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...
متن کاملInfluence of membrane pore size and material on membrane fouling in membrane bioreactors operated under different sludge retention time
Membrane bioreactors (MBRs) have several advantages such as high-quality effluent, small footprint and less sludge production over conventional activated sludge systems, and are therefore considered to be a promising technology for future wastewater treatment. For wider use of MBRs, however, high-energy consumption in the operation of MBRs, mainly attributed to membrane fouling, needs to be add...
متن کاملThe Effect of Membrane Material and Surface Pore Size on the Fouling Properties of Submerged Membranes
We aimed to investigate the relationship between membrane material and the development of membrane fouling in a membrane bioreactor (MBR) using membranes with different pore sizes and hydrophilicities. Batch filtration tests were performed using submerged single hollow fiber membrane ultrafiltration (UF) modules with different polymeric membrane materials including cellulose acetate (CA), polye...

متن کاملEffects of salinity on the characteristics of biomass and membrane fouling in membrane bioreactors.
This study investigated the effects of high salinity on the performance and membrane fouling of membrane bioreactor (MBR) with saline wastewater. Synthetic wastewaters containing 5-20 g/L salts (NaCl) were treated in identical lab-scale (7 L) MBRs monitoring removals of dissolved organic carbon (DOC) and ammonia. Increase in salt concentrations did not significantly change the removal efficienc...
