Wine and Juice Clarification Applications
Asphalt Emulsion

WINES AND JUICES. . .for clarification
Volclay bentonite, specifically, KWK Food Grade and Krystal Klear KWK are extensively used for the clarification and purification of organic liquids such as wines, fruit juices, raw sugar juices and others. It functions by adsorption and flocculation of the proteins and other undesirable impurities.

CLARIFICATION AND PURIFICATION. . . as an adsorbent
Volclay sodium bentonite suspensions combine chemically with dissolved salts present in some natural waters to form a floc that settles rapidly. The floc removes part of the salts and entraps fine suspended solids that make water cloudy. Bentonite is also used as an initiator or starter for flocs in water treatment plants using common industrial chemicals for purification. Flocs formed on Volclay bentonite hold algae better than chemical flocs. Volclay bentonite can be used to recover some industrial wastes, coal mine wash waters and blast furnace dust. Used in combination with alum, lime, salts, or polyelectrolytes, Volclay bentonite improves both the rate of settling and sludge compaction. Higher efficiency of removal results from such combinations.

Products

Volclay®

  • Volclay KWK 200
    Used in the “fining” step of processing wine, juice, cider, and vinegar for the removal of suspended solids. Particularly useful in preventing cloudiness and removing heat-sensitive proteins.
  • Volclay KWK Agglomerated
    Used for the clarification of wine, juice, cider and vinegar. Agglomerated KWK efficiently removes suspended colloidal particles. This high-purity bentonite has a high montmorillonite content, large surface area, and contains low grit. Agglomerated KWK is effective at preventing cloudiness and removing heat sensitive proteins. Agglomerated KWK is the fastest dispersing wine-grade bentonite.
  • Volclay KWK Food Grade
    Used in the “fining” step of processing wine, juice, cider, and vinegar for the removal of suspended solids. Particularly useful in preventing cloudiness and removing heat-sensitive proteins.
  • Volclay KWK Krystal Klear
    Used for the clarification of wine, juice, cider and vinegar. Krystal Klear KWK efficiently removes suspended colloidal particles. This high-purity bentonite has a high montmorillonite content, large surface area, exhibits rapid cold-water dispersion and contains low grit. Krystal Klear KWK prevents cloudiness while removing heat-sensitive proteins.
