A Detailed Overview of Membrane Bioreactor (MBR) Technology
MBR technology involves the use of an advanced biological treatment process that is coupled with membrane filtration. MBR membrane bioreactors provide better quality effluent, have a high rate of removal efficiency, and occupy less space when compared to conventional wastewater technologies. This paper aims to discuss MBR technology: the main components, benefits, uses in various fields, and development trends. Components of MBR Membrane Bioreactor 1. Biological Treatment Unit The biological treatment unit therefore resembles the familiar activated sludge systems. It comprises microorganisms that break down solids that are suspended in the wastewater. The primary components include: Aeration Tank: Supplies oxygen to promote aerobic bacterial growth. Biomass (Mixed Liquor Suspended Solids, MLSS): Bacteria and other organisms that break up organic compounds. 2. Membrane Filtration Unit The membrane filtration unit is where the water is separated from the mixed liquor. It consists of:
