Wet flue-gas desulfurization (FGD) process is a method for removing sulfur dioxide (SO2) from flue gas before it is released into the atmosphere from a power plant. Water-intensive flue gas scrubbing requires continuous treatment, FGD scrubber wastewater contains high concentrations of chloride ions (4,000–20,000 mg/L). It also contains high amounts of heavy metals such as chromium, mercury, and selenium, has a high concentration of nitrates (10–700 mg/L) and a very high TDS (20,000–60,000 mg/L).
