Air Products recently announced that HiPOx technology, an ozone-based advanced oxidation process (AOP) water treatment technology, has been granted conditional acceptance by the California Department of Public Health for unrestricted water reuse under Title 22 of the California Code of Regulations. HiPOx injects and mixes ozone with hydrogen peroxide to maximize the production of hydroxyl free radicals. Hydroxyl free radicals are the most powerful oxidant available for water treatment to destroy pathogens and difficult to treat organic contaminants including 1,4-dioxane, chlorinated solvents, petroleum hydrocarbons, and endocrine disrupting chemicals (EDC).
Ozone and ozone-based AOP, like HiPOx, have been shown to provide superior results over conventional ultra violet and chlorine-based disinfection technologies. Spartan Environmental Technologies offers a variety of conventional and proprietary advanced oxidation processes. The approval of this first AOP for water use processes in California show that these technologies will have a much wider range of use than they have today. Currently such AOP are primarily used for ground water remediation and industrial water and wastewater treatment.
