Abstract
Membrane fouling is the main problem in Membrane Bioreactor (MBR). The characteristics of microbiology and hydrodynamics of membrane fouling in a membrane bioreactor were investigated in this paper. The methods were presented for MBR optimum operation, which were the parameters of MLSS and membrane flux should be lower than critical MLSS and critical membrane flux respectively, as well as discharge of activated sludge for a period properly.
A significance statement is not available in the OpenAlex record.
