Membrane fouling, which is caused by deposition or adsorption of foulants on surface or within membrane pores, still remains a bottleneck that hampers the widespread application of MBR technology for wastewater treatment  . Recently membrane surface coating has proved to be a useful method in water treatment to improve surface hydrophilicity of membranes to obtain high water flux and to reduce fouling . Due to its anti-fouling properties, TiO2 is well known as a membrane surface coating material in water applications. In this study, thin film of same thickness of TiO2 was deposited over UF alumina membrane surfaces (average surface pore size = 80 nm) by sputtering, electron-beam deposition and hydrothermal growth. Basic objective of this research was to conduct a comparative study of fouling inhibition performance of these modified membranes in a lab-scale anaerobic membrane bioreactor (AnMBR) for wastewater treatment.
BSA adsorption and clean water permeability tests were conducted for virgin and modified membranes. Thorough material characterization of virgin & all modified membranes was done by contact angle measurement, AFM, SEM and TEM analysis. When all of these modified membranes were applied in constant-flux AnMBR filtration system, they showed...
