Mastering The Application Of UV Advanced Oxidation Using Chlorine In California (Article)

Mastering The Application of UV.jpg

Installed at the Albert Robles Center (ARC) in California is the TrojanUVPhox™. Arranged in two parallel trains, the UV AOP system was designed to operate with sodium hypochlorite being injected into the treatment stream instead of more traditional hydrogen peroxide (H2O2). This is commonly referred to as a UV/chlorine or UV/Cl2 approach to UV AOP.

This critical difference in applied oxidants can allow for more efficient generation of the powerful radicals that break down chemical contaminants during the UV AOP process.

ARC officially began producing advanced treated recycled water for groundwater recharge in Summer 2019 and has been permitted by the California State Water Resources Control Board to deliver advanced treated recycled water to the spreading grounds. As part of the permit, the TrojanUVPhox provides removal of both 1,4-dioxane and N-nitrosodimethylamine (NDMA). In addition, the UV system is credited with disinfecting 6-logs (99.9999%) of enteric viruses as part of the broader pathogen treatment requirements for potable reuse systems.
