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
time.
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 →
water point
The latest development of RO membrane includes inorganic membrane,
hybrid membrane and novel organic membrane. Theoretically,
inorganic membrane has high ion interception performance, but its
high cost and harsh preparation conditions are not conducive to
industrial application. Hybrid membrane combines the advantages of
organic materials and inorganic materials, which has a good
application prospect in improving membrane separation performance
and anti-pollution, and has great development potential, which
needs further theoretical research. The preparation of new organic
membranes is still in the primary stage, and the main purpose is to
improve membrane flux and chemical stability, but no breakthrough
has been achieved.
FAQ:
1, What are the inlet water quality requirements for ro water
treatment system membrane components?
Items | NTU | SDI | Residual chlorine(mg/L) | Fe2＋(mg/L) | TOC(mg/L) |
| Limits | ≤1 | ≤5 | | ≤4 | ≤3 |
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
and parallel.
