• In stage 1
, Water travels through a 1 micron solid carbon cartridge for removing volatile organic carbon compounds (VOC's), insecticides, pesticides and industrial solvents and traps particles larger than 1 micron including sediment, silt, sand and dirt. It also helps to extend the life of the system.
• In stage 2, water passes through a .01 micron Ultrafiltration (UF) membrane. Ultrafiltration (UF) is an important purification technology used for the production of high-purity water. UF is effective for the removal of colloids, proteins, bacteria, viruses, parasites, protozoa and pyrogens (e.g., gram-negative bacterial endotoxins), other organic molecules larger than .01 micron, and most other water contaminants known today.
• In stage 3,Water flows through pre one - micron filter pads (1 micron equals 1/25,000th of an inch), which removes suspended particles such as silt, sediment, cyst (Giardia, Cryptosporidium), sand, rust, dirt, and other undissolved matter
• In stage 4, water passes through granulated activated carbon (GAC). GAC is universally recognized and widely used as an effective adsorbent for a wide variety of organic contaminants, such as chlorine (99.9%), chemicals linked to cancer (THM's, benzine) pesticides, herbicides, insecticides, volatile organic compounds (VOC's), PCB's, MTBE's and hundreds of other chemical contaminants that may be present in water, bad taste, and odors from your drinking water.
Granular activated carbon is a highly adsorbent material used to remove contamination from water Activated carbon has been known as a miracle filter media by many researchers because of its unique ability to remove offensive tastes, odors, color, chlorine and volatile organic chemicals, pesticides and trihalomethanes (a group of suspected carcinogens). Briefly, activated carbon acts like a sponge, with a large surface area to absorb contaminants in the water.The surface area of one pound of activated carbon is equal to 125 acres.Many scientists believe this is a result of an affinity that these chemicals have for carbon because of Van Der Waal forces. Activated carbon is the preferred treatment and method recommended by the EPA to remove a host of potentially hazardous and possibly carcinogenic chemicals in drinking water.
• In stage 5, Water flows through the ion exchange resin, reducing heavy metals such as lead, copper, aluminum, and water hardness.
• In stages 6 and 7,water flows through 2 beds of Redox (Oxidation/reduction process) media made of a special high-purity alloy blend of two dissimilar metals - copper and zinc.
Redox (Oxidation/reduction process) media is completely safe and meets EPA and FDA standards for levels of zinc and copper in potable water, so the process is not toxic and does not cause any adverse side effects.
Representing a new and unique way of water processing medium which by its natural process of electrochemical oxidation/reduction and adsorption action reduces and/or removes many unwanted contaminants from water. It is a major advancement in water treatment technology that works on the electro-chemical and spontaneous-oxidation-reduction (REDOX) principles. Chlorine is instantaneously and almost inexhaustibly oxidized.
Iron and hydrogen sulfide are oxidized into insoluble matter and attach to the surface of the media. Heavy metals such as lead, mercury, copper, nickel, chromium, cadmium, aluminum, and other dissolved metals are removed from the water by the natural process of electrochemical process. They are attracted to the surface of the media, much like a magnet. The media inhibits bacterial growth throughout the entire unit.
Redox (Oxidation/reduction process) media works to reduce or remove chlorine, iron, hydrogen sulfide, lead, mercury, calcium carbonate, magnesium, chromium, bacteria, algae, and fungi. Redox media removes up to 98% of water-soluble cations (positively-charged ions) of lead, mercury, copper, nickel, chromium, and other dissolved metals. In most cases, more than 98% of chlorine is removed if operated within recommended flow rates.
Redox (Oxidation/reduction process) media alloys function as catalysts to change soluble ferrous cations (positively-charged ions) into insoluble ferric hydroxide, which can be removed with regular backwashing. With enough oxygen dissolved in the water, iron removal rates of 98 percent or better are common.
• In stage 8,Water flows through another one-micron filtration pad for further reduction of undesirable particles. The end result is a great reduction or elimination of a wide variety of contaminants.
• In stage 9,Water passes through a reverse osmosis membrane, which removes and filters particles as small as 1/1000 of a micron as most inorganic chemicals (such as salts, metals, minerals) most microorganisms including cryptosporidium and giardia, and most inorganic contaminants.
• In stage 10 and 12, Water flows through another one - micron filter pads(1 micron equals 1/25,000th of an inch), which removes suspended particles such as silt, sediment, cyst (Giardia, Cryptosporidium), sand, rust, dirt, and other undissolved matter.
•In stage 11, water passes through granulated activated carbon (GAC). GAC is universally recognized and widely used as an effective adsorbent for a wide variety of organic contaminants, such as chlorine (99.9%), chemicals linked to cancer (THM's, benzine) pesticides, herbicides, insecticides, volatile organic compounds (VOC's), PCB's, MTBE's and hundreds of other chemical contaminants that may be present in water, bad taste, and odors from your drinking water.
• In stage 13, water passes through an Ultraviolet Water Sterilizer System manufactured with axial flow reactors in 304 stainless steel. The hard glass germicidal lamps provide an economical way of treating water requiring a 99.99% reduction of bacteria and virus and protozoa. This process is accomplished without adding any harmful chemicals to your drinking water. Ultraviolet Water Sterilizer System is the most ecological way of treating your water.
