PAC addition on immersed ultrafiltration membrane for treatment of taste and odor
摘要
Abstract
Hybrid processes of conventional treatment and PAC addition on immersed ultrafiltration membrane was evaluated for the treatment of taste and odor in algal-rich water simulated. The results confirm that in the immersed ultrafiltration membrane bioreactor PAC has sufficient adsorption and long-term biodegradation of dissolved organic materials which cannot be filtrated by ultrafiltration membrane alone. UF-PAC processes could intensify the conventional treatment. Through the advanced treatment of UF-PAC, the algae cells are all removed and the average removal efficiencies of DOC, UV254 and CODmn increase by 19.6%, 30.0% and 28.3% compared with the conventional treatments, respectively. And 2-MIB and geosmin in effluent both fall below the odor threshold, which guarantee the effluent quality. Membrane fouling was mitigated by both conventional treatment and PAC in the membrane bioreactor the transmembrane pressure increases by only 9 kPa in 30 d.关键词
