A powdered activated carbon-dynamic membrane bioreactor (PAC-DMBR) was developed and used to treat domestic wastewater by dosing with 3g/L PAC. The experimental results were compared with those of a control DMBR to investigate the filtration performance and various properties of the dynamic membrane (DM) layer. One flat-sheet DM module made of nylon mesh (pore size 75μm) was used for effluent production...
Three PAC-DMBRs were developed for wastewater treatment under different PAC dosages with biomass concentrations averaged at 2.5, 3.5 and 5.0g/L. The DMBRs could be continuously operated at 40–100L/m2h, while higher fluxes were obtained within the PAC-DMBRs with hydraulic retention times varying in 4–10h. A dose of 1g/L PAC brought about obvious improvement in the sludge particle size distribution,...
