To reduce the membrane fouling in an immersed membrane bioreactor (MBR) during the treatment of food wastewater, an additional continuous stirring was introduced. The results showed that both a better membrane performance and a higher degradation efficiency for food wastewater were obtained. The membrane contributed mostly in concentrating the activated sludge. The bioreactor ensured the degrad...

A continuous compact membrane bioreactor consisted of ceramic-supported graphene oxide (CSGoM) was implemented for the first time anaerobic biodecolorization monoazo Acid Orange 7 (AO7), diazo Reactive Black 5 (RB5), and triazo Direct Blue 71 (DB71) solutions, showing excellent decolorization potential. The prepared by vacuum filtration various solutions using a UF ceramic flat element. efficie...

Know days, pollution made by the wastewater in rivers and other water body’s is one of the main concerns of environmental engineers. Membrane bioreactors are one of the earliest methods for treating swage and also to produce water that is acceptable for reuse purposes. The term membrane bioreactor expresses a combination of activated sludge and membrane separation processes. The need to process...

This paper presents the results of an investigation on the effects of concentration of cations on activated sludge properties and membrane fouling in submerge membrane bioreactors. The working volume of the experimental setup was two liters. The cellulose acetate membrane was immersed in the bioreactor. The flocculability, settling properties and fouling propensity of activated sludge was measu...

This study investigated the effects of salinity increase on bacterial community structure in a membrane bioreactor (MBR) for wastewater treatment. The influent salt loading was increased gradually to simulate salinity build-up in the bioreactor during the operation of a high retention-membrane bioreactor (HR-MBR). Bacterial community diversity and structure were analyzed using 454 pyrosequencin...
