Disc Filter

The Ceramec® filter is a unique rotary disc filter which uses a sintered alumina disc to dewater a slurry under low vacuum. The dewatering occurs by drawing water from the slurry by capillary action. This ensures that no air or particles are drawn into the filter medium to cause blockage. Figure 15.13 shows a cross-section of the ceramic disc.
