Abstract:

The water from geothermal reservoir 'Los Azufres' in Michoacan, Mexico, is characterized by its high content of chloride, silica, borum and arsenic. Due to the high concentration of such elements and the restrictions on disposing of them, an alternative to recover salts by means of evaporating ponds was analyzed. In order to predict the pond evaporation and salt concentration, a numerical model was developed. Data from meteorological conditions of the site, experimental results on salt evaporation, and an energy balance of the pond-environment lead to preliminary estimates of pond capability to recover salts.
