“…In particular, membrane characteristics, such as membrane material, pore size, and hydrophilicity are important factors for membrane fouling because they affect interactions between the membrane surface and the mixed liquor in the bioreactor. It is believed that hydrophilic membranes allow greater membrane fouling mitigation than do hydrophobic membranes [15,16]. However, contradictory results have been reported.…”

Abstract:We aimed to investigate the relationship between membrane material and the development of membrane fouling in a membrane bioreactor (MBR) using membranes with different pore sizes and hydrophilicities. Batch filtration tests were performed using submerged single hollow fiber membrane ultrafiltration (UF) modules with different polymeric membrane materials including cellulose acetate (CA), polyethersulfone (PES), and polyvinylidene fluoride (PVDF) with activated sludge taken from a municipal wastewater treatment plant. The three UF hollow fiber membranes were prepared by a non-solvent-induced phase separation method and had similar water permeabilities and pore sizes. The results revealed that transmembrane pressure (TMP) increased more sharply for the hydrophobic PVDF membrane than for the hydrophilic CA membrane in batch filtration tests, even when membranes with similar permeabilities and pore sizes were used. PVDF hollow fiber membranes with smaller pores had greater fouling propensity than those with larger pores. In contrast, CA hollow fiber membranes showed good mitigation of membrane fouling regardless of pore size. The results obtained in this study suggest that the surface hydrophilicity and pore size of UF membranes clearly affect the fouling properties in MBR operation when using activated sludge.

“…PVDF membrane was selected in this study in view of that PVDF material is representative for the membranes used in MBRs [30]. This membrane possessed similar surface tensions and higher absolute value of zeta potential as compared to the PVDF membrane reported by Chen et al [19].…”

“…A lot of membranes with different materials have been used in MBRs applications. Among them, PVDF flat sheet membrane is a representative option for MBRs operation [38,39]. Therefore, the data of surface properties of this type of membrane were used for simulation of above-mentioned models, and also to investigate the influences of surface roughness on membrane fouling.…”
