Flue-gas desulfurization (FGD) wastewater reclamation by integrated membrane process

Flue gas desulfurization (FGD) is a process implemented at coal-fired power plants to remove sulfur dioxide from exhausted flue gas. This process is typically done by using wet scrubbers producing huge amount of wastewaters. This work aims at evaluating the potential of an integrated membrane system based on the use of pre-treatment, reverse osmosis (RO) and membrane distillation (MD) to achieve water reclamation of FGD wastewaters and their reuse in FGD systems.
