CONDUCTING THE EXPERIMENT ON WATER DISINFECTION BY TREATING WITH HIGH-VOLTAGE DISCHARGES
Introduction: the article is devoted to the conducting of a three-factor experiment on water disinfection by treatment with high-voltage discharges, formed to achieve the electrohydraulic effect, in order to find the optimal conditions and rules for the processes under study. Materials and Methods: in the study, high-voltage equipment with an electrohydraulic discharger, EnSURE luminometer (Hygiena) for measuring the level of water hygiene and its solutions, test tubes for determining the total number of ATP in AquaSnap Total water (AQ100X) are used as materials and equipment; in the study, the methods of multifactor planning are used as methods, the annex to certificate No. 54301 on the approval of the type of measuring instruments, the measurement technique with the EnSURE luminometer (Hygiena). Results: factors that adequately describe the process, operating voltage, capacitor capacitance and number of discharges are determined; selects the regression equation; a plan of a multifactor experiment is drawn up, a conditional zero level and units of variation of each of the factors are selected; substantiates the source of water samples for research. Discussion: а matrix for planning the exit of the level of microbiological contamination of a water sample is being developed; the required experimental number of experimental variants is argued; the output is substantiated as specific relative to the loading volume of the electrohydraulic device; the search for optimum factors of influence on the process. Conclusion: a full three-factor experiment is carried out; the influence of design parameters and modes of influence of an electrohydraulic installation on the properties of water as a result of the generation of high-voltage discharges is investigated; experimental data on microbiological contamination of a water sample is detected, which, according to the analysis of the data obtained, is reduced, which can serve as a basis for the potential use of high-voltage discharges as a method of preparing water under irrigation conditions in greenhouses; the optimum ratios of factors for disinfecting a pond water sample from an artificial source are identified: an operating voltage of 19.9 kV, a capacitor capacity of 0.1445 microfarad and the number of discharges 2 861 pieces.
