| Summary: | The urgency of the conducted studies is dictated by the problem of Urban Territories’ sub-surface waters purification providing in the Republic of Sakha (Yakutia) population with drinking water, which can be partly solved by involving the sub-surface waters of the Yakutian artesian basin in the domestic and drinking water supply systems. The chemical composition feature of the under-ground waters under consideration, which substantially complicates their widespread use for domestic and drinking purposes, is the increased content of lithium, fluorine and sodium. The main research objective is to develop an effective method for clearing the sub-permafrost waters of the Yakutian artesian basin from lithium compounds, which can be used in water treatment systems for domestic and drinking purposes. As a result of the experimental studies on the sub-permafrost water purification of casting by the ion exchange method, its content reduced from 0.5 to 0.01 mg / l, which fully met the requirements for drinking water. On the basis of the results obtained, a comprehensive scheme for the sub-permafrost waters purification of the Yakutian artesian basin from lithium, fluorine and sodium was developed for the purpose of household and drinking water supply. |
