MBR membrane And RO membrane are two common membrane technologies, which have different functions and advantages in different application scenarios.

MBR membrane, namely membrane bioreactor, is a membrane technology integrating biological reaction and membrane separation. It uses the biodegradation of microorganisms to remove organics, and at the same time, it separates microorganisms and pollutants through microporous membranes to achieve the purpose of water treatment. The application scenarios of MBR membrane mainly focus on the following aspects:

1. Urban sewage treatment: MBR membrane technology is widely used in urban sewage treatment. Its main advantage is that it can achieve high standards of discharge requirements and good treatment results.

2. Industrial wastewater treatment: MBR membrane technology is also widely used in industrial wastewater treatment. It can be used for the treatment of organic wastewater, dye wastewater, printing and dyeing wastewater, etc.

3. Sewage reuse: MBR membrane can also be used for sewage reuse, and the treated water can be used for irrigation, flushing, industrial water, etc.

4. Seawater desalination: Compared with traditional seawater desalination technology, MBR membrane technology can better remove organics and microorganisms, ensure the stability of water quality, and can be used for seawater desalination water supply.

RO membrane, namely reverse osmosis membrane, is a membrane technology that uses pressure to separate water and gas. The application scenarios of RO membrane mainly focus on the following aspects:

1. Drinking water treatment: RO membrane is widely used in drinking water treatment, which can remove most ions, microorganisms, organics, etc. At the same time, RO membrane can ensure the quality and safety of drinking water.

2. Industrial water: RO membrane can be used to treat industrial water, such as pure water and ultrapure water in pharmaceutical, electronic and other industries. It can remove impurities and ions in water, ensure water quality stability, and reduce resistance and maintenance costs of equipment.

3. Seawater desalination: RO membrane technology has also been widely used in the field of seawater desalination. It can remove most of the dissolved solids and most of the microorganisms in seawater, and convert seawater into fresh water for water supply, industrial water, agricultural water and other purposes.

4. Wastewater treatment: RO membrane can also be used to treat industrial wastewater and sewage to remove ions, organics and other impurities.

In conclusion, MBR membrane and RO membrane have different application scenarios, both of which have unique advantages and applicability. In practical application, appropriate membrane technology should be selected according to the actual situation and needs.
