[PDF] Involvement of Gypsum (CaSO4
Abstract This research assessed the use of gypsum (CaSO4 · 2H2O) as a skeleton builder for sludge dewatering since polymer conditioning of sludge affected only the rate of water release, not the extent of dewatering. The use of gypsum as a physical conditioner, in association with a polymer, could improve sludge filterability. More …

Gypsum – a scarce raw material?
The gypsum landfill there, Jänschwalde II, has been run since 2011 in two-shift operation for the FGD gypsum from LEAG's Jänschwalde 6 x 500 MW lignite-fired power plant. The delivered gypsum is placed in the landfill by means of a rail-mounted spreader (Fig. 11) and reclaimed with a wheel-loader (Fig. 12).

FGD Gypsum Production Process
Mineralogically identical to natural gypsum, FGD gypsum, or synthetic gypsum, is produced from gas captured within emission control systems at coal fired electric utilities. An emission that would compromise air quality, sulfur dioxide (SO2) gas, is the primary contribution coal makes to FGD gypsum. Utilities that produce panel-grade synthetic …
