A membrane bioreactor (MBR) is a type of wastewater treatment system that combines biological treatment and a membrane filtration process. Some common synonyms for the term MBR include "membrane activated sludge process," "membrane biofiltration," and "membrane separation activated sludge system." Additionally, the MBR system can be referred to as a "closed-circuit filtration system," "advanced wastewater treatment," or "membrane filtration reactor." The use of MBR technology has become increasingly popular in recent years due to its high-quality effluent and smaller footprint compared to other wastewater treatment systems. With the growing demand for sustainable and efficient wastewater treatment solutions, the MBR system is a promising option to meet these needs.
