Pretreatment part of RO Purification system includes feed water pump, quartz sand
filter, activated carbon filter, precision filter, and dosing
system. It solves the following problems:
1. Prevent the fouling problems on membrane surface, which
including Fe3, Fe2, CaCO3, CaCO4,SrSO4, CaF2, SiO2, Iron, aluminum
2. Prevent fouling caused by colloidal substances and suspended
3. Prevent fouling of the organic matter.
4. Prevent microbial fouling
5. Prevent oxidation of oxidation irreversible damage of RO
6. Keep the stable output of RO purification machine.
Feed Water Pump
Provide pressure for pre processing unit.
Quartz sand filter Filter
Fill in refined multi-layer refined quartz sand with different
particle sizes. The design should fully consider the flushing
strength problem. The reason of unstable operation of sand filter
caused by unsteady mechanical filter back flush design flows. When
back flush is not enough, the upper filter sand agglomerate SDI
(pollution index) increases, which causes membrane fouling problem.
After sufficient mechanical filter backwash process, the impurities
deposed on sand filter layer surface would be wash away and recover
the penetration ability. In order to improve the filtration
efficiency and reduce the impact on the impurity sedimentation,
timely back wash with compressed air filter material could reduce
the turbidity less than 1 ntu.
Activated Carbon Filter
Activated carbon filter is mainly used to remove organic matter and
residual chlorine. Within absorption of activated carbon, filtrated
water removes 60% of organic matters and large amount of residual
chlorine in feed water. Activated carbon removes residual chlorine
is not a simple adsorption effect, but a catalyst effect after
mechanical filter and reduce SDI less than 4.
To prevent large particles from entering and damage high pressure
pump and reverse osmosis membrane.
Reverse osmosis system
Reverse osmosis membrane is the key part of the system. The
reasonable design directly decides the output quality to meet the
user’s requirements and the service life of RO membrane. Treated
water from reverse osmosis unit can remove bacteria and organic
matter, microorganism and large part of ions in water. There is no
phase transition in process of separation. RO purification system
is widely applied in various working circumstances to get pure
water suitable for drinking without environmental pollution.
