Abstract
AbstractTextile wastewater is typical industrial wastewater that can lead to serious environmental problems if discharged without treatment. Thus, it is meaningful for developing the treatment processes for textile wastewater. At present, many common biological methods are available for the textile wastewater treatment, including activated sludge, granular sludge, membrane bioreactors (MBR), the up-flow anaerobic sludge blanket, sequential batch reactors, and so on. This chapter focuses on the use of MBRs for treating textile wastewater. We reviewed key parameters that had effects on the treatment performance, the enhanced strategies for MBRs treatment and the application of MBRs in pilot-scale and full-scale. With the optimal key parameters, pollutant removal performance could obtain high level with the removal efficiencies of more than 90% for organic matters, dye, and total nitrogen, and 100% for suspended solid. Moreover, some typical membrane cleaning methods were introduced to address the membrane fouling. For achieving a sustainable flux operation, anti-fouling strategies for operational MBRs were explained. Besides, studies related to the microbial community in the biological treatment of textile wastewater were described, and the status of the analysis of microorganisms in the treatment of textile wastewater with MBRs was discussed.KeywordsMembrane bioreactorAnaerobic membrane bioreactorTextile WastewaterBiodegradationDye treatmentMembrane filtrationMembrane foulingAnti-fouling strategyMicrobial community
