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 کاملSewage Sludge-derived Adsorbents for H2s Removal
Various methods have been used to dispose of or utilize municipal sewage sludge (1), including incineration, landfilling, road surfacing, conversion to fertilizer, compression into building blocks, and carbonization (1-4). Since 1976 several patents have been issued on carbonization of sewage sludge and various applications of the final materials (4-7). Carbonization of sludge in the presence o...
متن کاملMicrobial 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...
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 کاملSewage Sludge-derived Materials as Adsorbents of So2
Adsorption of sulfur dioxide on carbonaceous materials has been extensively studied (1-18). Activated carbon and activated carbon fibers have been found to be efficient adsorbents for the low temperature removal of SO2. It is believed that sulfur dioxide is adsorbed with two adsorption energies on activated carbons (3-12). The low energy, about 50 kJ/mol, corresponds to weak physical adsorption...
