The effect of aeration mode on the operational effectiveness and membrane bioreactors for greywater treatment and membrane fouling

This study aims to investigated the effect of aeration mode on membrane bioreactors (MBRs) using a self-designed integrated hollow fiber MBR and flat sheet organic for rural greywater treatment. The pollutant removal efficiency, characteristics activated sludge mixed liquor, mechanisms fouling were systematically analyzed under intermittent continuous modes. results indicate that permeability MBRs in is higher than when operating at same rate. Due extracellular polymeric substance (EPS) soluble microbial product (SMP) concentrations. rates TN TP by both those due difference environment. Compared flat-sheet membrane, hollow-fiber surface was more likely form biofilms, which cause biological fouling.The relative abundance Thermomonas showed positive correlation with EPS concentration, indicating participates synthesis. provides theoretical basis evaluating influence modes MBRs,and would be useful guide better control treatment greywater.
