The aim of the work was the investigation of biodecontamination of water contaminated by Salmonella typhimurium, by using two types of direct current (DC) electrical discharges in atmospheric air, in point-to-plane geometry of electrodes. We used streamer corona and transient spark in both polarities (positive and negative). We also investigated the effect of these discharges on decolorization of water contaminated by organic dyes. It is well known that DC atmospheric discharges generate non-equillibrium plasma with a high electron densitiy and with a relatively low gas temperature (to 650 K). This  is important for various environmental applications. These kind of discharges generate high concentrations of various active species and radicals. In our case, the water was flowing directly through the HV needle electrode into the active discharge area. In this configuration we observed the effect of electrospraying of water. In all cases, we observed a significant decrease of bacteria concentration (efficiency 90 %). Also the the decrease of organic dye color intensity was observed. The radicals and active species play a major role in the process of decontamination.
