drinking water equipment

This RO waste water treatment equipment system is developed on the basis of tap water quality in Guangzhou, China. The process is as follows: The Raw water pump add pressure and pump water into sand filter which contains quartz sands which are used to remove the suspensions, colloids, rust, impurities in water as well as some microbes (such as red worm) →carbon filter which contains high quality first class fruit shell active carbons which are used to remove the organics in water as well as oxygen, bad odor, pesticide and colloids which are not removed thoroughly by sand filter→water softener, which is used to reduce the water hardness by exchange magnesian ion and calcium ion in water through cation resin so as to remove the state of calcium and magnesium ions→security filter which installed two pieces of 5µm PP filter (length 500mm) which are used to remove the impurities(diameter above 5µm). The previous procedure is called pretreatment of RO device which is mainly used to pretreatment for the raw water and ensure RO system work well and prolong the lifespan. After the process of pretreatment, high pressure pump pumped the water into one stage RO system. This system adopt two pcs 4040 membranes which are American DOW membrane., the unit desalination rate is 99%, the whole system desalination rate is 97%-99%(capacity 500L/H well water) under the condition of tap water quality in Guangzhou, the purified water can reach the state drinking water standard in China. (TDS ≤10µs/cm), Recovery rate is 65%, more or less. Equipped with stainless steel zwitterions combined bed will ensure water quality reach 1µs/cm.
