A Synergistic Combination of Advanced Separation and Chemical Scale Inhibitor Technologies for Efficient Use of Impaired Water in Cooling Towers

摘要

Water is essential to thermoelectric power plants, used primarily for cooling. Using impaired water in place of fresh water 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.
