Degradation of a model azo dye in submerged anaerobic membrane bioreactor (SAMBR) operated with powdered activated carbon (PAC).
This work investigated the anaerobic degradation of the model azo dye Remazol Yellow Gold RNL in an upflow anaerobic sludge blanket reactor (UASB) and two submerged anaerobic membrane (SAMBR) bioreactors, one of which (SAMBR-1) was operated with powdered activated carbon (PAC) in its interior. The reactors were operated at 35 °C with a hydraulic retention time of 24 h in three operational phase...
متن کاملSimulating the soluble microbial products in a membrane bioreactor system and their impact on membrane fouling
Introduction MBRs (membrane bioreactors) are a recent innovation of the activated sludge process, which eliminates many constraints associated with the traditional gravity settling. Nevertheless, it suffer membrane fouling. The colloidal and macromolecular fraction of MBR sludge has been reported as the main foulant of MBR systems. SMP can be classified into BAP (biomass associated products) an...
متن کاملModeling of extracellular polymeric substances and soluble microbial products production in a submerged membrane bioreactor at various SRTs.
Extracelluar polymeric substances (EPSs) and soluble microbial products (SMPs) produced by microbial cultures involved in membrane biofouling have been widely investigated. A mathematical model of EPS and SMP formation and degradation was established based on the activated sludge model no. 1 (ASM1) and was applied to the membrane bioreactor sludge with different sludge retention times (SRTs). T...
متن کاملDecolourisation of textile wastewater in a submerged anaerobic membrane bioreactor.
Azo dye decolourisation can be easily achieved by biological reduction under anaerobic conditions. The aim of this study was to evaluate the applicability of submerged anaerobic membrane bioreactors (SAMBRs) for the decolourisation of dyeing wastewater containing azo dyes. The reactive orange 16 was used as model of an azo dye. The results demonstrated that very high decolourisation (higher tha...
متن کاملTreatment of Textile Effluent Using Submerged Membrane Bioreactor
Climate change makes people to be aware about the environmental pollutions in aspect of Air, Water and Soil components. The environmentally aware countries have forced the other countries to implement the stringent effluent standards for disposal into water stream / water bodies. Hence, modern technology like the application of membrane separation (Micro or Ultra filtration) technique with biol...
