In response to impending regulatory requirements and increased demand for high quality drinking water, the City of Geneva, Illinois, saw an opportunity to construct a new water softening facility that not only met these new requirements and provided softened water for the community, but also reflected the City's long-standing commitment to honoring and preserving its community heritage and character. A conceptual study was performed to identify the best water treatment process available for the City, concurrently with an evaluation to determine the most suitable location and architectural look for this new facility. In order to meet new limits for radionuclides in drinking water, promulgated in December 2000, as well as to provide softened water for the City, the conceptual study determined that the best method of treatment for Geneva would be membrane softening using nanofiltration (NF) or reverse osmosis (RO) membranes to remove dissolved constituents (such as calcium, magnesium, and radionuclides) from the water. The Illinois Environmental Protection Agency (IEPA) requires pilot testing of NF/RO membranes to demonstrate effective removal of radium. In addition to the IEPA requirement, because of elevated levels of iron and manganese in the shallow well water, it was determined that pilot testing should be conducted to determine design and operating parameters, long term fouling potential, and the extent of pretreatment necessary to protect the membranes. To that extent, a detailed pilot testing program was carried out to determine the design parameters for the full scale facility. The results of the pilot program and details of the full scale facility construction are presented in this paper. Includes tables, figures.
