Joint with Kyivvodokanal testing of the possibility of using pulverized activated carbon in water treatment

In August 2024, the Seim River (a left tributary of the Desna River) in the Sumy and Chernihiv regions and the Desna River in the Chernihiv region were massively polluted by the discharge of highly concentrated industrial wastewater into the Seim River in the Kursk region of Russia.

The deterioration in the water quality of the Desna River, which is the primary source of water supply in Kyiv (supplying about 70% of the capital’s population), may negatively affect the technological process of water treatment, which will lead to the need to use additional reagents at the Desna Water Supply System in Kyiv.

To eliminate possible consequences of the Desna River pollution and bring drinking water quality indicators to the requirements of Sanitary and Epidemiological Norms 2.2.4-171-10, Kyivvodokanal tested the possibility of using pulverized activated carbon (PAC), Silcarbon CW 20, and TH 90-6 and Norit SA Super and W 35, in water treatment. The assessment of the use of PAC to eliminate the possible consequences of pollution of the Desna River and bring drinking water quality indicators to the requirements of Sanitary and Epidemiological Norms 2.2.4-171-10 was carried out by specialists of the Laboratory of Natural and Drinking Water Hygiene of the SI “IPH NAMSU” at the suggestion of Kyivvodokanal. Based on the analysis of the test materials, it was concluded that the use of activated carbon in the source water treatment technology (together with coagulant and chlorine) is an effective measure to remove unpleasant odors from water and bring the quality of drinking water to the regulatory values, and appropriate recommendations were made to optimize the water treatment process with surfactants.
