However, if not possible, one potential treatment strategy is bringing the pH of the waste low, then adding an iron salt to try to get the gluconate to mostly tie up iron rather than copper, then raising the pH with lime. This strategy is sometimes called "chelate breaking" in the wastewater treatment industry. Regards, Ted Mooney, P.E.
