Membrane Fouling Alleviation Characteristics of Sludge/Water Pre-separation MBR
泥水预分离MBR膜污染缓减效能研究

A long-term operation was conducted to investigate the alleviation of membrane fouling by sludge/water pre-separation membrane bioreactor (S/W-MBR). The variation of trans-membrane pressure (TMP),concentration of sludge and extracellular polymeric substances (EPS) on S/W-MBR and submerged membrane bioreactor (SMBR) was also studied. The results showed that the sludge concentration in S/W-MBR was basically identical with that of SMBR's biotic area,while the sludge concentration was significantly decreased in...
