STUDY OF THE PROCESS OF CLEANING WATER-CONTAINING IRON SOLUTIONS USING OZONE TECHNOLOGY

Abstract

In this scientific research work, the problem of studying the process of removing water – containing iron solutions with an Etro-04 device based on high-frequency corona discharge is considered. In the research work, a special Etro – 04 ozonator device was developed for the oxidation of heavy metals, i.e. chemical pollutants contained in water. Work on testing the device was carried out in order to clean the underground water “Aktogay wide place”. During the research work, various painful heavy metals were found in the composition of the source water that do not meet the maximum permissible (MPC). For example, iron (Fe2+, Fe3+) solutions met 2.00 – 2.2 mg/l. This means that the MPC is 7 times more than the specified value. In order to solve this problem, research work was carried out. During the technological process, various amounts of ozone (O3) were released into the water, the amount and effective economic indicators of which were determined. In the same way, the effective time of the oxidation and cleaning process was determined. During the research process, an algorithm of theoretical calculations was developed and a mathematical model was given to bring 1m3 of groundwater to a fixed indicator. In order to determine the effectiveness of cleaning the iron contained in the water by the concentration of ozone and the filter load, water filtration works were carried out at different speeds of 5.5 – 9.5 m/h. For example, with an ozone content of C =100 mg/l and a filtration rate of 9.5 m/h, you can see that the iron content in water is purified by 30% percent, 8.5 m/h – 55% percent, 7.5 m/h – 77% percent, and 5.5 m/h – 90% percent. Experimentally and theoretically, it was found that Iron solutions with water content were purified by 98 – 98.7% percent, respectively, with an ozone concentration of C = 500 – 600 mg/l and a filtration rate of 5.5 m/h.
