Abstract

La présente invention concerne un système portatif de désinfection à l'ozone pour la désinfection d'agents pathogènes de matières dangereuses rencontrées par du personnel d'urgence. Le système comporte un système de génération d'ozone couplé à un système venturi servant au mélange d'ozone avec de l'eau. Un système de filtration d'air et de séchage capable d'émettre de l'air avec un point de rosée inférieur à 60°F est couplé au générateur d'ozone permettant la production de 5 à 6 gph d'ozone. La sortie de potentiel d'oxydo-réduction du système portatif est de préférence comprise entre 840 et 910 mV, ou 0,7 à 1,3 ppm. Un contacteur débimétrique positionné en ligne après le système venturi et couplé au système de génération d'ozone ne permet la production d'ozone qu'après le début de l'écoulement d'eau ou lorsqu'il a atteint un débit prédéterminé à travers le système venturi. Le système comporte également un système de débit comportant une buse de clapet à bille d'orifice à passage intégral pour distribuer de l'eau ozonée.
