Free from contamination
July 1st 2006

Hanovia ultraviolet (UV) water disinfection systems are helping the Silver Spring Mineral Water Company in Folkestone ensure its products are free from microbial contamination.

"We have a very pure source of spring water," said Steve Clegg of the engineering team, "but we feel a 'take no chances' approach to water purity is best, and UV provides us with that extra reassurance".

UV is highly effective at destroying all water-borne microorganisms, including bacteria, yeasts, moulds and their spores. It does not affect the pH or chemical composition of the product, ensuring the flavour is not affected. Each UV system consists of a stainless steel treatment chamber containing one or more UVemitting tubes. Water passes through the chamber and the UV kills any microorganisms present by destroying their DNA.

Seven Hanovia UV units are now installed at Silver Spring, the oldest of which has been in use for over ten years.
