Membrane bioreactors (MBRs) represent a prominent technology in the field of wastewater treatment. These systems integrate biological treatment processes with membrane filtration, offering a robust solution for removing contaminants from wastewater and producing high-quality effluent. MBRs integrate a bioreactor vessel where microorganisms consume organic matter, followed by a membrane module that effectively filters suspended solids and microorganisms from the treated water. As a result of their high treatment efficiency and ability to produce effluent suitable for reuse or discharge into sensitive environments, MBRs are increasingly in municipal, industrial, and agricultural settings.

• MBRs offer a versatile approach for treating various types of wastewater, such as municipal sewage, industrial effluents, and agricultural runoff.
• Their compact size and modular design make them suitable for installation in diverse locations, including areas with limited space.
• Additionally, MBRs are highly energy-efficient compared to conventional treatment methods, reducing operational costs and environmental impact.
