The present article considers disinfection of water and water resources from pathogenic bacteria like E-coli by a high-voltage electro pulse processing. The technique of determination of microorganisms concentration before and after the pulsed impact is shown. Experimental results on the influence of different discharge types (crown, spark), of the processing time (number of discharges), of electric parameters of a high voltage generator (tension, polarity, charging capacity) and of the initial concentration of microorganisms on changes in their quantity after an electro pulse impact are presented. It is found that an inactivation level of microorganisms is significantly depended on the type of a discharge, processing time, and their initial concentration. The data on most effective electro pulse processing modes of the water medium are given.
