Description

Recently plasma activated water (PAW) has drawn huge attention because of its potential applications, such as disinfectant and natural fertilizer. In this paper, we report on the efficient fabrication methods of PAW by a non-thermal plasma. As a non-thermal plasma source, we used the dielectric barrier discharge (DBD). The properties of the produced PAW were analyzed in terms of pH, conductivity and NO3 ion concentration.
In order to improve production efficiency (= production volume of PAW/kWh) and uniformity of discharge plasma, the optimum configuration of electrodes in the DBD was investigated. PAW production rate of 120 L/h and production efficiency of 40 L/kWh has been achieved through the optimized configuration of electrodes in the cylindrical DBD geometry.
