UV disinfection in meat and poultry processing
Control of microbial contamination is always high on the agenda in meat and poultry processing and manufacturing.
Angel Springs bottles natural spring water for use in water coolers.
"We were put off ozone by the potential for bromate formation as part of the ozonation process," said Andrew Glaister of Angel Spring.
Bromide ions occur naturally in many spring waters and are completely harmless.
If their levels are high, however, ozone can facilitate their conversion into bromate, a suspected carcinogen.
"Even though our bromide ion levels are not particularly high, we decided to go for the safer option and use UV instead," Mr Glaister added: "UV has no downsides, only upsides, and since its installation we have been happy with its performance.
The UV system has done 2000 hours so far and we won't need to change the UV lamp until after 8000 hours of operation, so it is very efficient".
The water originates from a natural spring on the site.
After filtration to remove physical particles it passes through the UV chamber and is then bottled.
There is no further water treatment and no chemical treatment.
Hanovia UV systems are compact, so installation is simple and can usually be done within existing pipework with minimal disruption to the plant.
They are very easy to operate and the only regular maintenance is changing the UV lamp every 8000 hours, a simple operation which can be carried out by on-site staff.
The Chiltern Hills plant was previously known as Chiltern Hills Watercoolers, but since its merger with Angel Springs in Wolverhampton and SPA in Halifax in 2003 a new, national company was formed and renamed Angel Springs Limited.
