The effect of Ultraviolet (UV) on the chemical composition of water including disinfection by-products formation - WT1293

The aim of this project is to increase our understanding of the impact of ultraviolet (UV) disinfection on the chemical composition of water, with specific reference to the potential formation or removal of disinfection by-products (DBPs).
The objectives are to:

1. Review the literature on the effects of UV disinfection at specific dosages, on the chemical composition of water with specific attention to formation of disinfection by products.
2. Determine the scale and nature of UV treatment in public supplies in England and Wales
3. For a small number of works analyse water company operational data to evaluate the effect of UV dosages on chemical composition
4. Evaluate the effect of pre-oxidation on disinfection by-products formation at treatment works operating UV disinfection.
5. Summarise data held by DWI on UV usage in private supplies
6. Where appropriate consider the health significance of the findings of the objectives above.
7. Devise a sampling and analysis strategy that could be employed as part of a future research project to investigate any issues arising.
