This research focuses on four primary components of the Suspended Ion eXchangeRTM (SIXRTM) system. The first component was to evaluate the hydraulics of the SIX contactor. It was determined that no matter the flow regime and the paddle speed, the system had the same hydraulic patterns. The second component was to determine the best adsorption kinetics of the system. The best conditions that reached the optimum rate-constant was with a flow rate of 35m3/hr at a paddle speed of 50 Hz (G-value of 482s-1). The third component was to determine the best desorption rate of Dissolved Organic Carbon (DOC) in a lab-scale fixed-bed regeneration reactor. The optimum conditions that desorbed DOC from the resin was with the lowest flow rate at a long contact time of 32 minutes. The final component was to evaluate the SIXRTM technology with a different water matrix. It was determined that the SIXRTM technology was efficient on a bench-scale system but to evaluate it further, a pilot facility must be constructed if it's feasible.
