Fouling mitigation through maghemite particles in membrane bioreactor

Year: 2018

Type: conference-paper

Abstract: In this study, there were two parallel membrane bioreactors (MBR) were operated to verify the influence of maghemite addition on membrane fouling in municipal wastewater treatment at maghemite addition of 0.54 gL -1 .Mesoporous maghemite particles was prepared via hydrothermal method.The average COD removal was 95% involving in effluent with COD ranging from 12-55 mg/L.The turbidity of both MBR effluent values ranged from 0.4 to 1.5 NTU.The feed and operating conditions were similar in both MBR, and COD, turbidity, TMP, flow rate, SVI, MLSS and EPS were monitored over 60-day period.Maghemite was able to adsorp the proteins and after maghemite addition, the rate of membrane fouling was decreased.Detailed studies on the effect of maghemite addition in MBR indicated that maghemite dosage of 0.54 gL -1 was able to reduce fouling in membrane bioreactors.
