A- Whole House Coconut Shell GAC Carbon Whole House Filter. Carbon is a substance that has a long history of being used to absorb impurities and is perhaps the most powerful absorbent known to man. One pound of carbon contains a surface are of roughly 125 acres and can absorb literally thousands of different chemical. Activated carbon which has a slight electron-positive charge added to it, making it even more attractive to chemicals and impurities. A filter with granular activated carbon (GAC) is a proven option to remove certain chemicals, particularly organic chemicals, from water. GAC filters also can be used to remove chemicals that give objectionable odors or tastes to wate. Upper & Lower Basket. Coconut Shell Carbon media 1 cu ft. Upflow systems direct the water in the up flow direction of the system. The water comes into the water system tank and flows through an upper basket and then down a riser tube in the middle of the tank. Once the water reaches the bottom of the tank, it is then distributed through a lower basket attached to the riser tube. Th water then flows from the bottom of the tank through the filter media in a swirling motion. The swirling motion is created by the reaction of the water coming out of the lower basket coming in contact with the bottom of the filter with the bottom of the filter tank which is round or curved. A upflow design eliminates the need for backwashing on most filters because the media is continuously being fluffed each time the water flows through the tank. Another advantage to an upflow design is the amount of contact the untreated water has with filter media. An up-flow design also forces the filter media to which in turn allows the media to have longer contact time with the water yielding better results. B- SALT FREE WATER CONDITIONER 12 GPM WITH GAC CARBON FILTER UP FLOW VALVE WHOLE HOUSE SYSTEM. NO Salt Water Conditioning. Scale Prevention System (New Technology). NO lime scale buildup on pipes, fixtures or appliances and can even remove existing scale in some cases. Easy Installation, Two Connections, Simple pipe in / pipe out. Saves Water, no backwash required simple flow through to point of use. No power required, No Timer or Backwash cycle. No Chemicals or sale required. No Maintenance, No Drain Required. Will not harm the environment, adds or removes nothing from water while giving the benefits of soft water. The essential calcium and magnesium nutrients removed by traditional water softeners remain and there is no sodium added as with traditional softeners to aggrave cardiovascular or other health problems. 50% less soap and detergents required and enjoy white whites and brighter colors without hard water stains. ยท Calcium ions, magnesium ions and bicarbonate ions in untreated water form scale on the inside walls of pipe, exterior of fixtures and on heating surfaces because crystallization is not taking effect efficiently between the ions due to their suspension between water molecules and the need to come together in the proper alignment to form crystals. Therefore they form as scale on the surfaces of the water system. The system is a simple physical water treatment known as TAC (Template Assisted crystallization) Template=mold, guide or pattern. Assisted=Help or make easy. Crystallization=Form a definite shape. Inside the TAC treatment tank are porcelain beads with the atomic level pattern of the crystal etched on their surface allowing for the calcium, magnesium and bicarbonate ions to come together on the template to created millions of microscopic crystals of scale that rapidly form and are released from the bead immediately into the treated water, not forming on the contact surfaces of the water system and are carried downstream in suspension through the water system. The crystal formation on the microscopic crystals (seed crystals) created on the beads and released in the water stream are the lowest energy reaction possible between the ions therefore existing scale will be dissolved back into the water stream by reacting with and forming crystals. The seed crystals are constantly being formed on the beads and released as catalyst for crystal growth in the water steam. Crystallization is the process that the magnet process and electrical charging of water claim to achieve. But by independent testing the electrical and magnetic methods are a maximum of 60% effective at scale prevention leaving an unacceptable level of 40% scaling. The TAC method is tested at 99.9% efficient at scale prevention and removal. Water Chemistry & Limitations. PH 6.5 to 8.5. Hardness Max 75 Grains (1300 ppm CaCO3). Temperature 41 to 140 F (5-60 C).
