In stage 1, water travels through a a solid carbon cartridge for removing volatile organic carbon compounds (VOC's, insecticides, pesticides and industrial solvents). In stage 2, water travel through a FLUORIDE REMOVAL cartridge. Containing synthetic Aluminum Oxide absorbant media. Specifically designed to have a high affinity for Fluoride, Lead and Arsenic. It removes metals through a mixture of adsorption and chemical reaction with the media, therefore, the elimination is not reliant on ion exchange. It has uniform particle size, is physically stable and can be used over a wide pH range. Capacity: 4500 ppm Fluoride (Avg. 1000 to 1500 Gallons) . As high as 11000 ppm F+ with effluent levels below 0.2 ppm from 10 ppm F+ feed. In stage 3, and 8 water water flows through pre and post one - micron filter pads (1 micron equals 1/25,000th of an inch), which remove suspended particles such as silt, sediment, cyst (Giardia, Cryptosporidium), sand, rust, dirt, and other un-dissolved matter. In stages 4 and 5, water flows through a bed of media made of a special high-purity alloy blend of two dissimilar metals - copper and zinc (KDF-55D ??, and KDF-85D ??.) KDF 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. In stage 6, water flows through ion exchange resins, reducing heavy metals such as lead, copper, aluminum, and water hardness. In stages 7, water flows 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&
