“…In regards to this, the object of this analysis is the sedimentation of waters from drill hole B-4 (Sijarinska spa, depth 1232 m) and drill hole VG-2 (Vranjska spa, depth 867 m). Although these locations are relatively close by, geographic characteristics and chemical composition of these waters are different and they have different physicochemical parameters [7][8][9][10][11].…”

A comprehensive analysis of physicochemical parameters in geothermal waters from the sites in Sijarinska spa (drill hole B-4) and Vranjska spa (drill hole VG-2) in order to investigate their tendency to form deposits in the pipe installation is presented. Both drill holes, B-4 and VG-2 possess utilization capacity of 30/27 L s-1 with water temperatures 75-90 °C. VG-2 water does not show any tendency of (or shows very little) sedimentation compared to the B-4 water. The behavior of the geothermal water from the B-4 hole was examined in real conditions of water flow through the pipe installation in Sijarinska spa. The results of geochemical analysis of B-4 water show that aragonite is the predominant mineral in the sediment (98%) with small amount of calcite, vaterite and anhydrite.

Geological complexity of the territory of Serbia is a world curiosity: six main geo-tectonic 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 96ºC, or an overall heat energy of 78.40 MWt. Feasibility of additional energy utilization of thermal water in spas is generally considered

An estimate of deep groundwater temperature is necessary for the research and utilization of this geothermal resource. Geothermometers are based on the temperature relation of some chemical reactions or the solubility of some minerals. Researchers mostly use silicon-based (quartz, chalcedony, amorphous silica) and cation-based (Na-K, Na-K-Ca, Na-K-Mg, and so forth) geothermometers. Temperatures of some prospectively abundant geothermal water resources in Serbia are estimated using the silicon-based geothermometers. In the absence of hot water resources, temperature of deep thermal groundwater has to be estimated and considered for power generation with the Kalina or the Rankine binary cycle. Best thermal waters (temperatures from 130°C to 160°C) for the purpose are located in the spa of Vranjska Banja, followed by Kuršumlijska, Sijarinska, and Jošani~ka spas and Bogati} of Ma~va. Pumped at the present rate of 200 l/s, the mentioned sources may generate 70 MW t , of which some 30 MW t the Vranjska Banja alone. Total power (for the five tested resources) is estimated at about 2200 TJ per year.
