Abstract: The unique properties of water explain its wide distribution in various spheres of life: for drinking water supply, in agriculture and for industrial purposes. Energy processes in the atmosphere and hydrosphere are largely due to the thermo physical properties of water. The lack of fresh water necessitates the use of such alternative sources of water supply as mine water. When using these waters in industry, scale formation is a limiting factor. The main scaler is calcium carbonate, the intensity of the formation of which depends on the carbonate index – the product of the concentrations of calcium ions and alkalinity of hydrocarbon water. The formation of calcium carbonate deposits begins already in the process of pumping mine water from underground horizons. The data on the increase in pressure drop in the stakes and additional costs of funds for pumping mine water as a result of scale formation in pipelines are given. One of the alternative solutions to reduce the use of fresh water is the use of treated mine water to feed heating networks. A comparison of two technologies of water softening using strongly and weak acid cation exchangers is given. The main advantage of using weak-acidic cation exchangers is that water softening ensures a stable water quality, saline effluent discharge is reduced by a factor of 4–5, and when water is treated, both scale ions are removed: the calcium cation and the hydrogen carbonate ion.
Keywords: fresh water, mine water, softening, drains, cationite, scale formation, becoming.
