Flue Gas Desulfurization (FGD)

What is flue gas desulfurization (FGD)?

Global regulation changes demand reduction of the emissions from power plants.
Flue gas desulfurization (FGD) is a set of technologies used to remove sulfur dioxide (SO2) from exhaust flue gases of fossil-fuel power plants, as well as from the emissions of other sulfur oxide emitting processes. When using a wet FGD scrubbing process, wastewater is generated, which must be treated before disposal
FGD wastewater contains high concentrations of sulfates, calcium, magnesium, heavy metals, TSS and ammonia.
Stricter regulations in Europe, China, USA and other countries require Zero Liquid Discharge (ZLD) treatment for the wastewater.
