An evaporation/solidification technology for flue gas desulfurization (FGD) meets U.S. Environmental Protection Agency (EPA) guidelines governing wastewater discharge from steam electric and coal-fired power plants.

GE’s technology reduces chemical addition, sludge handling and energy costs. It also reduces the long-term environmental risks associated with the discharge of FGD purge water and other liquid streams from power plants and produces high-quality water for recycle and reuse.

This technology is beneficial to power plants because it can treat FGD wastewater from any type of coal and removes the risk of meeting discharge requirements by eliminating liquid discharge to waterways.
