Boron Removal From Geothermal Waters by Electrocoagulation

Journal of Hazardous Materials, 2008
Most of the geothermal waters in Turkey contain extremely high concentration of boron when they are used for irrigation. The use of geothermal waters for irrigation can results in excess amount deposition of boron in soil. On the other hand, a minimal boron concentration is required for irrigational waters.

Geothermal Water Management

, 2018
In the agriculture and agri-food chain industries there is a strong nexus between food, energy and water as it consumes about one-third of the global energy and 80-90% of the world’s freshwater production; freshwater production consumes about 15% of the ...

Modelling of a decarbonation reactor for geothermal waters: application to geothermal waters of Chott El Fejjej

Desalination, 2006
The geothermal waters exploitation infrastructures in Chott El Fejjej (Tunisia) are constantly being damaged by a scaling phenomenon. Experimental work has been carried out on a new kind of decarbonation reactor: the open double partition reactor (RODP), which may be used in the construction of a new plant at the site of Chott El Fejjej.

The value of heat and geothermal waters

Quarterly Journal of Engineering Geology and Hydrogeology, 2022
Evaluation of proposed geothermal projects often requires a value to be assigned to waterborne geothermal heat or geothermal fluids. A methodology for valuing low-enthalpy warm fluids (<90°C) is presented: the method uses a reference price for sale of waterborne district heating at a relatively high temperature (in this paper, we have assumed 70°C),

Molybdenum in icelandic geothermal waters

Contributions to Mineralogy and Petrology, 1985
Molybdenum concentrations in Icelandic geothermal waters lie in the range 1–70 ppb. Warm waters and dilute high-temperature waters which contain high concentrations of sulphide are lowest in molybdenum. No correlation is otherwise observed between molybdenum concentrations and temperature. Surface waters and cold ground waters do not contain detectable

Water injection into a geothermal reservoir

Journal of Applied Mechanics and Technical Physics, 2002
The previously obtained criterion which distinguishes water injection regimes accompanied by vaporization of injected water or vapor condensation is extended to the radially symmetric problem. The effects of cold liquid injection rate and the initial temperature, pressure, and capacity of a geothermal reservoir on hydrodynamic and temperature profiles ...

Material use of geothermal waters

2021
The production of geothermal energy requires the circulation of large volumes of thermal brines reaching up to several 100 L/s. These brines are the product of long-time water-rock interactions at a high temperature and depth leading to various water compositions.

Evaluation of geothermal water and assessment of corrosive and scaling potential of water samples in Tulsishyam Geothermal Region, Gujarat, India

Environmental Science and Pollution Research, 2023
The purpose of this study was to evaluate and analyse the water quality in the Tulsishyam region in terms of corrosive and scaling properties. Thermal water samples (TWS), groundwater samples (GWS), and riverwater samples (RWS) were collected and analysed for a variety of geochemical parameters in various locations throughout the Tulsishyam region. The

Chemistry of Geothermal Waters

1980
At least 95 percent of hot spring waters is meteoric, precipitation from rain and snow, and originally free of mineral content. Any remainder could be magmatic. The substantial quantities of chemicals they carry when they reappear at the surface are picked up during their circuitous subterranean passages. The extreme diversity in the composition of hot

Mineral and geothermal waters of Slovakia

GeoJournal, 1995
From 1955 to 1985 an intensive hydrogeological survey has been carried out in Slovakia, in order to ascertain the conditions of forming mineral and geothermal waters in various geological structures and to find new sources of the afore-mentioned waters.
