TrojanUV advanced oxidation systems help treat wastewater to the stringent standards required for potable reuse
Potable reuse is the process of recycling wastewater for the augmentation of drinking water supplies
Indirect potable reuse (IPR) treats water for the replenishment of groundwater supplies, indirectly back to drinking water
Direct potable reuse (DPR) treats water for direct injection into drinking water reservoirs or drinking water supply networks
To meet the increasing demands for clean drinking water, many municipalities are looking at solutions beyond what was previously accessible or considered conventional. Many are turning to water reuse as a sustainable means of securing a local, drought-proof, and safe water supply.
UV advanced oxidation and inactivation of microorganisms are key elements in the potable reuse treatment scheme and ensures the highest quality water is produced – water that exceeds the standards for drinking water supplies.
When treating wastewater for potable reuse, advanced processes including microfiltration, reverse osmosis (RO) and UV advanced oxidation have set the standard. When used in combination, they ensure the highest quality water is produced.
The advanced oxidation process (UV AOP) breaks down low-molecular-weight contaminants that can pass through RO membranes, such as 1,4-dioxane, nitrosamines (e.g., NDMA), pharmaceuticals, endocrine disruptor chemicals, and industrial solvents.
Simultaneously, it provides final treatment to inactivate a broad range of microorganisms.
Filters out larger microbes and any solids in the water
Filters out smaller microbes, salts, and chemicals
Breaks down any remaining chemicals and provides inactivation of any remaining microorganisms
The Groundwater Replenishment System in Orange County, California, is the largest indirect potable reuse project of its kind in the world. It utilizes treatment technologies including the TrojanUVPhox® for advanced oxidation.
The TrojanUVPhox at the Raw Water Production Facility in Big Spring, Texas, helps treat secondary wastewater to a standard that allows it to be re-introduced directly into the raw water supply for local drinking water treatment plants.
The TrojanUVFlex®AOP is our latest UV advanced oxidation solution for the treatment of contaminants. Its cross-flow lamp orientation enhances treatment efficiency and provides built-in redundancy. A compact and modular chamber design allows for easy expandability and installation in even the smallest of spaces.
