What are the important indicators of drinking water reverse osmosis system?
In the selection of reverse osmosis equipment, there is an extremely important index - desalination rate, which determines the quality of produced water. The abolishment rate is the percentage of soluble impurities removed from system influent by reverse osmosis membrane. This number can be seen from the ability of reverse osmosis membranes to filter impurities from water.
In addition, there are organics, microorganisms, solid particles and residual chlorine in the water, which pollute the ro membrane, so it needs to be pretreated to avoid membrane surface blockage and damage and reduce the desalination rate.
Drinking Water RO System workflow:
raw water - raw water tank - raw water booster pump - quartz sand filter - activated carbon filter - scale inhibitor dosing equipment - precision filter - first-stage high pressure pump - first-stage reverse osmosis Host - intermediate water tank - secondary high pressure pump - secondary reverse osmosis host - disinfection system - production water.
