摘要： Compositions for the treatment of flue gas desulfurization scrubber effluent may generally comprise, based on weight percent of the composition, at least 50% fly ash, up to 20% calcium oxide and/or calcium hydroxide, up to 2% plasticizer and a balance of incidental impurities. Methods for the treatment of flue gas desulfurization scrubber effluent using the composition for the treatment of flue gas desulfurization scrubber effluent are also described.
