TL;DR: In this paper, the effect of regenerant type and regeneration conditions has been investigated to find the optimal operational conditions for minimizing the regenerant consumption, and a study for removing boron from Kizildere / Turkey geothermal wastewater using the Boron selective resin Amberlite FRA-743 was presented.
Abstract: Geothermal energy is an alternative renewable energy resource that has proven itself technically and economically feasible as a nonpollulanl electric power source. The Denizli-Kizildere geothermal energy region is the first major geothermal energy resource project in Turkey, with an estimated potential of 200 MW. The use of the geothermal potential of the region depends on removal of its high boron content, since waste brine is discharged into the nearby Bilyuk Menderes River. This article represents a study for removing boron from Kizildere / Turkey geothermal wastewater using the boron selective resin Amberlite FRA-743. The effect of regenerant type and regeneration conditions has been investigated to find the optimal operational conditions for minimizing the regenerant consumption.

TL;DR: Most direct use applications use geothermal fluids in the low-to-moderate temperature range between 50° and 150°C, and in general, the reservoir can be exploited by conventional water well drilling equipment as mentioned in this paper.
Abstract: Direct or non-electric utilization of geothermal energy refers to the immediate use of the heat energy rather than to its conversion to some other form such as electrical energy. The primary forms of direct use include swimming, bathing and balneology (therapeutic use), space heating and cooling including district heating, agriculture (mainly greenhouse heating and some animal husbandry), aquaculture (mainly fish pond and raceway heating), industrial processes, and heat pumps (for both heating and cooling). In general, the geothermal fluid temperatures required for direct heat use are lower than those for economic electric power generation. Most direct use applications use geothermal fluids in the low-to-moderate temperature range between 50{degrees} and 150{degrees}C, and in general, the reservoir can be exploited by conventional water well drilling equipment. Low-temperature systems are also more widespread than high-temperature systems (above 150{degrees}C), so they are more likely to be located near potential users. In the US, for example, of the 1,350 known or identified geothermal systems, 5% are above 150{degrees}C, and 85% are below 90{degrees}C (Muffler, 1979). In fact, almost every country in the world has some low-temperature systems; while, only a few have accessible high-temperature systems.

TL;DR: The Tattapani Geothermal field produces + 1800 1pm thermal water of 100°C from five production wells as discussed by the authors, which can sustain electricity production of 300 kWe by using a binary cycle power plant.
Abstract: The Tattapani Geothermal field produces + 1800 1pm thermal water of 100{degrees}C from five production wells. The hot water production can sustain electricity production of 300 kWe by using a binary cycle power plant. The heat energy of effluent water from power plant can be utilized for direct heat utilization on horticulture, aquaculture, cold storage, silviculture etc; to augment the economics of the power plant be spot can be developed as a centre for tourist attraction by constructing botanical park, greenhouse, geyser show and crocodile farm. The direct heat utilization shemes can be planned in cascading order to achieve maximum utility of thermal water. Additional deep drilling is essential for optimum commercial utilization of the Geothermal energy. The direct heat utilisation shemes along with binary cycle power plant may help in development of the geothermal energy and boosting the economy of this region.
