Membrane Bioreactors (MBRs) combine biological treatment processes with membrane filtration to treat wastewater. They use a biological process, typically involving bacteria, to break down organic matter, while membranes filter out solids and pathogens, resulting in cleaner effluent. MBRs are effective in removing contaminants and can produce high-quality water suitable for reuse. These systems are often used in municipal and industrial wastewater treatment facilities. MBRs offer advantages such as a smaller footprint compared to traditional methods and the ability to operate at higher concentrations of solids. They are increasingly popular due to their efficiency and effectiveness in meeting stringent environmental regulations.
