•Case Study: FGD Purge Treatment In Coal-Fired Power Generation

Stricter environmental policies and regulations worldwide are changing how industry approaches all aspects of business. Likewise, EU (European Union) environmental policies governing air, soil, and water quality have become progressively stringent. These policy changes affect the power industry's balance of meeting growing European energy demands with compliance to environmental standards.
The effective treatment of wastewater resulting from flue gas desulfurization (FGD) scrubbers in coal-fired power generation can vary depending on the type of coal, water sources, and environmental regulations.
Evaporation technology is an effective alternative to conventional treatment processes that allows for water reuse in addition to minimizing the overall wastewater volume up to zero liquid discharge (ZLD).
In order to conform with EU standards specific for flue gas, a coal-fired generation plant (at the time owned by Endesa, Italia, S.p.A.) in Monfalcone, Italy, undertook the measure of installing a state-of-the-art FGD (flue gas desulfurization) system at their facility. This system would remove SO2 (sulfur dioxide) from the emissions for the 336 MW coal-fired power station.
