ultrafiltration (UF) is used to remove essentially all colloidal particles (0.01 to 1.0 microns) from water and some of the largest dissolved contaminants. The pore size in a UF membrane is mainly responsible for determining the type and size of contaminants removed. In general, membrane pores range in size from 0.005 to 0.1 micron. UF membrane manufacturers classify each UF product as having a specific molecular weight cutoff (MWC), which is a rough measurement of the size of contaminants removed by a given UF membrane. A 100,000 MWC UF membrane means that when water containing a given standard compound with a molecular weight of around 100,000 daltons is fed to the UF unit, nearly all of the compound will not pass through the membrane.

Substances with a molecular weight of 100,000 daltons have a size of about 0.05 microns to about 0.08 microns in diameter. UF membranes are used where essentially all colloidal particles (including most pathogenic organisms) must be removed, but most of the dissolved solids may pass through the membrane without causing problems downstream or in the finished water. UF will remove most turbidity from water.

In this regard, Conquest provides Marketing & Sales Services to 5 major manufacturers of Water Treatment & Purification Systems and equipment for Bottled Water Plants.

BOTTLED WATER BUSINESS POTENTIAL




It wasn't until the late 1970's that the bottled water industry began to make its unprecedented climb toward what has become the world’s fastest growing bottled beverage of choice. Before that time most bottled water in the U.S. was mainly imported to satisfy customer demand for health or fashion considerations.



The two most important factors that prompted this increased demand were -- first, public awareness of real problems with the quality of public drinking water supplies, fueled in part by the U.S. Safe Drinking Water Act – and, second, bottled water becoming a preferred alternative to sugar-laden soft drinks as a thirst quencher.

Because of these factors, the bottled water industry has seen double-digit growth for nearly two decades, and most experts expect this growth to continuously expand.

The demand for clean, fresh water is everywhere. Whenever you live -- in the U.S. or abroad -- an unfilled market niche exists for Safe Pure Bottled Water.

The Water Business is one of the most lucrative and profitable enterprises worldwide due to the fact that every human being on earth must have Safe Pure Water on a daily basis to stay alive.

There is in fact a severe shortage of available Potable Water Sources for Drinking & Cooking -- with 99.5% of the earth's water locked-up in Ice Bergs or Ocean Salt Water.


With the remaining 0.05% of available water becoming increasingly polluted with Disease Causing Microorganisms, Chemicals and Other Contaminants, more and more people are turning to Bottled Water to avoid the putrid water that is encountered with most Municipal Water Sources. Alarmingly, many cities in the U.S. are recycling Sewer Water to produce Drinking Water!


An incredible potential exists in the Bottled Water Business for those getting on board at the Present Ground Floor Level of Opportunity as the demand for Bottled Water goes through its present state of Lift-Off Velocity to a Supersonic Hyper-Growth State of Acceleration throughout the world as concern grows over the ever-decreasing sources and increasing contamination of the world supply of Potable Water for Drinking and Cooking.

Conquest has combined several different water treatment technologies to provide our customers with reliable, consistent and great tasting bottled water. These various technologies are well recognized in the water treatment industry and are accepted by government agencies throughout the world.

Bottled water, it may be noted, should not be taken as an appropriate replacement to a sufficient service of tap-water as due to the lack of it, hapless buyers are forced to use bottled water. During the past thirty years, use of bottled water is increasingly moved up the world over, as it has become a global phenomenon. Bottled water sector, despite its excessively high price compared to tap water, is measured as one of the powerful sectors of all the food and beverage trade as its consumption increases by an average of 12% every year. Government has termed the bottled water market, with 33 million liters of consumption per annum in 1999, as small but positively on the rise. It is envisaged that a bottle of 1.5 liters has a production cost of Rs. 12.51 only. In United States, bottled water costs between 0.25 dollar to 2 dollar per bottle, while tap water costs less than US$0.01. This shows high rate of return in this field.

In our country, there are approximately twenty to thirty companies engaged in this business. Official figures show an estimated number of 26 corporations, while in summer time, this number increases up to 70. But from the perspective of quality control, Pakistan Council of Renewal Water Resources is witnessing a fluctuation in the market of 50 percent.

Why the experts at PWC Services are the most trusted in the field:

The idea at PWC is to do business in a way that the whole team feels good about. This means a few things:

• That we are consultants - not salespeople. We never (ever) try to "close the deal".

• That we consult with each client for as long as it takes to understand their water concerns exactly - and then recommend a solution that fits their needs perfectly.

• To install nothing but quality equipment.

• To price our service and equipment reasonably.

• To take pride in every installation - do it right or not at all.

• To never lose sight of the fact that it is the customer we are working for: Be on time, take the time to answer all questions, install and service with the highest standards and then follow up.

• To be a company with integrity in every way possible.

Like the expression goes, a happy customer will tell ten people. But an unhappy customer will tell one hundred. Make it right and the business will grow. Thankfully, PWC’s happy customers and the majority of our business comes from their referrals. But don't take our word for it
