HYDROGEOTHERMAL RESOURCES IN SPA AREAS OF SERBIA, Main Properties and Possible Improvement of Use

Abstract

Geological complexity of the territory of Serbia is a world curiosity: six main geotectonic regions and tens sub-regions are delineated in a small area of 88,000 km2. Geologic origin and regional structure of some areas has long been the subject of discussion. Notable magmatism and associated tectonic events in the Earth's crust provided for a fairly large hydrogeothermal resource potential, which is manifested in more than 250 warm (mainly mineral) springs and more than 100 hydrothermal wells. Thermal springs and wells together discharge some 5 m3/s. This potential is used in part for balneal therapy (waters differ in temperature and chemical composition) in the spa areas of Serbia. The amounts of thermal water unused therapeutically or the amounts of heat energy from unused geo-thermal water may be used in almost all spas for space heating/cooling and thus increase the efficiency of the thermal water energy utilization. This also will be cost-effective, reduce emission of noxious gases, and improve the environmental--health image of the resorts. The hydrogeothermal resources are described for 29 spas with 700 l/s total discharge capacity of water temperature between 25 °C and 96 ºC, or an overall heat energy of 78.40 MWt. Feasibility of additional energy utilization of thermal water in spas is generally considered.
