Hanovia is Helping Cott Beverages Keep its Process Water Pure
In an increasingly regulated and safety-conscious market, legislations such as the EU Directive for Bottled Water 98/88/EC (1998) drives the beverage industry to meet ever more stringent standards of quality. Microbial growth due to contaminated water or ingredients can cause discolouration, off flavours and shortened shelf-life. The threat of contamination is further increased as manufacturers respond to demands for less chemical additives and preservatives. Effective microbial disinfection of the whole process is therefore essential.
Since 2002, Cott Beverages has been using Hanovia’s PureLine UV disinfection technology to treat process water used in the production process. The company decided to use UV technology to ensure final product security prior to mixing and bottling.
Since the UV systems were installed the company has been very satisfied with their performance. Chris Prentice from Cott Beverages says: “Hanovia UV systems provide us with absolute insurance before bottling by making sure we are producing and maintaining a high-quality product, which is essential for our brand. The systems are easy to integrate, maintain and operate.”
There are no microorganisms known to be resistant to UV – this includes pathogenic bacteria such as Listeria, Legionella and Cryptosporidium (and its spores, which are resistant to chlorination). Unlike chemical treatment, UV does not introduce toxins or residues into process water and does not alter the chemical composition, taste, odour or pH of the fluid being disinfected.
UV is used for both primary disinfection or as a back-up for other purification methods such as carbon filtration, reverse osmosis or pasteurisation. As UV has no residual effect, the best position for a treatment system is immediately prior to the point of use. This ensures incoming microbiological contaminants are destroyed and there is a minimal chance of post-treatment contamination.
Hanovia’s UVCare training program supports businesses like Cott Beverage to make sure servicing is carried out by certified engineers.
