INVESTIGATION OF WATER DISINFECTION PROCESSES USING PULSE ELECTRIC DISCHARGE

As a result of Russian military aggression in the south-eastern region Ukraine, water supply pipes and structures centralized systems were destroyed, therefore was practically stopped. The solution to problem can be use mobile treatment stations which local sources water: canals, lakes, ponds, or underground water. A feature technologies field is need reliably ensure process disinfection. Existing disinfection have low efficiency, taking into account growing number chlorine-resistant microorganisms, therefore, implementation alternative methods during urgent. One these liquid by electric current discharge. results research on different types surface Kyiv contaminated with E. coli (Escherichia (E. coli)) are described. carried out laboratory setup circulation pump an ejector-type reactor integrated electrodes where water-air mixture formed through discharge passes. discharges initiate formation various highly reactive chemicals such as radicals (OH•, H•, O•) molecules (H2O2, H2, O2, O3). All physical chemical processes that occur action short-term relatively long-term oxidants. study influence concentration microorganisms speed completeness technical (tap) addition washings from two tubes test culture reaction tank, provided initial equal 3.4∙106 CFU/cm3. Water for 30 seconds reduced 5.4∙104 After 1 minute this indicator decreased 1.7∙102 after 3 minutes value 5.2 CFU/cm3 recorded samples, is, treated had indicators pure Experiments proven effectiveness plasma liquids high microorganisms.
