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 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...
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 کاملNanofiltration of synthetic and industrial dye baths: Influence of temperature on rejection and membrane fouling
Nanofiltration (NF) has become a widely accepted process not only for producing drinking water but also for recovering wastewater in industrial processes or removing pollutants from industrial wastewater effluent. In the textile industry, the treatment of various dye baths with NF at room temperature have already been studied and was found feasible at lab-scale and pilot scale. The aim of this ...
