Abstract
This study demonstrated the importance, process, activation and applications of Membrane in bioreactor to treat the waste water. Membrane Bioreactor (MBR) process consists of a biological reactor integrated with membranes that combine clarification and filtration of an activated sludge process into a simplified, single step process. Operating as an MBR allows conventional activated sludge plants to become single step processes, which produce high quality effluent potentially suitable for reuse. Application of MBR technology for industrial wastewater treatment has also gained attention because of the robustness of the process. Theoretically, maintenance of long SRT in MBR is in favor of the retention and development of special microorganisms, which may lead to better removal of refractory organic matter and make the system more robust to load variations and toxic shocks. Literature suggested the conceptual expectation of enhanced biodegradation of hardly biodegradable compounds in MBR does not often come true. Improved biodegradation to certain extent has been reported in a few studies; however the underlying factors leading to such improvement still remains to be elucidated. This is comprehensive review of the studies dealing with recalcitrant industrial wastewater treatment by MBR, and casts light on the strategies to achieve enhanced biodegradation of hardly biodegradable industrial pollutants in MBR.

It is important to highlight that industrial wastewater may heavily influence the microbial selection process within an MBR because of the presence of refractory compounds [11]; and the efficiency in the removal of the organic load depends on the type of industrial process that has been implemented and on the quantity of non-biodegradable compounds
The applications of MBR are necessary for long biological solids retention times, physical retention and subsequent hydrolysis to achieve the biological degradation of pollutants

It is important to highlight that industrial wastewater may heavily influence the microbial selection process within an MBR because of the presence of refractory compounds [11]; and the efficiency in the removal of the organic load depends on the type of industrial process that has been implemented and on the quantity of non-biodegradable compounds. This research addresses this question by providing a comprehensive review of the studies dealing with recalcitrant industrial wastewater treatment by MBR and offers unique insights into this matter
