Filtration Filtration has emerged in the last two decades as the forerunner of water treatment technology. Its innovative process is the only purification technique than can effectively remove chlorine the primary contaminant of municipally treated water. The filtration process utilizes a filter media through which water passes. Such filter media range from sand for older filters and solid block carbon or carbon media mixtures for newer filters. The filtration process generally involves several stages, through which contaminants are removed in order of importance. In the first stage of filtration, the more concentrated chemicals, like chlorine and VOCs, are removed from water. This preliminary removal allows the remaining stages of filtration to focus on contaminants like pesticides and bacterial matter that are more difficult to remove unless the filtration is as fine as .5 or .1 micron. The subsequent stages of filtration focus on the removal of metal contaminants, like mercury and arsenic, and chemicals from pesticide runoff, such as nitrate . KDF is best for this. As the water passes through the stages of filtration, contaminants are both physically and chemically blocked from passage through the filter media. Contaminants that are physically larger than the granules of the media will be blocked from passage while other undesirable elements of drinking water (such as chlorine and VOCs) are encouraged to break their chemical bond with the water molecules and attach to the filter media. One of the primary reasons why filtration has become the best method of water treatment in recent years is its use of both chemical and physical processes to block contaminant passage. Solid block carbon and multimedia filters are not merely the only water treatment products that can remove chlorine and VOCs from drinking water; they are also capable of retaining healthy, pH-balancing minerals in drinking water. The adsorptive process of such filters attracts chlorine and VOCs to the filter media while allowing mineral sediments to pass through the filter. Choices of water treatment, and best uses of reverse osmosis, distillation, and filtration. Reverse Osmosis is a process of water treatment that was originally used for desalinating of seawater, involving a semi-permeable membranes constructed from a polyamide-based material a source of pressure. Water is forced to move against its natural flow pattern (osmosis) from a solution of high saline concentration to a solution of low saline concentration through the semi-permeable membrane. The object of reverse osmosis is to block the passage of salt particles through the membrane, resulting in a solution of purified water on one side of the membrane and a solution of highly concentrated, salt water on the other side. In recent years, reverse osmosis has been adapted to treat freshwater for drinking water purposes. While reverse osmosis is highly effective at desalinating seawater, there are some aspects to the process that make it undesirable for treating drinking water. First of all, the semi-permeable membrane is only designed to remove particles from water that are physically larger than water molecules. The membrane will remove mineral components and most heavy metals from drinking water, but it will not remove chlorine and other synthetic chemicals. Such chemicals are physically smaller than water molecules and can pass easily through the membrane. Reverse osmosis is rather wasteful and costly. Generally, three gallons of water are wasted for every one gallon of purified water produced. Distillation is used primarily as a means of producing alcoholic beverages--has existed for millennia. Distillation reached its peak of popularity in the 1970s, but due to its costliness and general inefficiency as a water treatment process, it has now been largely relegated to the purposes of scientific laboratories and printing shops. Still, distillation continues to be used--in small measure--as a method of drinking water purification . In the distillation process, contaminated water is heated until it reaches its boiling point. Once the water has begun to evaporate, the heat is kept at a constant to ensure that contaminants with a higher boiling point than water do not also evaporate. The steam from the water is led through a series of tubes into a separate container where it is allowed to condense into the liquid form. The object of distillation is to produce pure water in the second container while retaining any contaminants in the first container. Distillation, because of its constant heat source, will remove any contaminants with a higher boiling point than water. Such contaminants include minerals, heavy metals, and many chemicals from pesticide runoff. They do not include chlorine and VOCs, which have a lower boiling point than water. Consequently, distillation is not highly effective at providing safe drinking water. Like reverse osmosis, it is also incredibly inefficient, wasting nearly 80% of the water it uses. Compare bottled water to filtered water. 1 800 968 9355 to consult There are no regulations or means of ensuring bottled water quality- it is a self-policed industry . Home water treatment industry is very heavily regulated. Manufacturers must do extensive testing and reporting to prove their products effectiveness at providing quality water and are required to supply "Performance Data Sheets" demonstrating the water filters and purifiers do actually remove contaminants that are specified. Bottled water companies are not required to demonstrate their waters quality Total Dissolved Solids measure total weight of all solids dissolved in water- primarily calcium and magnesium and would not be a measurement of contamination. Tests which measure the conductivity of water (often used by companies selling reverse osmosis and distillation system ) only give a rough estimate of dissolved solids, mostly minerals, and do not show water quality. Implying that these tests show water quality is highly misleading and should be considered unethical. Chlorine effects on your skin and hair and immune system. Chlorine was first added to a community water system in 1908 in Chicago to remove bacteria and pathogens that cause waterborne disease such as Cholera and Typhoid fever. Prior to chlorination, cities had death tolls of 1 in 1000 people from Typhoid alone. Chlorine has been used to disinfect municipal water for over 80 years