MBR Water Treatment System

MBR Water Treatment System Working Principle

After the sewage enters the bioreactor, microorganisms decompose and metabolize the pollutants. The mixed liquid then enters the membrane component. Under pressure or suction, water passes through the membrane pores to become treated effluent. The membrane retains microorganisms, macromolecular organic matter, and other solids, which are returned to the bioreactor to continue participating in the reaction.

MBR Water Treatment System Composition

• Membrane Separation Component: The core of the MBR system (often referred to as the mbr process in water treatment), it achieves solid–liquid separation. Common forms include plate and frame, spiral roll, circular tube, hollow fiber, and capillary types. The term mbr full form in water treatment refers to “Membrane Bioreactor,” which highlights the combination of membrane filtration and biological treatment.

• Bioreactor: Provides a habitat for microorganisms to degrade and remove pollutants in the wastewater.

MBR Water Treatment System Advantages

• High - Quality and Stable Effluent: Suspended solids and turbidity are nearly zero, with significant removal of bacteria and viruses.

• Low Sludge Production: Operates at high volumetric load and low sludge load, potentially achieving zero sludge discharge.

• Small Footprint: High microbial concentration in the bioreactor, eliminating the need for a secondary sedimentation tank and saving space.

• Effective Removal of Ammonia Nitrogen and Refractory Organics: Captures slow - growing microorganisms like nitrifying bacteria, enhancing degradation of refractory organics.

• Easy Operation and Management: Complete separation of hydraulic and sludge retention times, with easy automation.

• Easy Integration with Traditional Processes: Can be used as a advanced treatment unit in traditional wastewater treatment processes.
