FGD WASTE WATER
Flue Gas Desulfurization (FGD) Waste water
Flue Gas Desulfurization (FGD) is a process that can require the use water to remove sulfur dioxide (SO2) from flue gases produced by burning high sulfur fuels such as coal and oil. Flue gas desulfurization, also referred to as Flue Gas Scrubbing (FGS), has been used since the 1960s in large stationary sources of pollution such as power plants.
The wastewater generated by Flue Gas Desulfurization is referred to as Flue Gas Desulfurization wastewater (FGD water) or Flue Gas Desulfurization 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, flourides, nitrates, nitrites and potentially harmful trace metals. This water must be treated prior to discharge. MINETEK has the ability to manage FGD wastewater through an innovative, yet simple water evaporation process and has a global network of specialists able to assist in any industrial setting around the world.
