Filtration technology has undergone innovation and upgrading and has become an indispensable and important technology in modern industry.

[0003] Traditional membrane filtration equipment generally uses a pump to give the system enough pressure, and the filtrate is discharged from the equipment through the filter cake layer formed by the filter medium. As the filtration time continues to accumulate, the filter cake becomes thicker and thicker, and the filter holes become smaller and smaller. In this way, the filtrate cannot pass through the medium, and the filter cloth must be replaced in time to proceed to the next cycle.
