Why MBR?

Activated sludge process consisting of an aeration tank and a membrane unit that separates treated effluent from bio-solids

Membrane provides an absolute barrier based on particle size. No solids carry-over occurs enabling exact control of the solids retention time (SRT)

The system promotes slow growth microorganisms and degradation of constituents that are normally considered recalcitrant

ALWAYS HIGH QUALITY

Membrane filtration always assures high quality discharge• Positive filtration prevents upsets

No upsets possible• Sludge bulking does not matter

High MLSS concentration assures high rates of treatment• Changes in feed strength are more easily accommodated

No treatment chemicals required for sludge settling

High consistent quality allows for possibility of reuse with no worries about system upsets

MBR for INDUSTRIAL WASTEWATER

Membrane allow higher concentrations of mixed liquor suspended solids (MLSS) to be maintained under aeration

Quality of the effluent and its reliability are increased through MBR technology

With the use of UF membranes, the effluent can be free of bacterial contamination and suitable for reuse
