MABR Membrane Aerated Biofilm Reactor


‌Working Principle of MABR Membrane Aerated Biofilm Reactor




MABR (Membrane Aerated Biofilm Reactor) utilizes a gas-permeable membrane for aeration and oxygen supply. Dissolved oxygen diffuses through the membrane into the biofilm, providing the necessary oxygen for microorganisms to metabolize and oxidize pollutants in wastewater. The gas-permeable membrane also serves as a substrate for the biofilm, supporting microbial growth. By employing a non-bubbling aeration method, MABR achieves nearly 100% oxygen transfer efficiency, making it particularly advantageous for treating high-concentration wastewater.




Key Features:






High Oxygen Transfer Efficiency: The non-bubbling aeration method of MABR allows for nearly 100% oxygen transfer efficiency, significantly improving treatment efficiency.

Efficient Oxygen Mass Transfer Rate: The membrane’s structural design optimizes the oxygen mass transfer rate, making it suitable for high-concentration wastewater treatment.


Large Biofilm Surface Area: A larger biofilm surface area enhances the removal of pollutants from wastewater.


Inner and Outer Layered Structure: MABR features a unique inner and outer layered biofilm structure, adaptable to various wastewater treatment needs.

Semi-Hydrophobic Membrane Material: Made from high-performance polymer composite materials, the hollow fiber oxygen-permeable membrane has excellent biocompatibility, high strength, and efficient oxygenation.





Applications:





Wastewater Treatment: Effective for municipal and domestic wastewater treatment, as well as industrial wastewater, especially suitable for high-concentration wastewater.

Sponge City Construction: Used for rapid and efficient oxygenation and purification of lakes, landscape water bodies, and rivers, including black and odorous water bodies and Class V water bodies.

Environmental Remediation: Improves water quality by removing organic matter and nutrients, adaptable to various water quality conditions.
