Русский Experimental studies of the effect of ozonation on the water treatment process in the design of an ozone generator
Abstract
Purpose – this article discusses a new approach to the process of ozonation of water from the point of view of its hardware design for water treatment plants of centralized water supply. At the same time, it is shown how the quantitative use of ozone in water treatment (dose) depends on the chemical composition of water and is determined in each specific case and requires determining its place in the technological scheme. The operating characteristics of ozonators, which were used to determine design requirements and find operating modes, are considered in detail. The purpose of these studies was to conduct pilot tests to determine ozone doses and evaluate the effectiveness of the ozonation method at a number of water supply stations, including at the WTF of Tyumen, the source of the Tura river.
Methods: in the conducted studies, computational, theoretical and experimental methods were used to determine the minimum voltage at which the discharge in the discharge gap "burns" and power-amplitude voltage curves were constructed. Since the specific energy is the intensive parameter that determines the kinetics of ozone synthesis, the ozone concentration at the outlet of the ozonator and its dependence on the experimental parameters were studied during the experiments. The developed methods were used in determining design solutions at water treatment plants of the Russian Federation.
Results: it was shown that the discharge ignition voltage determines the geometry of the ozone generator itself and the pressure in the discharge gap. As a result of the research, it was revealed that the concentration of ozone at the outlet of the ozonator depends almost linearly on the specific energy and the effective dose of ozone is a key parameter in the hardware filling of ozonator complexes.
Conclusions: the projects carried out with its use received a positive conclusion of the state expertise. The equipment developed taking into account the data obtained experimentally is successfully operated as part of the ozone absorption units of water treatment facilities.
