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 کاملEnhanced Biological Phosphorus Removal within Membrane Bioreactors
Several Membrane Bioreactor (MBR) facilities have been constructed with the intent of providing Enhanced Biological Phosphorus Removal (EBPR), and several additional such plants are being designed and constructed. Full-scale plant information is now available for process designers to better understand the unique design and operating issues associated with the incorporation of EBPR designs in MB...
متن کاملComparison Study between Integrated Fixed Film Activated Sludge (ifas), Membrane Bioreactor (mbr) and Conventional Activated Sludge (as) Processes
Comparison study is required to evaluate the treatment efficiency of three alternative secondary treatment processes. These Processes are Integrated Fixed-film Activated Sludge (IFAS), Membrane Bioreactor (MBR) and Conventional Activated Sludge (AS). This study is required for a new wastewater treatment plant. The characteristics of the influent domestic wastewater for the proposed plant were m...

متن کاملEffects of integrated fixed film activated sludge media on activated sludge settling in biological nutrient removal systems.
Integrated fixed film activated sludge (IFAS) is an increasingly popular modification of conventional activated sludge, consisting of the addition of solid media to bioreactors to create hybrid attached/suspended growth systems. While the benefits of this technology for improvement of nitrification and other functions are well-demonstrated, little is known about its effects on biomass settleabi...
