In many chemical and pharmaceutical processes, solid-liquid separation, cake washing and drying steps directly impact the effectiveness of the production operation. In solid-liquid separation, there is a choice both of the type of filter media and the thickness of the cake or the cake depth during which the separation occurs. This article by Barry A. Perlmutter, President of BHS-Filtration, discusses the choice of thin-cake (2 – 25 mm) separation technologies and outlines best practices for implementing clean-in-place operations and associated control systems.
