EMTECH400G: water purifier designed for ensuring perfect mineral in your drinking water system. This purifier is great for light commercial use in Restaurants, Labs, Salons, Cafes, Offices, Schools, Mess, etc. EMTECH400G water Purifier utilizes the unique properties of a semi-permeable membrane to allow fluid to pass while restricting the flow of dissolved ionic material. This Purifier with applied pressure to passing impure water on the side of such membrane materials, pure water will pass through, leaving most of the impurities behind. The rejection of the dissolved ionic material is a function of both molecular weight and ionic charge. For example, we can expect a nominal 90% rejection of sodium chloride, which means that the product water passing through the membrane will have a concentration of salt approximately one-tenth that of the feed water. Finally the treated water passing into ultra-violet technology system sterilizer to kill genetically all virus & bacteria. Also this purifier rejection of calcium carbonate (hardness) will be near 95%, while most metallic salts will be rejected at a rate of approximately 90% to 99%. Also it’s capable of removing over 85% of TDS,+95% of all organics and +99% of all bacteria. Finally the treated water passing into ultra-violet technology system sterilizer as a result rest any single micro germs genetically damaged by ultra-violet light.
