This experiment used A/O industrial filter cloth self-forming dynamic membrane reactor to treat campus domestic sewage, COD removal rate of the effluent was 91%, NH3-N and TN removal rate of the effluent was 92.4% and 88.1% respectively, the average turbidity of the effluent was 2.31NTU. The test results showed that the A/O industrial filter cloth self-forming dynamic membrane reactor had good effect...
A submerged rotating membrane bioreactor (SRMBR), with a rotatable, rounded, flat-sheet Poly(vinyldiene fluoride) (PVDF) membrane module fixed on the hollow axes and moved by an electromotor, was used for wastewater reclamation. The efficiencies of SRMBR, the effects of operation parameters on membrane permeate flux were studied. It was found that the effluent COD became stable and lower than 20 mg/L...
In order to reveal the effect of powdered activated carbon (PAC) pretreatment on Ultrafiltration (UF) membrane filtration performance, PAC-UF system treating Yangtze River water was studied. The results showed: 41.46% of UV254, 31.94% of CODMn, 38.44% of DOC, and 54.69% of THMFP were removed in the PAC-UF system. VHA and CHA could be removed effectively by PAC, which decreased risks of membrane fouling...
