12-02: A Synergistic Combination of Advanced Separation and Chemical Scale

Water is essential to thermoelectric power plants, used primarily for cooling. Using impaired water in place of freshwater is a potentially attractive solution to the problems of water scarcity and competing demands.  Nalco was awarded DOE grant to develop a cost-effective integrated solution (chemical and physical) for the use of impaired water and maximize the cycles of concentration.  Argon National Laboratories under CRADA demonstrated the use of ED/RWEDI while Nalco developed scale inhibitors for the integrated solution
