Comparison between FBBR and MBBR vs MBR
An MBR (Membrane Bio Reactor) plant uses biological breakdown and physical separation. It is a filtration facility with an upstream activated sludge buffer. The sludge production
is less than that of FBBR (Fixed Bed Bio Reactor) and MBBR (Mixed Bed Bio Reactor),due to a concentration of bacteria that is 4-5 times higher (held within the membrane). On top of that, there is no sludge settlement required, so less space is needed.
