Separation by adsorption, chromatography or membranes

Christoph Buttersack

Adsorption, chromatography and membrane technology are discussed as separation processes in general and particularly in respect of their current and potential applications in the sugar industry. The porosity of the materials used for separation is regarded as the common characteristic of these processes. Ideally, separation takes place either without interaction, according to the size of the particles or molecules to be separated, or with a superimposed (specific) accumulation in the pores. The paper also looks at the undesirable formation of covering layers and the movement of substances through the walls of sugar beet cells during extraction and pressing.
