Abstract

Biofilm membrane bioreactor (BF-MBR) is an alternative, hybrid system to the conventional MBR (AS-MBR) for municipal
wastewater treatment. In BF-MBR the moving-bed-biofilm reactor (MBBR) for biodegradation of soluble organic matter is
coupled with a submerged membrane reactor (sMBR) for particle separation. The moving-bed-biofilm reactor (MBBR) utilizes
the whole tank volume for biomass growth, as well as the activated sludge (AS) reactor, but contrary to AS does not need any
sludge recycle. This is achieved by having the biomass growth on carriers that move freely in the water volume of the reactor.
This characteristics present considerable advantage over the activated sludge process, since no sludge recirculation takes
place, only the surplus biomass has to be separated. Like in all membrane processes, fouling in BF-MBR is a main obstacle that
needs to be understood in order to develop sustainable process.
