Advantages of MBRs Over Conventional Biological Treatment Method
1. What is MBR (Membrane Bioreactor)? The MBR (Membrane Bioreactor) which was first used in the late 1960s made a revolution in the wastewater industry in the early 1990s by combining membrane filtration with a biological treatment solution to treat wastewater. It's been commonly used since then and can be seen widely practiced in the design of both new and old wastewater treatment facilities. ...
