Desalination of Geothermal Water for Its Application in the Irrigation Sector

The agricultural sector, which heavily depends on water, must develop better water management techniques and look into possible ways to meet supply and demand due to issues related to water scarcity and the need for a profitable and sustainable agri-food chain. Geothermal groundwater can be used to create both electricity and heat. As a result of its high ionic content, harvested energy can be recovered and then used for irrigation. Most geothermal fields can be found in rural areas where farming is practiced. The energy expenditure of agricultural desalination is higher because of the necessity of additional post-treatment procedures. Meeting energy needs with fossil fuels is becoming increasingly costly, and its associated greenhouse gas emissions are damaging the environment. This highlights the need to work to incorporate non-conventional energy sources into the desalination process. The use of geothermal heat for desalinating water is a renewable energy source that is thoroughly examined in this chapter. The introduction of possible geothermal energy integration with desalination technologies is also covered, along with the desalination of geothermal water for irrigation.
