Ultraviolet disinfection
The Illustrated Guide to Hot and Cold Water Services (BG 33/2014), written by Reginald Brown and published by BSRIA in 2014. In relation to ultraviolet disinfection, it states: ‘Hot or cold water is passed through a high intensity ultraviolet cell. There are no chemical risks with this method, and it is widely used as a precautionary measure to reduce the levels of general bacteria in incoming water supplies (mains or borehole) and for point of use disinfection for critical applications. Ultraviolet disinfection is effective against all bacteria at the point of exposure but not persistent. Some manufacturers claim a downstream beneficial effect on microbiological water quality.’
