Advanced Oxidation

Trussell Technologies has the expertise to evaluate innovative oxidation technologies for water and advanced wastewater treatment, including UV/Photolysis and Advanced Oxidation Processes, such as UV/Hydrogen Peroxide, Ozone, and Ozone/Hydrogen Peroxide.  UV/Photolysis and advanced oxidation processes (AOPs) are complex technologies affected by many factors. Trussell Technologies has the expertise to provide guidance to utilities in their application.  In drinking water, advanced wastewater, and water reuse applications, there are emerging contaminants challenging the industry. Emerging contaminants include persistent organic pollutants (POPs), endocrine disruptors, and pharmaceutically active agents, some of which are recalcitrant and cannot be reduced by traditional processes. For such recalcitrant compounds, UV photolysis and AOPs represent a promising technology for target compound reduction.  To evaluate the reduction of emerging contaminants in an AOP, it is necessary to determine the hydroxyl radical rate constants for each emerging contaminant. For processes involving UV light, it is necessary to determine quantum yield and extinction coefficients to evaluate reduction by direct photolysis.  Trussell Tech can provide guidance and design experiments for determining rate constants, quantum yields, and extinction coefficients for emerging contaminants including POPs, endocrine disruptors, and pharmaceutically active agents.
