Equipment Introduction of pure water equipment Pure water one is mainly used by reverse osmosis membrane technology.The working principle of pure water equipment produced by Qin Taisheng industry is to exert certain pressure on water,Make the mineral elements of water molecules and ion states pass through the reverse osmosis membrane,Most of the inorganic salts dissolved in water (including heavy metals), organic matter, bacteria, viruses, etc. cannot pass through the reverse osmosis membrane,Thus, the purified water infiltrated is strictly separated from the concentrated water that cannot be infiltrated.The process flow of pure water equipment is: raw Water → original water tank → raw water booster pump → quartz sand filter → activated carbon filter → Scale Inhibitor dosing equipment → precision filter → Primary high pressure pump → Primary reverse osmosis system → secondary high pressure pump → secondary reverse osmosis system → pure water tank → water supply pump → the process composition of ultraviolet st

Why should not the washing intensity be too large? The strength of the recoil is too large,Filter layer expansion is too high,It will reduce the number of filter particles in the unit volume fluidized bed,Reduce the chance of collision,The effect of reverse washing is poor,In addition,It will also cause the loss of filter materials and waste of flushing water.So not too big haha,Where is the subject of the landlord?What is 'why should the washing intensity not be too large '?
