Apparatus for decontamination and disinfection of aqueous solutions consists of two separated chambers that are filled and circulated with aqueous solution. Electrodes, one grounded and second connected to the high voltage DC source, are placed in chambers. Chambers are connected through a connecting hole of the finite length. Electrical discharge is created in the connecting hole between electrodes and generates chemically active species, which expand into the water flowing through the apparatus. Due to action of primary chemical and physical processes initiated by the discharge and subsequent secondary chemical processes taking place in an aqueous solution present in the chambers water treated by this apparatus is decontaminated and disinfected.
