A set of air-water discharge induced by double DBD device has been designed to obtain hydrogen peroxide (H2O2) and ozone (O3) levels, simultaneously. How the H2O2 and O3 are being produced, which have extensively been studied by different experimental approaches such as air cooling, atomization amount, voltage applied, pH value and electrical conductivity (EC). | The chemical properties of air-water discharge induced by double die-lectric barrier discharge
