3 Reasons Why Municipalities
Choose UV AOP

  1. Effective Contaminant Removal
    Not all contaminants can be removed from water using standard treatment processes like filtration or air stripping. For contaminants such as 1,4-dioxane and certain nitrosamines, UV AOP is the only practical and proven solution.

  2. Compact Footprint
    UV AOP occurs instantaneously within the UV chamber, eliminating the need for the large concrete contact basins or steel pipes commonly used in conjunction with ozone. UV advanced oxidation systems can also be easily retrofitted into existing water treatment facilities.

  3. Remediation + Disinfection
    UV disinfection can also be used to obtain log reduction credits for bacteria, protozoa and viruses. This is ideal for water providers needing to meet requirements of the Surface Water Treatment Rule, Long Term 2 (LT2) Enhanced Surface Water Treatment Rule, or the Groundwater Rule, in addition to their contaminant removal needs

Reuse & Remediation in Action

The Tucson International Airport Area Superfund Site is located in the Tucson Basin in Pima County, Arizona. As early as 1942, metals, chemicals and other wastes were disposed of in the region, which unfortunately led to aquifer contamination.

The Tucson Airport Remediation Project was established and a groundwater treatment system was commissioned, however, continued monitoring of the groundwater detected 1,4-dioxane, a contaminant not easily removed through the air-stripping treatment system used at the original treatment plant.

Pilot studies were conducted to evaluate UV-oxidation as a possible solution. Evaluation was based on three independent criteria: treatment capabilities, by-product formation and residual hydrogen peroxide quenching.

The Groundwater Replenishment System, located in Orange County, California, USA, provides purified recycled water for aquifer recharge to replenish supplies and to prevent seawater intrusion. A joint project between the Orange County Water District and the Orange County Sanitation District (OCSD), it is the largest indirect potable reuse project of its kind in the world. The GWRS treats and reuses wastewater that, in the past, had been discharged to the ocean. The water is reused to provide protection against drought and as a means of achieving a sustainable water supply.

The full-scale Advanced Water Purification Facility takes filtered secondary effluent from the neighboring OCSD wastewater treatment plant and converts it to water that exceeds all drinking water quality standards. The microfiltration, reverse osmosis, and the TrojanUVPhox system treats up to 100 million gallons per day.
