Basic operation involves generating a slurry of precoat matter with either water or processed liquid. The slurry is then circulated through the filter back to the procoat skid until the appropriate depth of precoat is achieved.
Particles up to 1 μm fineness can be filtered out depending on the type of filter aid. Small quantities of filter aids can be added continuously when filtering heavily contaminated liquids in order to maintain the porosity of the filter cake.
If the maximum permissible pressure is reached during increasing contamination of the filter cake, the filter shall be cleaned by regeneration. Discharge and back flushing occur simultaneously. The feed pump is switched off if this pressure is exceeded.
