MEMBRANE BIOREACTORMEMBRANE BIOREACTOR
Conventional:
• low MLSS (3-5 g/l)
• low age activated sludge
• only floc forming bacteria
• only fast growing bacteria
• low chance for component-specific bacteria
• sludge carry-over
• effluent polishing required
MBR:
• medium MLSS (10-20 g/l)
• high age activated sludge
• all kind of bacteria survive
• less sludge production
• good chance for component-specific bacteria
• no sludge carry-over
• high quality effluent
