After using the ultrafiltration membrane, it was found that the membrane often needs to be cleaned because it is stuck in the filter tank, which reminds the operator that the ultrafiltration membrane manufacturer cannot forget the habit of regular thorough cleaning during use. Problems that arise during work are reduced, and even a bad situation can occur.

After professional tests, it is safe and effective to clean up after work every day. However, due to time or other reasons, it is recommended to clean up the next day. It is recommended to clean up the next day. Operating habits.

Because every time the ultrafiltration membrane is cleaned, the impurities will be cleaned off well, and if these impurities will corrode the membrane for a long time, it should be washed with water after each cleaning, so that the membrane can be better protected. Not being corroded, increasing its service life, but also a reminder in the industry, such maintenance measures are very important at present.

When the membrane is filtered, impurities will deposit on the surface of the membrane to cause fouling, which will cause the water flux to drop in the ultrafiltration membrane. Therefore, physical and chemical cleaning should be carried out regularly and in time.

1. Backwashing means that the ultrafiltration membrane system is in the process of normal water production. When the transmembrane pressure difference of the system reaches a certain value, some manufacturers are (when 0.02MPa, we are generally 0.08MPa). Time to start automatic backwashing. The process is: smooth---reverse--in the smooth, recoil, according to the size of the system, raw water quality, design recoil and back recoil

2, chemical cleaning, this is generally when the flux of the system, attenuated by 20%, chemical cleaning, it is necessary to stop, using acid and alkali cleaning, generally first with the agent soak for several hours (depending on the pollution situation) , in the loop for a few hours.

3. There are also scattered chemical cleaning, and so on.
