Comparison of Gypsum Dewatering Technologies at …

An important aspect of gypsum recovery is the solid-liquid separation technology that is used. This paper discusses three technologies that are used by coal-fired power plants to dewater and dry gypsum. These are centrifuges, continuous vacuum belt filters (CBF) and continuous-indexing vacuum belt filters (CI-BF) and rotary vacuum filters.

Investigation of Parameters Affecting Gypsum Dewatering …

However, quality issues such as an excessive moisture content, due to poor gypsum dewatering properties, may occur from time to time. In this work, the particle size distribution, morphology, and filtration rate of wet FGD gypsum formed in a pilot-scale experimental setup, operated in forced oxidation mode, have been studied.
