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. In order to conform with EU standards specific for flue gas, a coalfired 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.
Design-Build Using Actiflo Technology
A state-of-the-art 695-MW power generation facility was recently installed in the Northeastern U.S. to serve the country’s highest demand market. Its innovative power generation technologies, emissions control systems and process efficiencies make it one of the cleanest, most efficient and technologically advanced supercritical pulverized coal (SPC) power plants in the U.S.

The New Harquahala Generating Project serves as a power and electrical wholesaler in the Southwestern United States. To fill the need for growing energy consumption in the region, this facility was built to provide power to the area.
Maximum Water Reuse, Zero Liquid Discharge — A Power Plant Case Study
ELCOGAS, established in 1992 with the aim of building and operating a 335 MW Integrated Gasification Combined Cycle (IGCC) power plant as well as the commercialization of its technology.
The Otay River Pump Station (ORPS) was upgraded in 2003, to feed effluent to the City of San Diego’s newly constructed South Bay Water Reclamation Plant. By Glenn Dorsch, P.E, VP/Chief Engineer, Vaughan Co. Inc.

ABOUT WASTEWATER DISINFECTION
Wastewater disinfection takes place after primary, secondary and sometimes tertiary wastewater treatment. It is typically a final step to remove organisms from the treated water before the effluent is released back into the water system. Disinfection prevents the spread of waterborne diseases by reducing microbes and bacterial numbers to a regulated level.
A variety of physical and chemical methods are used to disinfect wastewater prior to it being released into natural waterways. Historically, the chemical agent of choice for municipal wastewater treatment has been chlorine, due to its disinfecting properties and low cost. However, the rising cost of chlorine and concerns that low chlorine concentrations can still be toxic to fish and other wildlife, has given rise to more physical methods of wastewater disinfection being adopted such as ozonation or ultraviolet (UV) light.
The use of ozone as a disinfection agent has the added benefit of increasing the dissolved oxygen content of the treated wastewater. However, because the ozone has to be generated, ozonation can require prohibitive up-front capital expenditure compared to traditional chlorination. UV disinfection has been growing in popularity as a wastewater disinfection method, in large part because of the life-cycle economics of the equipment and the fact that, like ozone, there is no toxic residual.
