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