Membrane Bioreactor Technology for Wastewater Treatment
Membrane bioreactor (MBR) system 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 degrade 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 reuse. MBR methods offer several advantages, 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.
