Effect of Concentration of Cations on Activated Sludge Properties and Membrane Fouling in Membrane Bioreactors for Wastewater Treatment

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...

Combined Three Mechanisms Models for Membrane Fouling during Microfiltration

Five new mathematical triple fouling models were developed to explore the flux decline behavior during the microfiltration. The first model was developed by the assumption of the successive effects of standard mechanism, intermediate pore blockage and cake formation by using the standard blocking flux expression in the model calculations. The second and third models also obtained by the success...

Effects of Fine Particles on Performance of Enhanced Backwash for Fouling Reduction in Anaerobic Membrane Bioreactors

Anaerobic membrane bioreactor (AnMBR) can produce high-quality effluents through effective solid-liquid separation using microfiltration. During the operation of the membrane bioreactor system, membrane fouling is one of the main problems. Several models have been proposed to understand the mechanisms of fouling of the membrane. Usually, cake formation and pore blocking are found to be the main...

Microbial Relevant Fouling in Membrane Bioreactors: Influencing Factors, Characterization, and Fouling Control

Microorganisms in membrane bioreactors (MBRs) play important roles on degradation of organic/inorganic substances in wastewaters, while microbial deposition/growth and microbial product accumulation on membranes potentially induce membrane fouling. Generally, there is a need to characterize membrane foulants and to determine their relations to the evolution of membrane fouling in order to ident...

Anaerobic Membrane Bioreactors (AnMBR) for Wastewater Treatment

This paper focuses on the recent research in the development of anaerobic membrane bioreactors in wastewater treatment. Anaerobic wastewater treatment technology is gaining increasing attention due to its capacity to convert wastewater BODs to usable biogas with relatively low energy consumption. The anaerobic membrane bioreactor (AnMBR), which is a combination of the anaerobic biological waste...
