Membrane Fouling and Cleaning in Food and Bioprocessing

摘要: Membrane fouling in almost all membrane processes is normally caused by precipitation and deposition of molecules or particulates on the surface pores. The consequences are increased separation resistances, reduced productivity, and/or altered selectivity. This affects factor for targeted species feed, with a consequence unstable product quality poor recovery. process includes pore blocking, solute aggregation that leads to cake formation gel layer surface, adsorption aggravated concentration polarization convective forces through membrane. There three groups major factors influence fouling, which include properties involves material from made, feed solution composition, concentration, pH, ionic condition. Pretreatments property system very important removal suspended solids conditioning reduce tendency.
