Effect of Membrane Pore Size on Membrane Biofouling in Ceramic Membrane Bioreactors
Four SCMBRs were operated in parallel to investigate the treatment performance and fouling potential of ceramic membranes in MBRs. Results showed that the SCMBR was able to provide good permeate quality with COD less than 20 mg/L. The effect of the sludge characteristics such as MLSS, SMP and EPS concentrations on membrane fouling were not significant when all the systems were operated under the same condition. SCMBR with the biggest pore-sized membranes (300 nm) was the first one to experience serious fouling. The membrane surface property would affect the formation and the development of the biocake/biofilm on the membrane surface during the operation. Results indicated that the rougher the membrane surface and the smaller the biocake/biofilm porosity would result in more severe membrane fouling (i.e., 300nm pore-sized membrane).
