Ozone-based technology meets disinfection criteria for unrestricted water reuse

Applied Process Technology Inc. has announced the acceptance of its HiPOx process by the California Department of Public Health as the first ozone-based technology accepted to meet disinfection criteria for unrestricted water reuse under Title 22 of the California Code of Regulations. The acceptance granted by the State of California is manufacturer- and product-specific to the HiPOx process for ozone disinfection.

• HiPOx® process accepted to meet disinfection criteria for unrestricted water reuse under Title 22 of the California Code of Regulations

PLEASANT HILL, CA, Oct. 29, 2008 -- Applied Process Technology Inc. announced the acceptance of its HiPOx® process by the California Department of Public Health as the first ozone-based technology accepted to meet disinfection criteria for unrestricted water reuse under Title 22 of the California Code of Regulations. The acceptance granted by the State of California is manufacturer- and product-specific to the HiPOx process for ozone disinfection.

The HiPOx process for municipal applications is marketed to water agencies nationwide by Applied's exclusive licensee Air Products and Chemicals Inc. The HiPOx process is a pre-packaged treatment system with a unique plug flow reactor that efficiently injects and mixes ozone or ozone and hydrogen peroxide to maximize the production of hydroxyl free radicals (the most powerful oxidant available for water treatment) to destroy pathogens and recalcitrant compounds such as 1,4-Dioxane, chlorinated solvents, petroleum hydrocarbons, and endocrine disrupting chemicals (EDCs). HiPOx has the flexibility to operate in either the ozone-only mode or the AOP mode. In the AOP mode, HiPOx has the capability to provide patented bromate control.

"We are proud to bring this significant new treatment option to the water utility industry," stated Terry Applebury, President of Applied Process Technology Inc. "The reuse of scarce water resources is a significant issue in many regions of the U.S.A. Our company's California location enables Applied to be at the forefront in providing advanced and waste-free solutions for the environment. Since HiPOx is the only ozone-based technology to be accepted under California's Title 22 requirements, this approval provides Applied's partner, Air Products & Chemicals Inc., with a new tool for utilities and engineering firms seeking to address the region's water reuse priorities."

HiPOx provides a superior platform for meeting both water reuse disinfection guidelines and destroying EDCs and other trace organics to protect public health. Many studies have been conducted regarding the treatment of EDCs and other trace organics in drinking water and wastewater. Ozone and ozone-based AOP have been shown to provide superior results over conventional UV or chlorine-based disinfection technologies. While many EDCs and other trace organics are not yet regulated, these emerging compounds will guide design and technology selection in the future.

Applied Process Technology Inc. consists of a team of engineers and scientists focused on advanced oxidation and advanced reduction processes for water treatment.
