Abstract
A three-factor experiment is conducted on the disinfection of water by treatment with high-voltage discharges formed to achieve an electro-hydraulic effect, in order to detect optimal conditions and rules for the course of the processes under study. In the study, a high-voltage installation with an electro-hydraulic spark gap, an EnSURE luminometer (Hygiena) for measuring the level of hygiene of water and its solutions, test tubes for determining the total number of ATP in AquaSnap Total brand water (AQ100X) are used as materials and equipment. The influence of design parameters and exposure modes of an electro-hydraulic installation on the properties of water as a result of the generation of high-voltage discharges is investigated; experimental data are revealed for measuring the level of microbiological contamination of the water sample, which, according to the analysis of the data obtained, is reduced, which can serve as the basis for the possibility of the potential use of the effects of high-voltage discharges as a method of preparing water under irrigation in greenhouses; optimal ratios of factors for disinfecting a pond water sample from a source of artificial origin are revealed: operating voltage 19.9 kV, capacitance 0.1445 μF and the number of discharges 2861 pieces.
Highlights
Prevention of diseases of plants grown in greenhouse systems is no less significant for crop productivity than building and maintaining a balanced chemical composition and content of macro- and microelements in nutrient solution [1]
The principle of operation of the aforementioned luminometer is to determine the level of adenosine triphosphate (ATP) - a universal energy molecule found in all plant, animal and bacterial cells, including yeast and mold
The generation of high voltage discharges is ensured by the developed high voltage installation
Summary
Prevention of diseases of plants grown in greenhouse systems is no less significant for crop productivity than building and maintaining a balanced chemical composition and content of macro- and microelements in nutrient solution [1]. The use of drainage water, water from rivers and open reservoirs for irrigation of plants without the use of sterilization and disinfection means can lead to infection and the spread of infection in leaves, stems and fruits. Nutrient solutions for irrigation of greenhouse crops, as such, are a favorable environment for the development of microorganisms that provoke various diseases of greenhouse plants. Through the nutrient solution during irrigation, the keel, black leg, white rot, gall nematode, strick, late blight and other diseases can be transmitted. Whatever the cause of infection, the disease worsens the growth and development of the greenhouse crop, resulting in a decrease in fruiting.
