Select the materials used that come into contact with the wet FGD slurry and effluent. High ORP slurries can contain ionic manganese, which is corrosive. The systems to be considered include the absorber re-circulation tank, pumps, dewatering equipment, vacuum systems for gypsum production, piping and waste water treatment equipment. Constituents of the wet FGD slurry will include limestone, gypsum, halide ions, and metals as well as silica from the ash and other upstream constituents.
