Reverse osmosis membraneROWorking principle

RO(Reverse OsmosisReverse osmosis technology is a membrane separation filtration technology that uses pressure difference as the driving force and has a small pore size

Nanoscale1"Nanometer=10-9meter Under certain pressure,H2OMolecules can pass throughROMembrane, while inorganic substances in the source water

Impurities such as salts, heavy metal ions, organic substances, colloids, and viruses cannot pass throughROThe membrane, thus allowing it to pass through

Pure water and concentrated water that cannot pass through are strictly distinguished.

The working principle diagram of the reverse osmosis membrane is as follows

The following figure shows the principle diagram of reverse osmosis and the conventional process flow chart:

The reverse osmosis device mainly consists of a high-pressure pump, reverse osmosis membranes and a control section. The high-pressure pump pressurizes the source water to remove water molecules

It can be accessed throughROOutside the membrane, almost all other substances in the water (minerals, organic matter, microorganisms, etc.) are rejected outside the membrane.

impenetrabilityROThe membrane was washed away by high-pressure concentrated water.

The characteristics of reverse osmosis technology

1The desalination rate of reverse osmosis is high, and the desalination rate of a single membrane can reach99%The desalination rate of a single-stage reverse osmosis system is generally stable

in90%As mentioned above, the desalination rate of the two-stage reverse osmosis system can generally be stabilized at98%That's all.

2Due to the fact that reverse osmosis can effectively remove microorganisms, organic matter, and inorganic substances such as metal elements, the quality of the effluent water

It is far superior to other methods.

3Reverse osmosis for pure water production has low operating and labor costs and reduces environmental pollution.

4It slows down the changes in the quality of the produced water caused by the fluctuations in the quality of the source water, thereby facilitating the stability of water quality during production.

This has a positive effect on the stability of pure water product quality.

5It can significantly reduce the burden on subsequent processing equipment, thereby extending the service life of subsequent processing equipment.
