wastewater discharge limits likely to be enforced for the FGD wastewater • The quantity of additional sludge generated by treatment of the FGD wastewater may exceed the sludge and solids handling capacity of the existing system The specific FGD wastewater treatment system must be designed to ,

Flue Gas Desulfurization Wastewater Treatment PrimerKnow More

Therefore, FGD wastewater may contain as much as 7% suspended solids (if primary hydroclone overflow is used) or as little as 30 ppm of suspended solids (when using thickener or stacking pond .

Benefits of evaporating FGD purge waterKnow More

FGD is an evaporative process, so it concentrates these impuriti The wastewater from gypsum dewatering will have a pollutant content that depends mostly on the type of coal burned, the .

The FGD wastewater can contain TDS in excess of 31,000 parts per million (ppm), total hardness of 30,000 ppm, chlorides of 20,000 ppm, and total suspended solids (TSS) of 10,000 ppm The blowdown wastewater is purged from the system whenever the chloride concentration in the water exceeds 20,000 ppm of chlorid


conducted to continuously treat 1-2 gpm of the FGD wastewater for five months at Plant Wansley, a coal-fired power plant of Georgia Power This demonstrated that the scaled-up system was capable of reducing the total selenium (of which most was selenate) in the FGD wastewater from over 2500 ppb to below 10 ppb and total mercury from over
