In the bottling and brewing industry the process water and carbonating gases may require additional purifying treatment.
Tannin Treatment:
The treatment of tannic acid for flavour and odour removal is a process application in brewing where carbon adsorption is used. Since the tannic acid is treated at a low pH, Chemviron recommends an acid washed carbon, notably CPG®LF, for this application
Decolourisation of "Clear" Beers:
Carbon is also used to remove colour from malts for use in clear beers and other flavoured malt beverages. Several granular and powdered products can be used for this type of application. Generally, granular carbons such as CAL® are more efficient than powdered carbons, and avoid disposal issues. Where powdered products are needed for batch processing, however, Chemviron has several types available.
SUMMARY OF OTHER BEVERAGE APPLICATIONS
| Beverage | Activated Carbon Application |
|---|---|
| Vodka | Colour, Taste and Odour |
| Fruit juice | Decolourisation and patulin (mycotoxin) removal in apple juice |
| Beer | Taste and Odour Correction |
| Brandy, Whisky | Ageing stability |
| Rum, Sake, Vermouth | Colour/Taste |
| Wine | Colour, Hue and Taste. Mycotoxin removal (ochratoxin A, OTA) |
Even when the incoming process water is from a municipal drinking water source, the water may contain trace organics and residual tastes, odors, disinfection by-products, and free- and combined-chlorine that requires final treatment/removal. Depending on the quality of the incoming water, there are a variety of activated carbon products and solutions that improve water quality for the brewing/bottling industry.
Activated Carbon and Ion Exchange systems can also used to remove color from malts for use in clear beers and other flavored malt beverages.
Products that require carbonation typically utilize activated carbon treatment of gases to remove unwanted taste and odors.
Granular activated carbon
Activated carbons are an effective treatment to help ensure that water and gases are contaminant-, taste- and odor-free.
Reactivation services
Chemviron can offer safe and economical spent carbon handling and thermal reactivation in conjunction with fresh carbon supply and provide personnel and equipment to perform the carbon exchange on a turn-key basis.
Equipment
Chemviron can bundle the performance advantages of activated carbon with equipment (service or purchase) and related services, to provide full turnkey solutions. Many times the equipment will be customized to fit the requirements of the application and customer site requirements.
