The special material and structure of the honeycomb ceramic filter determine its characteristics. First, it has good strength, wear and corrosion resistance, and long service life. At the same time, because of its good strength, no deformation of micropores, and stable technical indicators without fluctuation; The pores are small (about 1.5 microns), the capillary action is strong, and the filtrate is automatically sucked into the micropores. The function of the vacuum pump is to discharge the filtrate to save energy; (up to 0.098Mpa) filter cake moisture is low, and the filter utilization coefficient is high; also because of the small pores, the suspended solids content in the filtrate is low, and the filtrate is clear, which can be used for on-site water circulation to prevent environmental pollution and save water resources.
