Thin-cake filtration for high-resistant slurry by use of dynamic filter with rotating cylinder

Clean-in-place Operations for Thin-cake Filtration Technologies

INTRODUCTION In many chemical and pharmaceutical processes, solid-liquid separation, cake washing and drying steps directly impact the effectiveness of the production operation. Process engineers devote much of their time to analyzing these steps. The solid-liquid separation step can be by pressure, vacuum or centrifugation as well as in a batch or continuous mode. In this separation step, ther...
