Recycling of iron-containing deposits – the main way to increase the efficiency of water-protective measures on the territory of the Tom lower course

The paper presents the investigation of iron-containing deposits at water treatment in the Tomsk water supply intake. The chemical composition of the waters facilitates the formation of deposits in a large amount on the territory of the Tom lower course. A large ground water deposit is located here, and it is used for Tomsk water supply. Currently, the deposit obtained at water treatment is discharged in the Kislovka, and this practice causes a serious environmental problem. The ways of deposit usage are offered in the paper, which will sufficiently increase environmental protection measures on the territory of the Tom lower course.
