Oxidizable contaminants in water are destroyed rapidly and efficiently by exposing the water to oxidizing conditions under pressure. Specifically, a single dose of hydrogen peroxide may be injected into the water, followed by the repeated injection and mixing of low doses of ozone. In each such high intensity mixing/reaction stage, ozone is injected at a pressure, velocity, and direction approximately matching that of the contaminated water flow. High intensity mixing under pressure facilitates rapid and complete oxidation of the contaminants with minimal stripping of volatile contaminants and waste of undissolved ozone. Residual ozone levels after high intensity mixing may be carefully monitored and minimized by adjusting the injection of hydrogen peroxide and ozone in order to suppress the formation of bromate. Additional contaminants may be removed by passing the treated water through activated carbon beds.

L'invention concerne la destruction rapide et efficace de contaminants pouvant s'oxyder dans l'eau par exposition de l'eau à des conditions d'oxydation sous pression. Plus particulièrement, l'injection d'une dose unique de peroxyde d'hydrogène dans l'eau, peut être suivie d'une injection répétée et du mélange de faibles quantités d'ozone. Dans chaque phase de mélange/réaction à haute intensité, on injecte de l'ozone à une pression, une vitesse et dans une direction correspondant approximativement à celles du flux d'eau contaminée. Un mélange à haute intensité sous pression facilite une oxydation rapide et complète des contaminants l'extraction de contaminants volatils et la perte d'ozone non dissous étant minimales. On peut soigneusement contrôler et réduire les niveaux d'ozone résiduels après mélange à haute intensité par ajustement de l'injection de peroxyde d'hydrogène et d'ozone afin de supprimer la formation de bromate. On peut éliminer d'autres contaminants en passant l'eau traitée à travers des lits de charbon actif.
