• Active carbon decolorization filtration of sugar solutions such as granulated sugar and glucose, clarification filtration of alcoholic beverages, juices, beverages, etc.; filtration of high fructose corn syrup; decarbonization and decolorization filtration of citric acid, malic acid, sulfamic acid, and lactic acid; filtration of lycopene; decarbonization and decolorization filtration of monosodium glutamate; precision filtration of yeast and soy protein; precision filtration of various juices; filtration of soy sauce and vinegar; precision filtration of alcoholic beverages and beverages; precision filtration of crude oil, edible oil, and blended oil.

• In the petrochemical industry, inorganic chemical industry, fine chemical industry, and organic chemical industry, separation of crystals in various filtrations, filtration and separation of various catalysts, decolorization filtration of chemical products, removal of impurities from electrolytes, removal of metal scraps and slag, removal of slag from phosphating, concentration and thickening of chemical products, etc.

• Clarification filtration of various pharmaceuticals using sand filters to filter out suspended solids. The filtration speed is high. It belongs to coarse filtration, and the turbidity of the influent water affects the filtration effect.

1. Completely enclosed filtration without leakage and any environmental pollution.
2. The filter cake can be washed and dried, enabling one-time complete filtration to obtain the greatest economic benefits.
3. Gas back-blowing is used for slag discharge, which is clean and rapid. It is suitable for a variety of viscous materials, has a wide application field and good filtration effect.
4. The filter element design adopts a compound structure (internal metal mesh support + external filter cloth). The entire filtration process can be fully automated (according to the automated configuration of pipelines).
