For example, a cleaning process in which clean water is injected under pressure from the discharge side of the microfilter allows regeneration of the microfilter to some extent, but this requires injecting high-pressure water over a very long period of time. There are drawbacks. In addition,
This washing process cannot completely remove turbidity particles trapped deep within the pores of the microfilter, and it is also possible to decompose bacterial colonies on the surface of the microfilter.
