Bonjour, nous avons une boucle d'eau purifiée à un débit de distribution de 10 m3/h qui est ozonée à 15 ppb. Nous avons placé avant les points de soutirage un UV dont la dose de rayonnement est de 90 mJ/cm2. On nous préconise d'augmenter cette dose sous peine d'avoir une fuite en ozone aux points de soutirage. Savez-vous si cette dose est suffisante?. T° de l'eau distribuée: 18°C. L'analyseur d'ozone dissous en place est un Orbisphère dont la limite de détaction est 5ppb. Merci d'avance.

Bonjour, Oui votre dose d'UV est suffisante car à 90 mJ/cm2, vous aurez un abbatement d'ozone dissous d'environ 91% soit un résiduel < 5 ppb qui est le seuil limite de mesure de votre analyseur.
