MBR (Membrane Bioreactor)

Description

The biological treatment process can be aerobe, anoxic or anaerobe. A MBR is suitable for the purification of industrial as well as communal wastewater.
 
In a conventional biological treatment system the wastewater is separated from the active sludge by a settler. In a Membrane Bio Reactor the separation takes place by membranes. Therefore substantially higher sludge concentrations (10 to 18 g/l) and smaller reactor volumes can be used compared to the conventional treatment systems.

Advantages

• Continue discharge of the purified water, 24 hours per day.
• High degree of reliability due to 100% separation of active sludge and water.
• No unsolved particles in the treated water.
• Small footprint of the aeration basin compared to conventional treatment installations with identical capacity
• Very high COD/BOD reduction, up to 99,9%
• Water is suitable for reuse after a relative simple final treatment step.
