Philadelphia Scientific: HydroPure Water Deionizing System (Single)

PHILADELPHIA SCIENTIFIC: HYDROPURE WATER DEIONIZING SYSTEM (SINGLE)Philadelphia Scientific’s Hydropure Water Deionizing System comes with everything you need to make your own pure water right from your own tap: a wall-mounting plate, one high-capacity Deionizer cartridge, purity light, hose hanger, quick connects and input and output hoses. Installation takes just minutes — and replacing spent cartridges takes just seconds.Battery water should be free from metallic impurities because they can affect cell voltages and self-discharge. Also to be limited are calcium and magnesium compounds found in hard water because these may cause mossing and dendrite growth through the separators. Note that these impurities are dissolved in the water and cannot be removed by conventional filters.Professional quality deionizers: Not just a filter, which only removes particles, but a real ion-exchange medium which electrostatically removes dissolved impurities. Purity is comparable with distilled water and ideal for batteries.Philadelphia Scientific’s Deionizer system reduces the high price of buying bottled water and is more convenient as well.How does it work?Inside the Deionizer, tap water is passed through a cartridge containing beds of cationic and anionic resins which electrostatically remove impurities. The result is very pure water. When the cartridge becomes exhausted it is simply replaced with a fresh one.Purity ChartThe following chart can be used to determine how many gallons of pure battery water can be obtained from one cartridge based on the purity of the incoming tap water.Purity of Tap WaterTotal Dissolved SolidsCartridge CapacityPPMGrainsuS/cmU.S. GallonsLitresGood5032814405,451754429603,634Average1006567202,7251207676002,2711509844801,817Poor200121123601,363250151402881,090* TDS means Total Dissolved Solids in the water ** Parts per million is equal to mg/litre of water
