Chlorine Dioxide Technology for Improved Beer Quality and Safety at Sleeman

The most abundant ingredient in beer is water, which greatly affects taste.  If inferior quality water is used, no amount of skill or technique could make a good product.  Water is also critical in the cleaning and rinsing stage of the packaging operation to ensure product quality and safety.   

chlorine-dioxide-technologyWhen Sleeman wanted to package its draught in cans, one of the important steps was to get the packaging right. Considering its draught beer is unpasteurized and free from preservatives, the entire process had to be designed carefully to provide quality and safety.   

Sleeman engaged Sealed Air (formerly known as Diversey) and decided to investigate chlorine dioxide to treat the water used in the can rinser.  Sealed Air proposed BelloZon chlorine dioxide generation technology from ProMinent Fluid Controls of Guelph, ON, which uses acid-chlorite chemistry with two Sealed Air chemicals: Divoact H-9 and CloSureCentral 7.5, and which safely produces a solution of chlorine dioxide with no free chlorine. BelloZon generators are high quality equipment that meet the stringent German DVGW guidelines for water treatment.
