ANDRITZ Guide for FGD Gypsum Dewatering

ANDRITZ Guide for FGD Gypsum Dewatering

FGD Process Gypsum Dewatering Gypsum slurry mostly dewatered by a two-stage process 1. Slurry is pre-thickened and partly classified by a set of hydro-cyclones in first step. Though not very common, static thickeners can be used alternatively. 2. Further dewatering and cake washing in second step. - water content of commercial grade gypsum needs to be below 10 wt.

Involvement of Gypsum CaSO4 183 2H2O in Water Treatment

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 significantly, gypsum serves as a skeleton builder, forming a ...