and has had positive effects on eradicating Typhoid and Typhoid like water borne diseases and cholera . In the 1970's it was discovered that chlorine, when added to water, forms Trihalomethanes (chlorinated by-products) by combining with certain naturally occurring organic matter such as vegetation and algae. In 1992 the American Journal of Public Health published a report that showed a 15% to 35% increase in certain types of cancer for people who consume chlorinated water. This report also stated that much of these effects were due to showering in chlorinated water. The National Cancer Institute estimates cancer risks for people who consume chlorinated water to be up to 93% higher than for people who do not. The effects of drinking chlorinated water have been debated for decades. However, most experts now agree that there are some significant risks related to consuming chlorine and chlorinated by-products in drinking water. So the conclusion is that we need chlorine and then we need to remove it. Virtually all city water systems contain some level of chlorine. The level will vary based on outdoor temperature, the season, distance from water utility and current usage. While chlorine may sometimes be undetectable on a certain day with a standard OTO test kit, that level can change dramatically day to day. Also some cities use ammonia at certain times as a disinfectant in order to reduce chlorination by products. Without chlorine the dangers of water borne disease would be too significant. An undetectable chlorine level, on a certain day, does not eliminate the need for an effective home filtration system. Water and contamination with radioactive matter? Radioactive water is not very common in this country and is a more serious problem than should be dealt with by a home water filtration system. Many people confuse the contaminant "Radon" with radioactivity when in fact they are quite different. Radon is produced from decaying Uranium ore and can be effectively removed by carbon filtration. VOCs in water. Volatile Organic Chemicals are synthetic compounds that turn into vapor at relatively low temperatures. VOCs typically vaporize at a much lower temperature than water. Most synthetic chemicals found in water, such as pesticides and herbicides, are VOCs.and for this reason we need to filter and purify the water we drink Well water . There are many health and cosmetic benefits to removing chemicals and compounds from shower water, even on non-chlorinated private wells. Virtually all ground water contains traces of some chemical or chemicals that can be absorbed through the skin or inhaled. Also the Aquasana shower filter system helps balance the waters pH, which is also a very noticeable cosmetic benefit. Storing filtered water. Glass is always best, for spring water or a high grade polycarbonate material. Clear plastic bottles and pitchers with a #1 in the recycle triangle on the bottom, like the bottles used by Evian and the higher quality bottled waters, are the best option for water storage since they have been shown to release the lowest levels of plastic component chemicals into water. Translucent, colored or bottles with a number other than 1 on the bottom should be avoided because there is the possibility of higher levels of chemicals leeching into the water from the plastic. Question: Are whole house systems ( point-of-entry) better than counter-top filters (P.O.U.- point-of-use)? P.O.U. Systems are by far the best way to ensure the highest quality water since many water-borne contaminants come from the plumbing in your house, especially lead and vinyl chloride from the piping. By filtering water at the point-of-use you remove contaminants just prior to consumption, eliminating the chance of recontamination. All public water systems contain some level of one or more unhealthy chemicals. Regulations only require periodic testing of about 90 chemicals. There are now more than 75,000 chemicals used in our society with over 1000 new ones being developed each year. Contaminant levels fluctuate throughout the year making it impossible to know the actual level of contamination in a central water system. So far over 2100 toxic chemicals have been detected in America's water systems. The risk is high; the cost for a sure solution is low, 9 cents per gallon with Aquasana. Some people are more sensitive to chemicals in drinking water and shower water than others. Small children,elderly , chronically ill, immune compromised, chemically sensitive, allergic are especially more affected by contaminants in water due to a reduced capacity to deal with toxins and an underdeveloped or less tolerant immune system.e most important thing to remember is that no matter how insistent these reports are that "contaminants in your water do not necessarily pose a health risk", any level of contamination in our drinking water does in fact represent a danger to our health. Of the over 75,000 toxic chemicals used in our society, the EPA has only set standards (MCLs) for about 90, and those 90 Maximum Contaminant Levels are not necessarily set on "health effects." The EPA considers limited health studies based on consumption of one certain chemical by a 175 lb. Adult when setting these standards. No consideration is given to the effects on small children or the combined effects of two or more contaminants, which some studies show are magnified by as much as 1000 times. Water utilities are only required to test for the 90 contaminants that the EPA has set standards for. Nobody knows how many toxic chemicals may actually be in tap water. According to the Ralph Nader Research Group, after reviewing thousands of pages of EPA documents acquired through the Freedom of Information Act, more than 2100 toxic chemicals have already been detected in U.S. Water supplies. Virtually all public water systems have some level of contamination. The water utilities are usually quick to point out that the chemicals found in their water are "below EPA's Maximum Levels", and in most cases they are. The fact is that even the smallest trace of a toxic chemical causes damage and science is just now starting to realize to what extent. In a recent report from the National Cancer Institute to the Surgeon General it was stated that "No level of exposure to a chemical carcinogen should be considered toxicologically insignificant to humans," and we are learning the hard way the truth of this statement.
