The report, the second of five volumes, describes water management for conventional combustion sources and assesses the current status of various studies and programs in water management and trends in water recycle/reuse. A coal-fired boiler produces both chemical and thermal pollution; the report focuses on the former. The many uses of water in a power plant and the varying requirements of water quality in those uses present major opportunities for water conservation and pollution control through wastewater management, equalization, and treatment of appropriate waste streams. Water management studies completed by EPA and industry can serve as models for new facilities. Treatment systems to maximize water reuse are being studied by the EPA, and improved evaporators appear promising.
