What is Reverse Osmosis Water Treatment System?
Reverse osmosis water treatment system is usually composed of raw
water pretreatment system, reverse osmosis purification system and
ultra-purification post-treatment system. Membrane separation
technology is applied to remove charged ions, inorganic matter,
colloidal particles, bacteria and organic matter from water.
Reverse osmosis membrane system is the most economical and
efficient purification method to remove more than 98% ions, organic
matter and 100% microorganisms (theoretically) in raw water at one
Working Principle of Reverse Osmosis Water Treatment System:
When a pressure greater than osmotic pressure is applied on the
saltwater side of the membrane, the flow of water is reversed and
the water in the saltwater flows into the fresh side, a phenomenon
called reverse osmosis.

Process flow of reverse osmosis water treatment system:
Raw water → original water tank → original water pump → multi-media
filter (quartz sand filter)→ activated carbon filter → soft water
processor → precision filter → high pressure pump → first stage
reverse osmosis (RO) device → pure water tank → high pressure pump
→ second stage reverse osmosis → ultraviolet sterilization device →
Unique Characteristics of Water Purification System Equipment:
1. The single-membrane desalination rate can reach 99%, the
desalination rate of the primary reverse osmosis system can
generally be stabilized above 90%, and the desalination rate of the
secondary reverse osmosis system can generally be stabilized above
2. Because the reverse osmosis equipment can effectively remove
microorganisms, organic substances and inorganic substances such as
iron and silicon, the quality of the effluent is higher than other
3. The equipment has small footprint, compact structure, reliable
operation and convenient operation.
4. The system is simple, the degree of automation is high, the
fault is automatically shut down, and it has the function of
5. The recovery rate can reach more than 70%.
6. Save the chemical consumption cost, labor cost and waste water
treatment cost generated by regeneration, and reduce environmental
1, What are the inlet water quality requirements for ro water
treatment system membrane components?
2. What is the material of ro water treatment system membrane?
Acetate membrane (CA) : mainly because of its resistance to
chlorine, so it is still durable. But its suitable pH range is
small, easy hydrolysis
Aromatic polyamide membrane (PA) : water almost can not have
chlorine, only through a variety of pretreatment chlorine.
3. RO water treatment system configuration:
First-stage multi-stage process: if the recovery rate is not
achieved in the first stage (50-65% in the first stage and 65-75%
in the second stage), the multi-stage tandem filtration can be
used. The effective cross-sectional area of each segment decreases.
2:2 and 2:3 and 4:2:1
Multi-stage process: when the first stage process cannot meet the
effluent quality requirements (the first stage is generally
≤20μs/cm), the product water of the first stage process is sent to
another reverse osmosis unit.
The arrangement of membrane components can be divided into series
