  • the residual chlorine concentration was 0.6 ppm after 1 minute treatment, 0.2 ppm after 2 minutes treatment, and 0 ppm after 3 minutes treatment. That is, the residual chlorine concentration decreased as the treatment time passed, and the residual chlorine was not completely detected after 3 minutes.
  • residues residual chlorine contained in the water to be treated can be decomposed in a short time.

Abstract

L'invention concerne un appareil (1) de traitement d'eau auquel est amenée de l'eau brute (A1) à traiter et dans lequel l'eau brute (A1) est soumise à des traitements donnés dans un tuyau (92) de traitement. L'appareil (1) de traitement d'eau est équipé : d'un irradiateur (20) à ultraviolets qui est disposé sur le tuyau (92) de traitement et irradie l'eau brute (A1) par des ultraviolets ; un dispositif magnétique (40) qui est disposé dans le tuyau (92) de traitement en aval de l'irradiateur (20) à ultraviolets et applique un champ magnétique à l'eau brute (A1) en circulation ; et un composant multiplicateur (30) de radicaux qui est situé entre l'irradiateur (20) à ultraviolets et le dispositif magnétique (40) dans le tuyau (92) de traitement et multiplie au moins un radical du groupe formé d'un super-oxyde (·O2 -), d'ions hydrogène (H3O+), de radicaux hydroxyle (HO·), de peroxyde d'hydrogène (H2O2), d'oxygène singulet (1O2), d'un complexe métal/oxygène (M-OO) et d'ozone (O3).
