The solids collected by the ceramic filter accumulate outside or inside the filter layer, blocking the pores of the filter, and the filtration capacity will decrease. This clogged state can be expressed in several forms, such as collecting solids on the surface; solids entering the inner layer of the filter; and solids accumulated on the surface to form a rough surface layer (as if it were a filter layer). Capacity is gradually decreasing, but the degree of decline is different.
