This paper discusses the results of a project funded by the California Energy Commission Public Interest Energy Research (PIER) to complete an independent assessment of the energy savings, environmental improvements and water conservation capabilities of emerging non-chemical water treatment technologies. The project was completed by a team from California State University at Sacramento and included a technical review of the emerging technologies and a detailed assessment of the emerging non-chemical water treatment technology. Clearwater Systems, Corp. The research was focused on gathering information from industrial field customers who had purchased and installed these systems and had actual experience with their operational characteristics from several months to several years. The team completed a telephone survey with approximately 15 end user customers and made site visits to ten sites. Some limited independent water testing was also completed. The results of these phone surveys and site visits were consolidated and placed in an interim report. Even though only a small number of end user customers were actually surveyed or visited, the research indicated that several hundred systems have been successfully installed in California and throughout the United States. The emerging technologies provide nonchemical treatment for cooling tower and evaporative condenser system water. All the information collected and results derived from this effort will be made available to the public later this year in the form of a PIER Technical Report. A Project Advisory Committee that included representatives from CalEPA, the Energy Commission PIER Program and local utilities supported this team.
