UV system disinfects water supply at brewery

Hanovia product story

Harveys Brewery in Lewes, East Sussex, has installed a Hanovia ultraviolet (UV) disinfection system to help safeguard its brewing process from the risk of water-borne microbial contamination.
Harveys Brewery in Lewes, East Sussex, has installed a Hanovia ultraviolet (UV) disinfection system to help safeguard its brewing process from the risk of water-borne microbial contamination.
The Hanovia system treats all water drawn from an artesian well which subsequently comes into contact with product.
UV destroys all water-borne microorganisms such as bacteria, yeasts and moulds.
It does not affect the pH or chemical composition of the water, ensuring that the unique flavour of the beer is not altered in any way.
Established in 1790, Harveys is the oldest independent brewery in Sussex.
It produces a range of draught beers, including Harveys Sussex Best Bitter, and a selection of special seasonal brews.
35, 000 barrels a year are produced, mainly for the local market, but a proportion are exported as far afield as the USA and Finland.
Speaking about the Hanovia system, the Head Brewer and Director said "Although the quality of the water from our artesian well is sound, we wanted to ensure there was no subsequent microbial contamination in-line.
We chose UV as it is the simplest system to use with the least operator risk associated with it.
By treating all water that comes into contact with product, including process liquor and rinse water, it gives us added peace of mind." Hanovia UV systems have many other applications within breweries, including the treatment of dearated, chase and make-up liquor, CIP rinse water, water for yeast propagation and pasteuriser recycling water.
They can also be used in the packaging plant for the surface disinfection of crown caps, cans and bottle necks, or for treating jetting water.
Special air treatment systems are available for disinfecting the head space in water storage tanks and for treating the air supply to yeast preparation areas.
