How is Membrane bioreactor modules cleaned?

Membrane bioreactor modules are an integral component of MBR wastewater treatment systems. The membranes in the MBR Membrane Bioreactor modules are prone to fouling due to the accumulation of organic and inorganic particles over time, which can reduce the effectiveness of the system. Therefore, regular cleaning of the MBR Membrane Bioreactor modules is necessary to maintain its performance.

backwashing

Backwashing:

Backwashing involves reversing the flow of water through the membranes to dislodge accumulated particles. This method is effective for removing loosely adhered particles from the membrane surface.

Air scouring

Air scouring:

Air scouring involves introducing compressed air into the membrane tank to agitate the wastewater and dislodge particles from the membrane surface. This method is effective for removing more tenaciously adhered particles.

Chemical cleaning

Chemical cleaning:

Chemical cleaning involves the use of cleaning agents, such as sodium hypochlorite, hydrogen peroxide, or citric acid, to dissolve and remove fouling from the membrane surface. Chemical cleaning is effective for removing stubborn fouling.

Mechanical cleaning

Mechanical cleaning:

Mechanical cleaning involves physically scrubbing the membrane surface with a brush or sponge to remove fouling. This method is effective for removing large, stubborn fouling deposits.
