Some aspects of conditioning high-color river waters of the Far North

Summary

Some aspects of water conditioning of the Solza River at the water treatment plant in Severodvinsk are considered with an analysis of the quality of natural water for the period 2020–2023. The results of statistical processing of initial data on the river water quality are presented. The features of the chemical treatment of river water containing a high concentration of organic substances, and with the composition varying in dependence to the season, are considered. Based on statistical processing of the data for the 2020–2024 period in terms of color and permanganate index, the range of the color coefficient variation was determined. In the course of studies, the optimal pH range was established to provide for the minimum concentrations of residual aluminum in purified water.
