Membrane bioreactor (MBR) is the combination of a membrane process like microfiltration or ultrafiltration with a biological wastewater treatment process, the activated sludge process. It is now widely used for municipal and industrial wastewater treatment.Membrane Bioreactor or MBR Sewage treatment plant is an innovative wastewater treatment method. As the name suggests, it combines two technologies membrane filtration and the biological treatment and gets rid of pollution through sedimentation, bio-reaction and membrane separation. In a Membrane Bioreactor sewage treatment plant, wastewater is first fed into a vessel filled with microorganisms that break down organic substances.The MBR Sewage Treatment system is for very small to medium sized sewage treatment plants. It combines two technologies, membrane filtration and the biological treatment.A Membrane Bioreactor or MBR Sewage treatment plant is a really good solution when it comes to treating sewage with higher organic loads and dangerous materials. Here we describe everything you need to know about this innovative technology that practically solves all water pollution issues.Membrane bioreactor (MBR) is generally a term used to define wastewater treatment processes where a perm-selective membrane, eg microfiltration or ultrafiltration, is integrated with a biological process - specifically a suspended growth bioreactor.
