[0002] Ceramic nanofiltration membrane is a functional semi-permeable membrane that allows solvent molecules or certain low molecular weight solutes or low-valent ions to pass through. After use, some impurities will adhere to the ceramic nanofiltration membrane, so it is necessary to clean the impurities inside and on the surface of the ceramic nanofiltration membrane;

[0003] Chinese utility model patent CN218688188U discloses a cleaning mechanism for impurities on the surface of a ceramic nanofiltration membrane.
