When the Village of Plover, Wisconsin, set out to develop additional water supplies, extensive previous studies established that treatment for nitrate removal would be required to comply with drinking water regulations because of widespread aquifer contamination. As part of the planning process, alternative nitrate removal technologies were examined, and anion exchange was selected for the permanent plant. The Village had previously installed an ISEP continuous regeneration anion exchange system, but after a thorough examination of capital and operating issues, selected a more conventional fixed bed process for the new facility. This provides a unique opportunity for side-by-side comparisons of the alternative ion exchange technologies (IE) in terms of technical issues and requirements, performance, operation, and maintenance. This paper presents the critical aspects of the decision-making process, and experience information that will be extremely useful for other communities who may be faced with similar treatment challenges. Includes tables, figures.
