A Membrane Bioreactor (MBR) is a wastewater treatment technology that combines biological treatment and membrane filtration. It uses microorganisms to break down organic matter while a membrane separates the treated water from the biomass. This process results in high-quality effluent suitable for reuse or discharge. MBRs are commonly used in various applications, including municipal wastewater treatment and industrial processes. They offer advantages such as reduced footprint, improved effluent quality, and the ability to handle varying loads. The technology is gaining popularity due to its efficiency and effectiveness in managing water resources, especially in urban areas.
