FIELD: chemistry, technological processes.
SUBSTANCE: water purification is performed by impact of electric discharge radiation and further action of chemically active particles and radicals, formed during electric discharge in filled with oxygen-containing gas space between sectioned metal electrode and water surface. Electric discharge is realised in filled with oxygen-containing gas space, separated from sections of sectioned metal electrode with thin dielectric layer from material, resistant to action of electric discharge and chemically active particles and radicals, formed during electric discharge. Material has electric strength more than 300 MV/m, relative dielectric permeability 5÷50, specific volume resistance 1010÷1017 Ohm·m, specific surface resistance at temperature 20°C and relative humidity 70% more than 1010 Ohm and heat conductivity coefficient more than 6 W/(m·K).
EFFECT: invention reduces energy consumption for water purification.
