Abstract: | Based upon a new conception that the solid compressive pressure on a cake surface is not null, almost of all solid-liquid
separation operations have been re-examined. For cake filtration, the phenomenon caused by the solid compressive pressure
on a cake surface is discussed for thin cake. New expression and hindered sed-imentation theories are developed by above new
conception using Darcy’s equation. Application of the new conception to centrifugal filtration and tangential filtration is
also discussed. Above results lead to the conclusion that cake filtration, expression, hindered sedimentation, centrifugal
filtration and tangential filtration can be described with a unified theory, and the main difference between the operations
is only the boundary condition of cake. |
