The chemistry of geothermal waters: its effects on exploitation

“…Rimstidt and Barnes (1978) describe two types of apparatus designed for laboratory testing of the scaling POtential of the fluid from the Magmamax # 1 well. Bishop and Bricarello (1977), Pepper and Larkin (1979), Anastas et al (1979) and Harrar et al (1979) give details of a pilot plant known as the Geothermal Loop Experimental Facility (GLEF), which was installed on the Niland geothermal field. Five years of research using this apparatus has led to the development of methods for tackling crucial problems related to the very high salinity of the fluid, and to the construction of a 26,000 kWe power plant (McCabe, 1981).…”
