The problem of removing silica from geothermal brine is considered. The colloidal and chemical properties of the brine are studied. Silica precipitation by electrocoagulation is described, and the process parameters are optimized. Factors in the profitability of the multipurpose utilization of the hydrothermal heat carrier are discussed.
