Typical examples include the following:
– Sweetener purification – cane sugar, glucose and syrups.
– Food-grade acids, e.g. citric acid, produced via a fermentation process.
– Purification of ethanol for use in alcoholic beverages.
– Removal of tannins and other impurities in the wine growing industry.
– Purification of carbon dioxide (CO2) gas produced in breweries, prior to its re-use in food-grade applications.
– A highly purified form of PAC is used as the black food colourant E153
CPL Activated Carbons offers a broad range of products, all Food Codex certified, and services for the food and beverage sector.
– Powdered activated carbons (PAC) such as Filtracarb® SK1® are offered for batch purification processes.
– For continuous, fixed-bed liquid phase purification applications, various granular activated carbons are available, including acid-washed versions such as Filtracarb® CC60 AW, which offer an even higher level of purity than standard GACs.
– For gas-phase applications, such as CO2 scrubbing, we offer a range of extruded (pellet) carbon grades, such as Filtracarb® EX64.
– For liquid-phase GAC purification processes, we can supply one of our Clean-Flo® AquaSorber® mobile carbon filters, on a rental basis.
– For gas-phase applications, various sizes of VOCSorber® mobile vessels are available.
– Spent GAC from these industries can be recycled at our ‘green’ food-grade reactivation plant in Immingham.
– Similarly, spent pellets for air/gas purification can be regenerated in our ‘amber’ industrial reactivation facility.
