In the water treatment industry, swimming pools are in their own niche. With no legal framework to adhere to, PWTAG are the only body who's recommended levels guidelines hold much authority, and then only in the commercial sector.

When comparing ultra violet disinfection with Chlorine dosing you'll find that it's more of a case of using both, not either/or. When using UV treatment in swimming pools, combined Choline levels are kept low. They'll actually go down to 0% with good bather hygiene and constant UV treatment. The issue that we often face is that installers are unaware of the benefits of using UV alongside Chlorine dosing in swimming pools.
