MBR membrane (membrane bioreactor) is an important part of the inner support.

Membrane bioreactor (MBR) is a new wastewater treatment technology combining membrane separation technology and biotechnology. The membrane module replaces the end secondary sedimentation tank of the traditional biological treatment technology, maintains a high activated sludge concentration in the bioreactor, increases the organic load of the biological treatment, thereby reducing the footprint of the sewage treatment facility, and reduces the amount of residual sludge by maintaining a low sludge load.
