During use, when the feeding is completed, high-pressure fluid or gas medium can be injected into the diaphragm plate. At this time, the entire diaphragm will bulge to compress the filter cake, thereby achieving further dehydration of the filter cake, which is commonly referred to as squeeze filtration.
