Abstract

Advanced oxidation technologies (AOT), such as non-thermal plasmas, are considered to be very promising for the purpose of water treatment. The goal of this study is to test the feasibility of "Corona-above-water" technology for the treatment of drinking water. Experiments have been performed on the removal of the substances phenol, MTBE, NDMA and Geosmin from tap water. The presence of these substances in drinking water is expected to become problematic in the coming decade, and novel technologies need to be developed to control their concentrations and the products formed from treatment. It is concluded that the Corona-Above-Water technology can be used to (partially) convert pollutants as MTBE, NDMA, Geosmin and phenol in water. Full mineralization of harmful target compounds is unnecessary and energetically inefficient. AOP’s should be regarded as pre-treatment tool to (microbiological) degradation methods for polluted water flows, by reduction of initial harmful toxity.
