The Role of the First Solid Layer Compression in Solid-Liquid Separation: Application to Filtration, Expression, Sedimentation, Filtration by Centrifugal Force and Tangential Filtration.

초록

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 sedimentation theories are developed by above new conception using Darcy's equation. The role of the solid compressive pressure on a cake surface for centrifugal filtration and tangential filtration is also discussed.
