Flue Gas Desulfurization (FGD) is a process that can require the use of water to remove sulfur dioxide (SO2) from flue gases produced by burning high sulfur fuels such as coal and oil. Also referred to as Flue Gas Scrubbing (FGS), FGD has been used since the 1960s in large stationary sources of pollution such as power generation plants.
The wastewater generated by Flue Gas Desulfurization is referred to as FGD wastewater (FGD water) or FGD bottom ash with wet scrubbers used to scrub the water of gases.
The result, however, is water high in contaminants and pollutants. The wastewater is often supersaturated with gypsum and is highly acidic with high concentrations of Total Dissolvable Solids (TDS) and Total Suspended Solids (TSS) with chlorides, fluorides, nitrates, nitrites and potentially harmful trace metals.
This water that comes from FGD must go through proper wastewater removal systems prior to discharge. MINETEK has the ability to manage FGD wastewater through an innovative, yet simple, and sustainable groundwater management and water evaporation processing with a global network of specialists able to assist in any industrial setting around the world.
