Abstract

P arametric tests were conducted to determine kinetic rate equations needed to support design of a water treatment system employing commercially available ion-exchange resin (IXR), but operating in a kinetic process regime. (Editorﾒs note: In the text, the acronym IX refers to the ion exchange process itself.) Initial loading of IXR in dilute, well-mixed, suspensions exhibits pseudo first order reaction kinetics, where the IX rate is proportional to the square root of the product of the ion concentration in solution and the concentration of available exchange sites on the resins. The relative rate of removal of two ionic species in the kinetic regime is proportional to the ratio of their concentrations in solution raised to the 1.5 power.
