Heavy metal removal from power generation waste streams and coal ash by Calcium Polysulfide Solution.

REMOTOX® is used to capture and stabilize mercury, lead, copper, thallium, cadmium, nickel, zinc, silver and other metals commonly found in power plant waste and scrubber wastewater. The product forms large polysulfide particles for easy removal in absorber solids and usually passes TCLP/STLC tests for more environmentally sound recycling or disposal.


REMOTOX® has also been tested and evaluated for hydrodechlorination/detoxification of polychlorinated compounds in fly ash. See abstract on Hydrodechlorination/detoxification of PCDDs, PCDFs, and co-PCBs in fly ash by using calcium polysulfide.


With regard to product's application for the successful removal of mercury from flue gasses, we would be happy to refer you to the experts in this field, who offer proprietary calcium polysulfide technologies and consulting services to help you achieve your site-specific environmental targets the most practical and cost-effective way.
