Optimization of the process of colored water chemical treatment in characteristic periods of the year

Summary

Significant seasonal changes in the water quality in natural water supply sources cause problems in the purification of drinking water at a water treatment plant. This is particularly true in the process of purification of low-turbid colored water with a high concentration of organic substances, at low water temperatures. During flood periods, the pollution load on the treatment facilities increases significantly; as a result, the quality of treated water deteriorates, and it is rather difficult, and in some cases impossible, to ensure meeting the standards for some indicators. The problem is solved by applying various methods and creating conditions for the coagulation process, taking into account seasonal changes in the quality of the raw water and technological options for the purification at the water treatment facilities.
