Waste Water Treatment Using Membrane Bioreactor: A Brief Review

Abstract

The exponential rise in human population has fueled expansion in a wide range of industries. Today, a reliable water supply and the ability to process wastewater efficiently to generate high-quality wastewater are considered necessities. By removing both organic and inorganic particles, membrane bioreactors (MBRs), a biological unit for wastewater treatment, can be used to simultaneously address these two urgent issues. MBR facilities have several advantages over more conventional methods like activated sludge because of the combination of the biological process with membrane filtration. They are widely employed in the industrial and municipal wastewater treatment industries. We'll go through the fundamentals of MBR plants in this survey, from their core ideas to the most recent advancements in each component.  After thoroughly investigating the features of the bioreactor treatment process, the parameters of the membrane separation procedure are investigated. Both the fouling phenomenon and modern methods for reducing fouling are presented in detail. Fouling is a serious problem that prevents MBRs from being used more frequently. Efforts from a variety of innovative MBR processes are summarised. Issues that now exist and future research projects that could help make MBRs more practically applicable on a larger scale are proposed.
