This publication highlights proposed approaches and actual projects for dealing with such water quality issues at fossil power plants as water supply, water treatment, and the protection of surface water and ground water. Described are use of radial wells and a circulating water tunnel (CWT) as water sources for fossil power plants. Unique aspects of the CWT, for example, are a fish deterrent/fish return system, staged diffuser, and intake velocity cap. Solidification of a flue gas desulfurization slurry, a radically different method of handling and disposing of fly ash and bottom ash, a soil-bentonite cutoff wall for coal pile leachate control, conversion of a wet fly and bottom ash sluicing system to a dry fly ash handling system followed by landfilling, and other waste handling systems are included. In addition, development of a coal pile drainage model, data concerning the leachate characteristics of various fly ashes, and a methodology used to estimate waste quality discharge concentrations are presented. The handling, chemical and toxicological nature of wastewaters from combined cycle coal conversion facilities are also described. This volume is a compendium of state-of-the-art information that should be helpful to designers of treatment systems serving fossil power plants.
