Abstract
In this paper there is described filtering process for separating reaction mixture after enzymatic hydrolysis to process the chromium tanning waste. Filtration of this mixture is very complicated because it is case of mixture filtration with compressible cake. Successful process strongly depends on mathematical describing of filtration, calculating optimal values of pressure difference, specific resistant of filtration cake and temperature maintenance which is connected with viscosity change. The mathematic model of filtration with compressible cake we verified in laboratory conditions on special filtration device developed on our department.
Highlights
Filtration belongs to the most common cases practically making use of phenomena taking place during the flow of liquid through a layer of granular material

The objective is to separate solid particles from the liquid in which they are dispersed. This separation is achieved during filtration by forcing the liquid containing solid particles through a porous barrier
Summary
Filtration belongs to the most common cases practically making use of phenomena taking place during the flow of liquid through a layer of granular material. Its industrial application is similar to laboratory filtration performed on filter paper in a filter funnel. The objective is to separate solid particles from the liquid in which they are dispersed. This separation is achieved during filtration by forcing the liquid containing solid particles through a porous barrier. Solid particles get caught in pores of the barrier and gradually build up a layer on it. Liquid passes through the particle layer and porous barrier and leaves, gradually freed of its solid phase
