For situations where fly ash is collected separately (e.g. ahead of wet flue gas scrubbing systems), we offer two different methods for additional processing: Neutral scrubbing followed by solidification with added binders yields a material that can readily be landfilled. Acid ash scrubbing removes the heavy metals using acid flue gas scrubbing water, so that the residue can be recycled.		Ash silo
