Pi-Alkaline The Pi-Alkaline Water Filter combines specially positioned ceramic magnets, magnetite as well as 5 other volcanic minerals and ceramics to produce structured water to stabilize pH, improve circulation, increase mental alertness and strengthen the immune system.
Reverse Osmosis Reverse Osmosis Reverse osmosis (RO) is a common treatment technology that produces high quality water. The process works by forcing water under great pressure against a semi-permeable membrane, where ion exclusion occurs. With ion exclusion, water molecules form a barrier that allows other water molecules to pass through while excluding most contaminants. Typical contaminant rejection rates range from 85% to 95%, and a gallon of highly treated water can usually be produced from two to four gallons of raw water, depending on the initial quality of the water. Maintenance involves the replacement of the RO membrane cartridge every two or three years, and the carbon filter cartridges six to twelve times per year. RO is effective for the reduction of a broad range of health and aesthetic contaminants, though it is typically not used for the reduction of biological pathogens. RO also incorporates an activated carbon filter, which can provide added treatment for the volatile organic compounds (VOCs) not treated by the membrane itself. It should be remembered that this brief description of water treatment technologies is only intended to provide an overview of how each technology can be applied to solve a water contamination problem. Water Softener Cation exchange use the chemical ion exchange process to exchange cations on a "resin" bed for cations of the contaminant that needs to be removed from the water. For example, in cation exchange, a cation of hardness mineral such as calcium is exchanged for two cations of sodium, effectively removing most of the calcium, and softening the water. The cations on the resin are eventually exhausted, and replaced by the cations of the contaminant being removed. When this occurs, the bed must be backwashed using a concentrated solution of the base cation, which recharges the bed and flushes the built-up contaminant. Cation exchange typically uses sodium or potassium chloride, and can also treat for some forms of lead and radium. It is also commonly used to soften water. Carbon filtration Activated Carbon (Granular and Solid Block) Granular activated carbon is a well-established technology for the reduction of a wide range of aesthetic contaminants, and is quite effective in the reduction of some health contaminants such as volatile organic compounds (benzene, trichloroethylene, and other "petroleum"-based contaminants. Because of its molecular makeup, activated carbon can adsorb well, meaning that it can take in or collect many organic molecules on its surface. Granular activated carbon filters are typically inexpensive, and maintenance involves replacing six to twelve cartridges a year, depending on the quality of the raw water and the filter media. Specially designed solid block and pre-coat activated carbon filters are also available, which are effective at reducing heavy metals such as lead and mercury. Solid block filters with a pore size smaller than 0.2 microns are often effective against biological contaminants as well. Ultra-Violet System UV radiation can be an effective vermicide and bactericide. Disinfection using UV radiation was more commonly used in wastewater treatment applications but is finding increased usage in drinking water treatment. The primary usage for a UV light is to disinfect filtered water at a certain flow rate. Bacteria, viruses, and other microorganisms are destroyed by the UV interfering with the DNA and RNA in the organisms' reproductive cycles. If your water source is known to be unsafe with microorganisms and you want to have extra protection, then you can add an UV as an additional stage to disinfect water. Ultraviolet water purification lamps produce UV-C or "germicidal UV," radiation of much greater intensity than sunlight. Almost all of a UV lamp's output is concentrated in the 254 nanometers (nm) region in order to take full advantage of the germicidal properties of this wavelength. Most ultraviolet purification systems are combined with various forms of filtration, as UV light is only capable of killing microorganisms such as bacteria, viruses, molds, algae, yeast, and cysts like cryptosporidium and giardia. UV light generally has no impact on chlorine, VOCs, heavy metals, and other chemical contaminants. Nevertheless, it is probably the most cost effective and efficient technology available to homeowners to eliminate a wide range of biological contaminants from their water supply. Recent testing has also shown that UV can be effective at destroying certain VOC's, although we would not specifically recommend the technology for VOC reduction. UV water treatment offers many advantages over other forms of water treatment for microbiological contaminants. Most importantly, it does not introduce any chemicals to the water, it produces no bi-products, and it does not alter the taste, pH, or other properties of the water. Accordingly, in addition to producing safe drinking water, it is not harmful to your plumbing and septic system. Further, it is easy and cost-effective to install and maintain without any special training.
