UV Inactivation of Cryptosporidium
Price: £150
Ref: 08/DW/06/20
ISBN: 1 84057 474 7
Potential changes to the UK Drinking Water Quality Regulations could make Cryptosporidium inactivation using UV the most cost-effective treatment option in many situations. UV disinfection is well established in water tratment in the UK and elsewhere. There is now a substantial body of evidence to indicate that UV can provide high levels of inactivation of Cryptosporidium at doses typically used for water treatment disinfection. Turbidity below the regulatory limit of 1 NTU should not impair the disinfection performance of UV. Other water quality factors that could impair UV performance by affecting absorbance of UV or fouling of lamps can be dealt with effectively through operational control systems.
The report provides information and guidance on implementation of UV disinfaction to inactivate Cryptosporidium, based on a review of regulations and standards from other countries, particularly the USA.
