Effluent standards have become more and more stringent due to an increase in awareness about environmental impacts on both continuous and intermittent polluting discharge. For that, a high efficient waste water treatment plants are needed to be designed. Membrane bioreactor (MBR) can be good solution to cope with such issues. MBR systems respects the conventional activated sludge process which use microorganisms for degradation of organic pollutants and requires aeration as well as reduced foot print and sludge production through maintaining a high biomass concentration in the bio reactor. The present work elucidates the recent patents and critically reviews the advancement in MBR process, which can be helpful to designer. It was found that the behavior of aeration device, mixed liquor suspended solids (MLSS) concentration, flux enhancer and handling of sludge plays an important role in the performance of MBR process.
由于人们对连续和间歇污染排放对环境影响的认识不断提高，废水排放标准变得越来越严格。为此，需要设计高效的污水处理厂。膜生物反应器（MBR）可能是应对此类问题的良好解决方案。MBR系统遵循传统的活性污泥工艺，该工艺利用微生物降解有机污染物，需要曝气，并且通过在生物反应器中保持高生物量浓度来减少占地面积和污泥产量。本工作阐述了最近的专利，并对MBR工艺的进展进行了批判性综述，这对设计者可能会有所帮助。研究发现，曝气装置的行为、混合液悬浮固体（MLSS）浓度、通量增强剂和污泥处理在MBR工艺的性能中起着重要作用。
