Abstract

Methods of improving the efficiency of solid-liquid separation during centrifugal filtration have been developed. They consist of increasing the pressure drop across the filter cake using extraneous means such as increasing the gas pressure inside a filter chamber and/or applying vacuum on the outside. The extraneous means of increasing the pressure drop is designed to increase the rate of removing liquid (water) during the drainage period of the centrifugal filtration process and, hence, lower the amount of the residual liquid (water) left in the filter cake.
