In order to improve the performance of the centrifuge, a new design of dewatering of slurry which forms a less permeable cake is proposed. In the proposed design, the filter media is placed not only on the circuit, but also at the bottom of the filter chamber. The additional bottom filter medium is expected to work as a bypass. A comparison of the conventional and new designs is made in this study. The supernatant is completely discharged in a much shorter time when the new method is used; hence, the filter medium at the bottom of the filter chamber works as a bypass and improved the dewatering performance.
