(EN) WATER TREATMENT
(FR) TRAITEMENT DE L'EAU
Abstract
(EN)
The present invention relates to a process for reduction of the presence of microorganisms and/or decomposition of organic micropollutants in water using an energy source and an additive characterised in that the energy source is UV radiation and the additive comprises performic acid.
