Bioflim MBR (BF-MBR)

Effect of biocarrier on organic loading The maximum allowable volumetric organic loading rate measured by food to volume ratio (F/V) is directly related to the maximum volumetric oxygen dissolution rate (VODRmax) since microorganisms can accommodate any organic loading rate in realistic situations as long as oxygen is enough. The VODRmax is also same as maximum […]

Bioflim MBR (BF-MBR)

Effect of attached growth on membrane performance The membrane performance of BF-MBR varies depending on experimental condition. If suspended solids are low, e.g. lower than 3-5 g/L, membrane can foul faster than in conventional MBR with higher MLSS without biocarrier. On the contrary, if MLSS of BF-MBR is higher than 3-5 g/L, most literature report […]

Membrane cleaning

Maintenance Cleaning Periodic backflushing can be performed in hollow fiber membrane processes to remove a portion of the cake layer formed on membrane surface. In practice, backflushing is performed for 10-60 seconds periodically every 10 minutes to a few hours at 1.5 to 2.0 times higher flow rates than the permeate flow rate using the […]
