    Carbon Dioxide (CO₂) is a by-product of many different processes. Each source type can have source-specific impurities.

    These should be removed by the industrial gas supplier during the purification process, but small traces can remain. Carbon Dioxide vapour is the only industrial gas used as an ingredient by the beverage industry. It has many uses, but the most important one is for carbonating the beverage. Without CO₂, our beverages would not sparkle.

    Beverage brand owners and manufacturers protect their products and processes by requiring multi-stage CO₂ vapour polishing filtration systems.

    Without this protection the finished beverage is at risk of being contaminated. This contamination can result in off-flavours, smells and appearance.

    The beverage industry and its CO₂ suppliers set quality guidelines which are strictly followed to ensure the beverage is 100% safe.

    Carbon Dioxide Purification

    Improving Beverage Security and Quality via Protection of Carbonation CO.

    Consistent high-quality CO₂ in carbonisation of beverages is important for product security of carbonated beverages.

    Acting as vapour polishers, carbon dioxide purifiers are designed to purify gas to the beverage quality guidelines. The systems provide in-line quality protection against peak levels of trace contaminants that may occasionally be present in beverage grade carbon dioxide.

    The unit’s capacity may be matched to the required process flowrate by adding or removing adsorption cartridges and columns. The protection unit is installed after the vaporiser and processes the CO₂ in its gaseous phase.

Wine clarification

Insoluble matter suspended in the wine is removed before bottling. Clarification may include fining, filtration, centrifugation, flotation, refrigeration, pasteurization and/or barrel maturation and racking.

Wine filtration

Passing wine through a filter medium that captures particles larger than the medium’s openings.

  • Coarser depth filtration
  • Fine filtration
  • Surface filtration
  • Cross-flow filtration
  • Micro-filtration
Wine filtration

Membrane pre-filtration

  • Food & Beverage filttration that help to protect and extend the service life of microporous membrane final filters.
  • Final membrane filters benefit from having a pre-filter installed upstream in the process.
  • Pre-filters help protect the more expensive final filter, extending their service life and resulting in an overall reduction in the cost per volume filtered.

Water filtration

Whether for bottle washing, system flushing and sanitation or cooler blending, clean, particle free water is required to protect the integrity of the process system and optimise wine filter life.

  • Regeneration and sanitation water
    Filtering sanitising water prior to using it in the system is essential so that the system is not contaminated with particulate in the sanitising water between wine production runs.
  • Washing and blending water
    Particulate and biological control is required for water that is used for cooler blending or in bottle washing operations. The reduction of spoilage organisms from water protects the final product from infection and spoilage.
  • Chlorine reduction filters
  • Microbial reduction Filters
  • Particle control filters

Final membrane filtration

  • Microporous membrane filters that help control microorganisms in finished wine.
  • Removes microorganisms that may lead to re-fermentation or production of “off”- flavours in the bottle.

Diatomaceous Earth (DE) trap filtration

  • DE filters can release small amounts of unwanted DE fines into the wine during processing.
  • Many wineries install the DE trap filter to catch any stray DE fines before they continue with the process.
  • Air and gas filtration
  • Filters that help control particulate and microorganisms in water used in the winery.
  • Water filtration: Particulate and turbidity control.
  • Filters that help to control particulate and microorganisms in water used in soft drink production.
  • This treatment can involve carbon filters, sand filters, neutralisers, and particle control filter cartridges.
  • Concentrate filtration.

Filter that helps reduce hazes in soft drink concentrates.

  • Sweetener filtration

Filtration that help reduce particulate and improve colour in sweeteners.

  • Final filters: particulate

Filters that help control particulate prior to bottling.

  • Final filters: microorganisms
Soft Drink Filtration
  • Air and gas filtration

    • Air or other gases coming in contact with bottled water should be sterile filtered to help prevent secondary contamination.
    • Particle filtration
    • Sterile filtration

    Taste and odour reduction

    • Activated carbon filters help reduce objectionable taste and odour in bottled water.

    Rapid hygiene monitoring

    • This offers rapid and reliable solutions to monitor biological contamination on surfaces and in water.
    • Effective environmental hygiene management helps reduce levels of contamination in finished products, leading to improved quality, fewer batch rejections and lower risk of product recall.

Controlling particulate in edible oil processing

  • Filter bags, and filter bag replacement systems to help control particulate during processing and at final load-out.
  • Certain process steps in the production of edible oils, such as bleaching, hydrogenation, and deodorization, can create unwanted particulate.
  • If not removed from the oil, this particulate matter can diminish the quality of the oil. 3M Purification developed the DF series of filters to retrofit conventional filter bag housings.
  • The unique design of the DF-series filter provides 62% more surface area compared to a conventional filter bag. This leads to increased service life, and fewer filter change-outs.
