Undesirable taste and odor (T&O) issues in drinking water are a major source of customer complaints for water utilities. Ozone has been used successfully to treat T&O in many existing treatment facilities. However, there is a better treatment approach with advanced oxidation process (AOP), and in particular with ozone plus peroxide and the HiPOx™ technology.

Air Products is working with municipalities to address the T&O problem more effectively with the patented HiPOx technology. The HiPOx technology is an ozone and hydrogen peroxide AOP system with a uniquely designed reactor. This technology has been shown to treat the T&O causing compounds (Geosmin and MIB) more effectively than other competing technologies such as powdered activated carbon (PAC), ozone alone or chlorine. The real benefit comes from the reactor design.

• Performs multiple treatment objectives simultaneously such as taste/odor/color and VOC removal without forming disinfection byproducts
• Destroys recalcitrant chemicals to non-detect levels
• Uniquely minimizes and controls bromate formation to help meet strict drinking water standards
• Can be operated as a highly efficient ozone contactor when T&O issues abate
• No waste streams generated Applicable to both new plants and retrofits
