Chemistry of FGD Blowdown
blowdown treatment is simpler than ZLD of flue gas desulfurization (FGD) blowdown water. This is because limestone‐based FGD systems produce waters with high concentrations of calcium and magnesium chloride, which require verymperatures high te to crystallize. Presently, ZLD is becoming a more viable
