Optimizing the energy consumption of ozone generator and plasma generator in water decolorization and disinfection

The use of ozone in water and waste water treatment and health and food industries has found an exponential trend due to its compatibility with the environment. Ozone, which is a triatomic molecule of oxygen, is a strong oxidant and unstable free radical that quickly combines with other substances or turns into oxygen after decay. The production of ozone with electricity is simple, but the main challenge is the high cost of electricity consumed by ozone generators. The purpose of this research was to design and build ozone generating devices with less electricity consumption.

In this research, after computer simulation, various types of ozone generators and plasma generators were made with the approach of reducing energy consumption. Since all these equipments are composed of three components, frequency increasing circuits and voltage increasing transformers and reactor based on electric discharge in gas, after designing and simulating all three parts separately, we proceeded to build a complete pilot device for color removal. And the water was disinfected.

by making an ozone device that consumes as much as a 30-watt low-power light bulb and by injecting this device's ozone for 5 minutes into water with methylene blue color pollution as an indicator of color pollution and Escherichia coli as an indicator of microbial pollution , while decolorizing, 99% microbicide was achieved in water.

In order to produce ozone from cold plasma, integrated construction and simultaneous optimization of the circuit, transformer and reactor have been done. According to the high frequency inverter designed in this research, the ozone production reactor works at a lower temperature.
