HOW CakeFil WORKS

Unfiltered medium enters the filter via the feed nozzle [1] and is distributed via the feed chamber [2]. It passes through the filter cloth and the filter candles [7] from the outside to the inside and leaves the candles again via the head plate [3] into the filtrate chamber [4] before leaving the filter completely via the filtrate nozzle [8]. The solids form a permeable “filter cake” on the cloth.

The filtrate chamber is drained through the filtrate nozzle [8] and the upper part of the feed chamber is drained through the feed drain nozzle [5] to its level. The complete filter is pressurized with air or nitrogen. A sudden release of pressure through the pressure relief nozzle [6] forces a rapid reverse flow of filtrate through the filter cloth from inside to outside. This results in an effective removal of the filter cake, which is resuspended in the fluid inside the feed chamber. It also removes solids from inside the pores of the filter cloth. The homogenous slurry is discharged through the bottom drain nozzle [9].
