Construction of a low budget ozone generator prototype

Abstract

Industries advance causes serious damages to environment, these impacts are mainly visibly due to pollution emitted as gases and effluents. However, most companies are looking for alternatives that are both fast and efficient in reducing environmental degradation. Regarding effluents emission, there are recent researches that seek methods to treat wastewater effectively in industrial processes and, among these methods, ozone use stands out. This paper presents the development of a low cost sustainable ozone generator prototype with the purpose of producing gas by using corona effect, formed by high voltage generators using photovoltaic panels as power supply. In its construction recycled materials were used. The project aimed to use electronic concepts as a way to increase the apparatus efficiency, looking forwards to improve the gas application in liquid effluents treatment. After the prototype construction, ozone production was certificated by bubbling out the reactor directly into a solution of soluble iodine / potassium iodide. Ozone presence was observed by the solution coloration changing from colorless to intense dark blue. At the end of the work, experiments were carried out at the treatment of water from fish farms, in which the gas performance in the regulation of quality indicators, such as salinity, pH, dissolved oxygen and Electrical conductivity.
