Membrane bioreactor (MBR) technology is a sophisticated method of wastewater treatment that combines conventional biological treatment with membrane filtration. MBR systems operate by cultivating microorganisms in an aerobic environment within a reactor, where they degrade organic contaminants in the wastewater. The treated water then passes through a semipermeable membrane, which effectively removes suspended solids and remaining contaminants, producing high-quality effluent suitable for reuse. MBR methods offer several benefits, including high removal efficiency, small footprint, and the ability to produce treated water that meets stringent discharge requirements.
MBR units are increasingly being utilized worldwide for a range of applications, such as municipal wastewater treatment, industrial effluent processing, and even drinking water production.
