UV-oxidation Process - Environmental Contaminant Treatment
UV, either alone or in combination with hydrogen peroxide, destroys contaminants in a variety of applications including drinking water, wastewater recycling, and groundwater remediation.
Increasingly, water providers are taking advantage of this dual capability of UV light to simultaneously disinfect and treat contaminants (through UV photolysis and UV-oxidation - also known as advanced oxidation) such as taste and odor-causing compounds, nitrosamines, pesticides and algal toxins.
Trojan’s installation base of municipal and industrial UV systems performing Environmental Contaminant Treatment (ECT), also known as advanced oxidation, continues to grow. A variety of water treatment facilities throughout the world employ the TrojanUVPhox™ for the treatment of various contaminants. One example is the Orange County Water District’s Groundwater Replenishment System (GWRS) in Fountain Valley, California (USA). The GWRS system provides 100 million gallons per day (MGD) of purified recycled water for augmentation of local drinking water supplies in highly water-stressed southern California. The TrojanUVPhox™ disinfects and destroys trace contaminants that pass through the reverse osmosis membrane treatment system.
Another example of a Trojan municipal ECT installation is the PWN Water Supply Company’s Andijk Drinking Water Facility in the Netherlands. The TrojanUVSwift™ECT has acted as a barrier to pesticides while disinfecting at this 25 MGD facility since 2004. As drinking water regulations for pesticides in Europe are particularly stringent, the TrojanUVSwiftECT™ is responsible for removing any pesticides that may be present in the lake water to below 0.1 microgram per liter.
Each installation is backed by extensive performance guarantees, and Trojan provides application expertise and optimization as treatment goals and site conditions change over time. Trojan also provides full-service supply of hydrogen peroxide to support UV-oxidation installations.

What are Environmental Contaminants?There is a growing awareness of chemicals in the world's water supply. Recent research has shown that a wide variety of such chemicals exist at trace concentrations in streams, lakes, rivers and groundwater throughout the world.
Advanced Oxidation - Indirect Potable ReuseThe reuse of wastewater for augmentation of drinking water supplies (a process known as indirect potable reuse or IPR) is rapidly gaining support as a means of achieving a sustainable water supply and for protection against drought.
Seasonal Taste & Odor TreatmentWhen algae blooms die in late summer/early fall, chemicals such as geosmin and 2-methylisoborneol (MIB) are released causing water to smell and taste earthy or musty.
Advanced Oxidation - Contaminant TreatmentWater sources, groundwater and surface water, are increasingly impacted by contamination. With population pressures, climate change, and overuse making every water source important, water providers are increasingly looking to advanced treatment...
Advanced Oxidation - Groundwater RemediationIn many areas, localized releases of industrial chemicals, pesticides, petroleum additives such as MTBE, and fuel components such as benzene and hydrazine, have impaired groundwater quality. These groundwater “plumes” are commonplace...
