SELECTING ENGINEERING SOLUTIONS FOR WATER TREATMENT MODULES IN THE OIL AND GAS FIELD AREAS OF THE FAR NORTH

. The article provides data on engineering solutions for water treatment modules being part of the utility and drinking water supply complexes in small settlements located in the Far North, where low-turbidity, high-colored waters serve as the surface sources of water supply. These sources include the river networks of the Ob River (including the southern area of the Gulf of Ob, Kara Sea), Pur River, and Taz River (including the Gulf of Taz, Kara Sea). Methods. We present an analysis of the applied water treatment technologies, reagents, and materials, as well as water processing modes, and establish the reasons for the unsatisfactory performance of the operated water treatment modules implementing physical-and-chemical methods of water purification. Results. It is found that the use of granular materials as media for rapid filters (AS, MS, MZhF autocatalytic sorbents) is not very effective since they are intended for the purification of colorless groundwater with a high content of dissociated compounds of divalent iron and manganese. Throughout the year, the modules operate without account for seasonal fluctuations in the qualitative composition of the source water and with reagents that have lost their active properties. Conclusion. Based on the conducted studies, we propose engineering solutions for the purification of low-turbidity, high-colored waters of surface sources, making it possible to achieve target quality indicators complying with the best available technologies.
