When the microporous plates are submerged into the pulp, filtering elements remove the liquid in contact with their surface due to the capillary effect. The vacuum pump applies the driving force to move the slurry liquor through the ceramic elements and into filtrate pipes. On the outer surface of the elements the filter cake forms rapidly, the effective design of the sectors prevents the passage of fine solids and air through the filtrate system.

As the ceramic filter elements rotate above the slurry level, the capillary action within the ceramic elements continuously removes the residual moisture from the filter cake. This highly efficient dewatering process produces low final cake moistures at minimum operation and maintenance costs, compared to the trade-Dtional dewatering systems

The ceramic scraper knives cleanly and effectively shave through the formed and dewatered filter cake. A layer of solids remain on the filter element providing protection from the mechanical abrasive action, This design results in reduction of the maintenance costs and increase of the service life of the ceramic filters.

At this stage, clean plant water is applied to the back wash the internals of the ceramic filter elements and to remove the residual filter cake. This process effectively cleans both the ceramic sectors to maintain maximum filtration rates and the lowest final cake moisture. The pressure and flow of the wash water during this regeneration operation automatic control under.
