One of the urgent problems of modern civilization is the provision of the population with highquality drinking water. According to the World Health Organization (WHO), at least 5-10 % of the population suffers from waterborne diseases. According to the Federal Service for Supervision of Consumer Rights Protection and Human Well-being in nine cities of the Siberian Federal District, the influence of water quality on the formation of population morbidity (from 7,7 to 41,0 %) has been established. Analysis of the data presented in the State reports on the state and protection of the environment of the Irkutsk region showed that in the surface waters of the region there is a systematic excess of the maximum permissible concentration (MPC) for phenol, and in some controlled areas for chloroform. One of the main components used in the production of various non-alcoholic products is water. Various organic substances, such as phenols, petroleum products, halogenated derivatives of hydrocarbons, according to the requirements for the quality of water used for the preparation of soft drinks, should be absent. Therefore, the purpose of the study was the use of various adsorption systems for wastewater treatment in the Irkutsk region for drinking water supply and the production of soft drinks. Used the adsorption method. The studies were carried out on model aqueous solutions, both of individual substances and in their joint presence. Mathematical modeling of the sorption process under dynamic conditions has been carried out. As a result of the studies carried out, the possibility of using charcoal for wastewater treatment has been proven. Pretreatment of activated carbon with hydrochloric acid practically does not affect the adsorption of chloroform, but leads to an increase in the adsorption of phenol. Hydrochloric acid helps to remove iron ions from the pores of the sorbents. A decrease in the degree of water purification from phenol with an increase in pH leads to the suppression of adsorption. The effect of phenol and chloroform on the value of adsorption has been established. The sorption process is limited by external mass transfer. The discrepancy between the calculated and experimental output curves of phenol and chloroform sorption from individual solutions and in their joint presence is calculated.
