Data from bench-scale tests were used in conjunction with computer model simulations to develop design criteria for an ion exchange treatment process for removing nitrate. This approach is a potentially economical means of predicting nitrate breakthrough profiles, which can be used to make preliminary assessments of nitrate operating capacity, as well as the effects of changing process parameters, on the operational efficiency of various ion exchange processes. In addition, the effects of volatile organic chemicals, strong oxidants such as chlorine, and arsenic adsorption on ion exchange resin degradation were assessed.
