The Laboratory of Environmental Technology at Tallinn University of Technology (TalTech) specializes in research on the application of advanced oxidation processes (AOPs) in drinking water, water reuse, and wastewater treatment. A cutting-edge direction in AOP research is the application of gas-phase pulsed corona discharge (PCD) plasma, which demonstrates exceptional energy efficiency in the oxidation of organic pollutants, surpassing the closest commercially available competitor, ozonation, by a factor of two to ten.
The Laboratory works in close cooperation with a company that develops and manufactures PCD devices, which have been tested in a wide range of applications, from drinking water treatment to heavily polluted waste streams such as coal coking liquors, paper industry recycling effluents, hospital wastewaters, and even source-separated human urine. The results of these studies have been published in scientific journals.
The devices have demonstrated high reliability, showing no malfunctions when treating media with conductivities of up to 120 mS/cm in an oxygen atmosphere. Owing to the specific features of oxidation in heterogeneous gas-liquid systems, in which the liquid is sprinkled into the plasma, targeted oxidation of micropollutants is achieved. As a result, the energy efficiency can be up to an order of magnitude higher than that of conventional ozonation and other AOPs.
