ABSTRACT:
Condensate of steam derived from a geothermal brine is treated to enhance its utility as wash water for a brine filter. The condensate is sprayed into a tank in the presence of air to effect substantial oxidation of oxidizable sulfur species contained therein, and the pH of the condensate is adjusted to be within about 1.0 pH units of the pH of the brine. Such treatment substantially extends the life of the filter media used in the brine filter.
