Water Purification System

Water Purification System TheROWater Purification System removes the hydronium, organic substance, colloid, bacteria and other impurity by the method of membrane. And the water can be desalted and purified. The theory is as follows. The treated water and the untreated water are separated by the membrane; the treated water osmoses to the untreated water. There is osmotic pressure between the two. If the pressure is added to the untreated water and the pressure of the untreated water is bigger than the osmotic pressure, the water of the untreated water osmoses to the opposite position of the water. This applies the reverse osmosis to the desalted water. That is to say the untreated water is purified into the pure water through the RO membrane under adequate pressure. The left water which can not osmose through the membrane contains a lot of solute and suspended substance, and it will be drained out as waste water. The RO device consists of 5µm precision filter, the first high-pressure pump, the second high-pressure pump, the middle tank, the pressure vessel, the RO membrane module, the PLC, the pressure gauge, the flowmeter, the conductivity meter and etc. The water must be pretreated before entering into the RO system, or it will bring damage to the RO membrane. Function Of Main Components Quartz Sand Raw water into the filter for a simple mechanical filter, mainly to remove suspended solids in water, colloidal particles and other large impurities in the water when the water pressure and the pressure difference over 10Psi (0.7kg/cm2) or water SDI> 5. Active Carbon Activated carbon is used wood, coal, shell (nuclear) and other carbonaceous material made by chemical or physical method activation. It has a very large number of pores and specific surface area, which has a strong physical adsorption capacity, the effective adsorption of organic pollutants in water. Primarily to remove organic matter in raw water, chlorine, odor, color, etc., so that the original residual chlorine in water ≤ 0.1mg / l, effective protection of RO membrane from chlorine damage to parts of activated carbon typically 12 to 18 months to replace a The main residual chlorine as determined in raw water. Softener Get rid of the Calcium and Magnesium,which made the water hard.It use ion exchange resin to change the hardness ion. Membrane has a low operating pressure (low pressure compared with conventional composite reverse osmosis membranes operating pressure reduced by about 25% -40%), while maintaining high desalination rate,
