Abstract
L'invention concerne un procédé de désinfection d'une eau ayant un pH ?7,8, caractérisé par le fait que l'on règle le pH sur une valeur inférieure à 7,8 et qu'à cette valeur de pH abaissée, on ajoute du peroxyde d'hydrogène à l'eau afin d'oxyder, en l'absence de chlore libre actif, tous les micro-organismes et autres matières organiques présents dans l'eau.
