Abstract :Hot spring waters are rich in terms of minerals. Since there are dramatic changes in thermodynamic parameters in geothermal power plants, such as a decrease in temperature and pressure, severe precipitation occurs throughout the system components in an uncontrolled manner. There are three main chemistries in deposits: carbonates insert ignore into journalissuearticles values(mainly calcium carbonates);, silicates insert ignore into journalissuearticles values(metal silicates);, and sulphides insert ignore into journalissuearticles values(antimony sulphide-stibnite);. Energy harvesting is remarkably reduced out of the insulating nature of the deposit. Various actions need to be taken to mitigate this undesirable issue of scaling in geothermal systems. Geothermal systems are in fact quite complex, and the composition of brine and, accordingly, the chemistry of the deposit are not identical. Therefore, each system should be studied individually, and a tailor-made remedy should be developed. In this overview, the types of deposits in terms of chemistry and the actions insert ignore into journalissuearticles values(pH modification or antiscalant dosing); that should be taken to reduce scaling are mentioned, and potential chemistries of antiscalants are given.
