Comparison between cross-flow micro-filtration with inorganic membranes and diatomite filtration

Cross-flow filtration is a technique using the porous structure of inorganic or organic film to clarify liquor by liquor washing and differential pressure between outside and inside of film pipe.Diatomite filtration is a technique using the natural porous structure of diatomite to filter original solution by differential pressure between two sides of filter.With theoretic and experimental analysis,the principle,characteristics and application effects of cross-flow filtration and diatomite filtration were compared,which would supply theoretical instruction for condiment industry to choose filtration equipments.
