The MBR membrane module is often used in the water treatment system. Because the MBR membrane module is expensive, it is generally not easy to replace. So we should pay attention to maintenance, and aeration is a standard maintenance method for MBR membranes.
Aeration technology refers to using aeration equipment to strengthen the air in the sewage and stir the sewage to prevent the floating objects in the output from sinking when the sewage is treated. The flue gas in the initial air can be quickly integrated into the sewage, strengthen the contact between microorganisms and organic matter, and decompose the organic matter in the oxidized sewage. Aeration generally requires the use of aeration equipment for aeration operation.
Does MBR Membrane Need Aeration?
Yes, the MBR membrane needs aeration. The facts that may cause membrane fouling are the membrane material and component properties, mixture characteristics, operating conditions, and membrane cleaning. Membrane aeration can provide activated sludge to provide the necessary amount of oxygen for metabolism and flush the MBR membrane surface, thus preventing the membrane surface from fouling and pollutants deposition.
How does the Aeration work in the MBR membrane Bioreactor?
Aeration pipes for aeration: there will be holes size of not less than 3mm, spacing 30mm on the aeration pipes. The main purpose is to flush the surface of the membrane fibers. This method can effectively prolong the stability of the MBR membrane, improve the accumulation of pollutants on the membrane surface, and increase the membrane flux.
What are the Precautions of the Aeration?
- Check the installation of the blower, and check the coolant valve switch is easy to use.
- Before opening the valve in the pipeline, vent the valve, and use the coolant to open the coolant valve.
- Before using the air blower, release the pressure, reduce the load, start the blower without load, and turn off the coolant.
- After the equipment turns off in winter, prevent the blower from being damaged by ice.
