[Reliability of the disinfecting action of pulse electrical discharges in water treatment].

The irreversibility of the damaging action of pulse electric discharges (PED) on microorganisms in the process of the disinfection of water was studied. The experiments with standard E. coli culture showed that bacterial cells remaining alive after being subjected to the action of PED eventually died the sooner, the higher the temperature of the medium was. In any of the "blind passages" made within 7 days no growth of the test microorganism was observed. The use of enriched fluid media and 10-day incubation did not ensure the preservation of proliferation ability of the cells after the action of PED with the parameters used in the experiment.
