1. Improve the filter cake degree, reduce the water content of the filter cake, and press the filter cake after static filtration by diaphragm press, so as to rearrange the structure of the filter cake and increase the density, so as to replace part of the water and improve the dryness.
2. Save the consumption of operating power. In the later stage of filtration, the flow is small, the pressure is high, and the power consumed by the feed pump is also very high. The diaphragm pressing function is used to complete this process in a very short time, saving power consumption.
3. The filter plate is molded from reinforced polypropylene. The diaphragm and polypropylene plate are embedded together, which is firm, not easy to fall off and long service life.
