Description
Purification and Decolorization of Alcohol & Beverages
Alcohol (such as liquor, beer, wine) is prone to produce turbidity, polyphenol oxidation pigment and sulfide odor during fermentation and storage. Activated carbon can significantly improve the clarity and taste of the wine by adsorbing colloids and taste molecules.
Generating Scenes
raw material impurities, fermentation by-products, processing pollution, storage deterioration, etc.
Adsorption Targets
colors, odor substances, organic impurities, microbial metabolites, heavy metal and pesticide residues
Application Scenes
Liquor purification, Beverage decolorization
Treatment Technology
Adsorption method: fixed bed adsorption, PAC injection
Combination process: BAC, ozone-AV combination

fermentation liquid impurities, turbidity of neutralization solution, metal ion pollution, etc.
Adsorption Targets
pigment, organic impurities, metal ions, odor substances
Application Scenes
fermentation liquid pretreatment, decolorization of neutralization solution, refining before crystallization
Treatment Technology
Adsorption method: PAC injection, GAC fixed bed
Combination process: AC – ion exchange resin combination, membrane filtration – AC combination:

Case
Activated carbon for glycerol decolorization and purification
Background: Crude glycerin produced by a biodiesel plant, containing 8% saponification and deep pigment, cannot be directly sold.
Solution: Adding wood PAC, combined with centrifugation separation of saponification.
Effect: decolorization rate 85%, glycerin purity increased to 88%, reaching the industrial standard.
Decolorization and Purification of Sugar Solution
Solution decolorization is the core step in sugar production process, which directly affects the color and market competitiveness of the product. Activated carbon adsorbs caramel pigments and colloidal impurities to ensure that the sugar solution is clear, transparent and meets the needs of high-end food processing.
