Abstract
In the laboratory-scale research, anoxic membrane bioreactor (MBR), in which a membrane is submerged in the second anoxic reactor, and aerobic MBR, where a membrane is installed in the aerobic reactor, were operated simultaneously to observe advantages and disadvantages of the 4-stage anoxic MBR process. The advantages observed were as follows: (1) nitrogen concentration in effluent (5.2mgN/L) superior to that in aerobic MBR (7.1mgN/L) and (2) efficient utilization of carbon source to remove nutrients (2.46g SCODutilized/g [N-denitrified+P-released]). In contrast, the disadvantages of this process were as follows: (1) relatively higher phosphorus concentration in effluent (0.9mg/L) than in aerobic MBR (0.5mg P/L), (2) 20% lower membrane permeability, and (3) 25% lower sludge settleability.
