Practical experience in retrofitting existing water treatment plants due to stricter regulatory requirements for drinking water quality

The article discusses the problems related to the entry into force of the updated sanitary and epidemiological standards for the quality of drinking water in centralized water supply systems. The authors analyzed the key aspects of applying a comprehensive strategy for selecting and implement-ing advanced methods to improve the efficiency of natural water treatment, based on current domestic and foreign experience, using the example of a large water treatment facility in Volgograd. Compara-tive data on the functioning of the water treatment complex under consideration are presented, with the identification of the main indicators of pollutants for which there are exceedances of permissible values in accordance with current regulatory requirements. Technical approaches aimed at accelerat-ing individual stages of water purification in order to achieve the required quality of drinking water using advanced technologies of the current time are described, while not involving the construction of new facilities, but only using existing production facilities and additional purification methods with minimal capital investment
