Today, the topic of the global problem of providing the population with water suitable for consumption is investigated regularly, and every year the urbanization of cities and, consequently, industrialization grows, and when water is used for technical needs, it must be treated to the normative maximum permissible concentrations, which is an energy- and resource-intensive process. To effectively treat wastewater from various pollutants, industrial wastes are increasingly being used, which show high efficiency of wastewater treatment and are inexpensive. It is the study of the specifics and peculiarities of the use of production wastes that is the purpose of this study. During the research, methods such as analysis and experimentation were used. The article proposes to use carbonate sludge as an adsorbent – a large-tonnage waste from chemical water treatment plants at thermal power plants. The study is devoted to the presentation and analysis of the results obtained in the development of a sorption material known as granular modified carbonate sludge (GMCS). To evaluate the interaction of carbonate sludge with phenol, an adsorption isotherm was constructed. In addition to the isotherm, the study also included the construction of an adsorption output curve under dynamic conditions. Based on the data, the environmental efficiency of wastewater treatment from phenols was calculated. This calculation considered the initial concentration of phenol in the wastewater, the amount of phenol adsorbed by GMCS, and the resulting decrease in the concentration of phenol after treatment. The environmental impact of using GMCS for phenol removal was determined by quantifying eco-efficiency. The practical significance of this research is that it can help to reduce the pollution of water systems, improve sanitary conditions, and protect human health and ecosystems.
