mbr curtain membrane assembly step description
MBR (membrane bioreactor) curtain membrane assembly is a membrane technology equipment used for water treatment. It uses a microporous filter membrane as a separation layer to intercept suspended matter, bacteria and organic matter in sewage on the membrane surface, while allowing the purified water to enter the water collection pipe through the membrane pores.
MBR curtain membrane assembly usually consists of the following parts:
Membrane module: The membrane module is the core part of the curtain membrane assembly, usually composed of multiple membrane sheets. There is a microporous filter membrane on the membrane sheet, which can effectively intercept suspended matter, bacteria and organic matter.
Airbag: The airbag is located below the membrane module and generates bubbles by gas injection. The role of the bubble is to maintain the permeability of the membrane surface and prevent the membrane pores from being blocked by pollutants.
Water tank: The water tank is the supporting structure of the membrane module, which is used to collect and transport purified water.
The working principle of MBR curtain membrane module is: sewage is sent into the membrane bioreactor through the water inlet pipe, biochemical reaction is carried out in the bioreactor, and the membrane surface is kept clean by the action of bubbles. The purified water enters the water collection pipe through the membrane holes, while suspended matter, bacteria and organic matter are retained on the membrane surface. This membrane technology can efficiently remove suspended matter, bacteria, viruses and organic matter in sewage to produce high-quality purified water.
MBR curtain membrane module is widely used in the field of water treatment, such as urban sewage treatment, industrial wastewater treatment, seawater desalination, etc. It has the advantages of good treatment effect, small footprint, convenient operation and management, etc., and is an advanced water treatment technology.
