These amendments initiated a new phase of installation of Flue Gas Desulfurization (FGD) scrubbers in the United States. The Clean Air Interstate Rules (CAIR), first filed by the EPA in 2004, required that more stringent requirements for SO2 and NOx emission control be met in phases by 2010 and 2015.
The Degremont Group, has been a leading provider of FGD wastewater treatment systems worldwide since the first installation of FGD scrubbers, which incorporated the production of saleable gypsum, were installed in Germany in the 1980’s. With over 35 installations worldwide, the Degremont Group has developed an extensive working knowledge of the operation of FGD wastewater treatment systems. Infilco Degremont (IDI), the US based subsidiary of the Degremont Group, has installed three FGD wastewater treatment systems in the US and is presently designing numerous more.
