The dependence of the current and voltage on time in discharges in gas bubbles in water used for its purification is studied experimentally. It is shown that at the front of the current pulses with discharges in bubbles there is a kink, after which the rate of current increase sharply increases. The frequency of discharges in bubbles is 10,000 pulses / s at a voltage amplitude of 8 kV on the reactor-the load of the experimental setup generator and currents of 0.2 A in a high-voltage discharge circuit with discharges in gas bubbles. A high degree of purification of water used in coke production was obtained from phenols and thiocyanates. The possibility of improving the organoleptic parameters of water and reducing the biochemical oxygen consumption by it is shown. References 12, figures 5, table 1.

The processes in the discharge circuit of a powerful high-voltage pulse installation with three multi-gap spark gaps operating in parallel are experimentally investigated. Oscillograms of voltage and current pulses at the load in the form of three reactors are obtained with running water. The discharge processes are compared when using in the discharge circuit three multi-gap dischargers and three reactors connected in parallel, on the one hand, and one such discharger and one reactor on the other. The regimes of synchronous discharges in gas bubbles were obtained in three reactors, which ensured the complete inactivation of the E.coli in water with an initial concentration of 10 6 CFU/cm 3 (CFU is a colony-forming unit).
