The Membrane Bioreactor (MBR) is an advanced wastewater treatment technology that combines biological treatment processes with membrane filtration. It is widely adopted in municipal, industrial, and commercial sectors for efficient sewage and effluent management, offering superior effluent quality and compact design compared to traditional methods.
