Abstract: Decontamination of water polluted with organic and microbial pollutants, and biomedical effects on cells mediated through aqueous solutions can be efficiently achieved by using various non-thermal plasma discharges. These effects can be further enhanced when air discharges are combined with water electrospray. The presence of the electrical discharge generating non-thermal plasma in the spraying area allows for very efficient mass transfer of plasma-generated species into the water [1, 2].
We investigated the effect of the electrospraying of water in combination with positive DC corona discharge. Our key finding is that the discharge has a significant effect on the electrospray behavior and vice versa [3-6]. Such water electrospray-air discharge system was demonstrated to be very efficient in inducing bactericidal and various chemical effects in treated water [1, 7].
