The MBR membrane is mainly used for precision filtration in the water treatment system. Damaged membrane components will not only reduce the filtration accuracy of the MBR system but also affect the filtration of the entire sewage treatment system. Frequent membrane replacement not only increases costs but also reduces the efficiency of water treatment. Therefore, we must pay attention to the operations, reduce the probability of damage to the membrane module, and maintain regularly. What is the service life of the MBR membrane, and what is the maintenance method of the membrane module?
What is the Service Life of the MBR Membrane?
The service life of the MBR membrane is not fixed and has a great relationship with the specific usage in actual operation. The average service life of MBR membranes is 2-4 years, while the service life of SPERTA membranes is longer. Generally speaking, if the water quality is normal, the operation in all aspects conforms to the specifications, and the use, cleaning, maintenance, maintenance, and other aspects are as required, the service life will be longer.
We must do regular maintenance work to extend the MBR membrane’s lifespan and reduce the component’s replacement.
How to Maintenance the MBR Membrane?
- When the MBR membrane operates, the backwash pressure cannot exceed 0.15MPa. If this pressure is exceeded, it may damage the membrane.
- We should operate the suction pump intermittently. That is to say, it needs to be stopped after running for a period of time, and we should restart the system after stopping for a while. It cannot work continuously for 24 hours, and it is forbidden to run for a long time.
- We should maintain sufficient aeration in the MBR membrane tank. In the normal operation process, avoiding the blockage of the aeration pipe is necessary. We cannot shut down the blower for the MBR tank at will. Shutting down the blower without authorization will easily cause the blockage of the membrane.
- We should keep the sludge concentration in the membrane tank within the range of 20%-50%. If the sludge concentration is too high, it will block the membrane fibers. When the sludge concentration exceeds the standard line, the sludge should be discharged out of the membrane tank in time.
The above is the information about the service life of the MBR membrane and how to maintenance the MBR Membrane. If you still have related questions about the membrane bioreactor, please feel free to contact SPERTA.
