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
