Growing populations and urban density are putting pressure on available water supply, leading communities to have to use more contaminated water sources. In addition, there has been a rise in detectable levels of undesirable microconstituents in water. These factors are driving communities toward advanced methods of water treatment.
Consequently, ozone use in drinking water and water reclamation has increased significantly over the past several years. While ozone has been used successfully for disinfection and taste and odor control in many existing treatment facilities, this “conventional ozone” application can be greatly enhanced by Air Products’ Halia™ advanced oxidation system, especially when it comes to treating highly contaminated water.
The Halia advanced oxidation system, which incorporates the HiPOx® technology (HiPOx is a registered trademark of APTwater, Inc.), is a flexible reactor that can be used as either an advanced oxidation process (AOP) reactor or a highly efficient ozone dissolution system. In AOP mode, the reactor combines ozone and hydrogen peroxide (H2O2) to maximize the production of hydroxyl free radicals. Hydroxyl free radicals are one of the most powerful oxidants 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 (EDCs). In situations where increased oxidation performance or AOP is not needed, the hydrogen peroxide can simply be turned off. This operational flexibility allows the user to optimize performance while minimizing operating costs.
