Membrane Bioreactors

Membrane Bioreactors

The benefits of Membrane Bioreactors includes a reduced footprint, usually 30-50% smaller than an equivalent conventional active sludge facility with secondary clarifiers and media tertiary filtration.

Description

Description
Membrane bioreactors are used to treat sewage and wastewaters and achieve purification with respect to biochemical oxygen demand, chemical oxygen demand, total suspended solids, ammonia, total nitrogen and total phosphorous. Membrane bioreactors for wastewater treatment is a combination of a suspended growth biological treatment method, usually activated sludge, with membrane filtration equipment, typically low-pressure microfiltration or ultrafiltration membranes. The membranes are used to perform the critical solid-liquid separation function. In activated sludge facilities, this is traditionally accomplished using secondary and tertiary clarifiers along with tertiary filtration. The benefits of Membrane Bioreactors includes a reduced footprint, usually 30-50% smaller than an equivalent conventional active sludge facility with secondary clarifiers and media tertiary filtration. The process also produces exceptional effluent quality capable of meeting the most stringent water quality requirements, a modular schematic that allows for ease of expansion and configuration flexibility, a robust and reliable operation and reduced downstream disinfection requirements.
