Summary
Continuing studies at Brookhaven National Laboratory (BNL) have shown that cost-efficient biotechnology for the removal of toxic trace metals from geothermal sludge is feasible. Pilot-scale experiments have shown that fast rates (< 24-h) of metal removal at 55°C--60°C can be achieved with removal efficiencies of better than 80%, yielding a product well within the environmental regulatory limits. Recent studies have shown that radionuclides, such as radium present in low concentrations in some sludges, can also be removed by means of a secondary biotreatment. The process produces an aqueous phase which contains all of the regulatory metals in a soluble form. A follow-up technology for the treatment of the aqueous phase is concurrently being developed at BNL. Preliminary results indicate that a small volume concentrate of metals can be generated producing an aqueous phase which meets drinking water standards. In this paper the current state-of-the-biotechnology will be discussed.
