“…However, synergetic effects of activated carbon adsorption, biodegradation and membrane filtration leads to better permeate quality with regard to recalcistrant pollutants [7]. Therefore, in more recent studies, addition of activated carbon has been studied for the removal of pharmaceuticals [212][213][214] and water reuse [215]. At high dosage of 1 g/L of PAC, the removal efficiencies of sulfamethoxazole and carbamazepine increased from 64% to 82% and from below 20% to 92%, respectively [212].…”

Membrane bioreactor (MBR) technology is considered a well-established, mature technology with many full-scale plants around the world treating municipal and industrial wastewater. However, membrane fouling and energy consumption still remain serious obstacles and challenges in the wider spread of the MBR technology. Therefore, considerable research and development efforts are still underway. Recent developments are primarily focused on aspects related to energy reduction, fouling control and novel configurations for enhanced process performance. This review addresses the recent work on the above mentioned aspects and it discusses the overall life cycle of MBRs and the market prospects for MBR technology. Novel MBR configurations and integrations with other technologies are also reviewed. Finally, the challenges that need to be addressed in order to facilitate market penetration of MBR technology are highlighted.

“…Meanwhile, a new microbial community can be generated, which can affect the formation of metabolic products. Since most of the pollutants especially dissolved organic matter (DOM) are removed by adsorption biodegradation and the bacteria are intercepted within the bioreactor by membrane separation, an excellent effluent can be gained by PAC-MBR systems (Ma et al 2014;Satyawali and Balakrishnan 2009). In theory, the reclaimed water produced by PAC-MBR is suitable for various reuse application; however, postdisinfection of the PAC-MBR effluents is essential to guarantee hygienic safety of water reuse and meet legislation requirements.…”

In this study, a hybrid powdered activated carbon-membrane bioreactor (PAC-MBR) system was used to treat municipal wastewater in northern China intended for recycle. In order to control microbiological hazards in PAC-MBR effluent, chloramine was chosen as the disinfectant which could reduce the disinfection by-product yields. Effects of reaction time, chloramines dose, pH value, and bromide ion concentration on trihalomethanes (THMs) formation and speciation during chloramination of the reclaimed effluent were investigated. Study results indicated that the yield of total THMs (TTHM) increased at higher reaction time and chloramines dose. The trend of growth showed that slow reacting precursors were the main components of dissolved organic matter (DOM) in PAC-MBR effluent. THMs formation potential of PAC-MBR effluent achieved the maximum at chloramines dosage of 20 mg/L. Meanwhile, THMs formation was enhanced evidently under alkaline conditions. The yields of THMs species were in following order: CHCl3 > CHBrCl2 > CHBr2Cl > CHBr3, although in different reaction time, chloramines dose, and pH value. Furthermore, the formation of Br-THMs was promoted by the increasing concentration of bromide ion.

“…Prolonging the SRT, the effluent DOM became more hydrophilic which favored the 23 removal of high molecular weight (> 5 kDa) DOM mainly due to biodegradation by 24 well-acclimatized microorganisms (Ma et al, 2014 flocs located close to the membrane surface which are exposed to high shear owing to showed that the capillary suction time is also subject to the type of the PAC used.…”
