What two processes combine in the Advance Oxidation Process in California?

The Advanced Oxidation Process (AOP) is a water treatment method that effectively reduces contaminants through the generation of hydroxyl radicals. These radicals are highly reactive and play a crucial role in breaking down complex organic molecules. The specific combination of ultraviolet (UV) light and hydrogen peroxide (H2O2) is a primary method used in AOP.

When UV light is introduced into water containing hydrogen peroxide, it initiates a photolytic reaction that decomposes hydrogen peroxide into hydroxyl radicals. This generates a powerful oxidizing environment capable of degrading organic pollutants, pharmaceuticals, and other contaminants that are otherwise resistant to conventional treatment methods.

This combination is particularly effective in California, where advanced treatment processes are increasingly utilized to ensure the safety and quality of recycled water for various uses, including indirect potable reuse. The synergy between UV and hydrogen peroxide provides a cost-effective and efficient means to enhance water treatment systems in the pursuit of recycled water standards.
