Potable Reuse

TrojanUV advanced oxidation systems help treat wastewater to the stringent standards required for potable reuse

About 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.

The Potable Reuse Treatment Process

UV advanced oxidation and disinfection 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) destroys low-molecular-weight contaminants that can pass through RO membranes, such as 1,4-dioxane, nitrosamines (e.g., NDMA), pharmaceuticals, endocrine disruptor chemicals or industrial solvents.

Simultaneously it provides final disinfection to inactivate a broad range of bacteria, protozoa and viruses.

Microfiltration

Filters out bacteria, protozoa, and any solids in the water

Microfiltration

Reverse Osmosis

Filters out viruses, salts and chemicals

Reverse osmosis

UV + Oxidant

Destroys any remaining chemicals and provides final disinfection
