    摘要: A method of purifying gluconate-containing brine is described which comprises first removing transition metal cations and other impurities by passage of the brine through a first ion exchange resin. The brine is then passed through a second ion exchange resin to effect removal of alkaline earth metal cations. In a third step the brine is treated with a carbonaceous adsorbent to remove impurities introduced by the ion exchange resins, as well as to effect removal of quaternary ammonium salts such as chloromethyl triethylammonium chloride. Methods for the regeneration of the carbonaceous adsorbent are described.

    摘要: A chlorination system in which brine is converted to sodium hypochlorite by an electrolyser. Brine (1) fed to the electrolyser (3) is passed through a filter (2) which is capable of adsorbing bromine or hypobromous acid. Some of the sodium hypochlorite produced in an electrolyser (3) is fed back to a point in the brine feed upstream of the filter (2) such that any bromide in the brine is oxidized to bromine or hypobromous acid and therefore adsorbed by the filter (2).

    摘要: A method is disclosed for polishing geothermal brines containing iron-rich silica scale and silica particles suspended therein while removing and recovering copper, silver and other precious metals dissolved therein. The method comprises passing brine having a pH just below about 5.0 through a conduit packed with a metal higher in the electromotive series than silver for a time to sufficient for substantially all of the silver and other precious metals therein to precipitate onto the packing. Preferably, the packing comprises coiled zinc-galvanized steel chicken wire mesh packed in a sufficient density to act as a filter for said suspended particles. Dissolving the packing in a suitable acid will leave a precious metal-rich residue behind for subsequent recovery. When the brine is treated this process, the useful life of injection wells used to return cooled brine back to the geothrmal field is extended by at least about 3 times as compared to that observed with untreated brine.
