FUTURE POOL WATER TREATMENT IN PUBLIC SWIMMING POOLS
Research objectives
The research objective is to reduce the use of chemical disinfectants in public swimming pools. This can be
done by combining alternative disinfection techniques with adapted water treatment in a new pool water treatment
concept including aspects of hygienic control of pool visitors. The goal is to have chemical disinfectant
free swimming pool water during the public opening hours.
Project outline
Introduction
The main disadvantage of the use of a chemical disinfectant in pool water treatment is the formation of disinfection
by-products. Operating pool water treatment without a chemical disinfectant introduces new questions
like:
- Can human pathogens be controlled in swimming pool water, using alternative disinfection techniques?
- What effects will alternative disinfection techniques have on the design of the pool water treatment?
- What is the effect on other water quality parameters like turbidity, urea and organic matter?

and experimental basis. During the lab scale tests, chemical and biological pollutants will be dosed to determine
which alternative disinfection technique is within reach for swimming pool operation. The most promising
technique will be tested full scale in a swimming pools During these full scale tests the robustness of the
alternative technique will be an important parameter.
