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.
