Membrane bioreactor (MBR) system is a sophisticated method of wastewater treatment that combines conventional biological treatment with membrane filtration. MBR plants operate by cultivating microorganisms in an aerobic environment within a reactor, where they break down 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 recycling. MBR processes offer several advantages, including high removal efficiency, small footprint, and the ability to produce treated water that meets stringent discharge requirements.
MBR systems are increasingly being adopted worldwide for a range of applications, such as municipal wastewater treatment, industrial effluent processing, and even drinking water production.
