The oxidation of hydrogen sulfide in geothermal steam condensate by hydrogen peroxide was tested in a specially designed, continuous flow bench scale treatment system. The effectiveness of the treatment was monitored using a silver/sulfide specific ion electrode in a technique developed specially for this study. The effects of pH, treatment ratio, and catalyst on the oxidation reaction were studied. The results of the study were used to operate a pilot plant treatment system to determine optimal peroxide treatment conditions. The bench scale studies identified iron as the catalyst of choice and indicated that the pilot plant testing could concentrate on the pH expected in the full scale plant, pH 8. The bench scale studies further indicated that pilot plant testing would not need to include hydrogen peroxide to sulfide treatment ratios of greater than 4:1 and that lower ratios might be adequate.
