Membrane bioreactor (MBR)
In a membrane bioreactor (MBR), the separation of activated sludge and treated water takes place, not by sedimentation, but by membrane separation. This allows higher sludge concentrations to be achieved, thereby saving space and ensuring better treatment of difficult-to-decompose waste water.
- hollow fibre membranes
- plate membranes
- tube membranes
MBR has several advantages. Higher sludge concentrations can be achieved and effluent quality is better. Space saving, more poorly degradable waste water or the desire to reuse the treated water are the customary incentives when opting for an MBR.
