Combination of thickener and continual pressure filter to improve solid/liquid separation processes. The fundamental concept of the proposed process combination, which basically entails a division of the whole solid/liquid separation stage into sub‐stages, is presented. The influence of the suspension's concentration on the formation and dewatering of filter cakes under ideal conditions is then discussed, after which possible deviations of the product from the ideal behaviour are described along with their influence on the process results. Actual engineering conditions are then considered, and the consequences of a suspension pre‐thickening for the results of a drum filter are demonstrated. The conditions necessary for satisfactory results are discussed. Based on the results of conventional filtration, the further increase in filter efficiency occurring on avoiding the conventionally unavoidable gas throughput by a new process is explained. Finally a conceivable combination of apparatus for performing the described process is sketched.
