About the Book: Alternative Water Use for Power Plant Applications
A U.S. Department of Energy National Energy Technology Laboratory (DOE/NETL)
study estimated that in 2005, total U.S. freshwater withdrawals for
thermoelectric power generation amounted to approximately 146 billion gallons
per day (BGD), while freshwater consumption was 3.7 BGD. Coal-fired power plants
use water for cooling water systems, flue gas desulphurisation (FGD) makeup,
boiler makeup, ash handling, wastewater treatment, and general plant wash down.
As the population continues to increase, electric and water demands are expected
to grow. Thermoelectric power generation requires a large quantity of freshwater
to support operations. In regions of the country with limited
