One of the applications of ozone for wastewater treatment is the destruction of difficult-oxidizing organic contaminants, including dyes. An important stage of development of water purification technology is the determination of the required degree of pollution destruction, effective doses of ozone and the period of water treatment. For example, in some cases when the dyes are degraded in textile sewage, the color reduction occurs with a slight decomposition of the organic substance of the dyes. The purification process is controlled by several indirect indicators, such as oxidizability, total organic carbon content, etc. We have conducted experimental researches and have studied the material balance of the ozonation process for wastewater containing dyes. Generalized method for determination of the consumption of ozone in the oxidation of contaminants in sewage waters and the technological indicator “chemical demand of ozone” are proposed. The method is quite universal and allows, while carrying out trial ozonation of water, to obtain dependence of ozone consumption for the processes of pollution destruction and determine the required specific dose of ozone.
