Development of a Column Model to Predict Silica Breakthrough in a Mixed Bed Ion Exchanger
Abstract
A computer model was developed to predict silica breakthrough in an ion exchange column. Column material balance equations are derived using the assumptions of film diffusion control and bulk phase neutralization. The variations in outlet concentrations due to various model parameters were studied. Most of the literature on ion exchange modeling addressing the removal of silica is qualitative in nature. This study extends this qualitative background and makes a first attempt at quantitative silica ion exchange issues. The silica particulates are accounted for in the model.
