The objective of this research was to evaluate a magnetic ion exchange resin for the removal of natural organic material and bromide on a continuous-flow pilot-scale basis under different operating conditions and raw water characteristics. The most important operating variable was the effective resin dose (ERD), which is the product of the steadystate resin concentration in the contactor and the regeneration ratio. The raw water employed in this study had a moderate concentration of ultraviolet (UV)-absorbing substances and dissolved organic carbon (DOC), and a low turbidity, alkalinity, and concentration of anionic species. Experiments were conducted using the ambient raw water and raw water spiked with bromide, chloride, and sulfate. Increasing the ERD resulted in increased removal of UV-absorbing substances and DOC. Moderate bromide removal was achieved, depending on the ERD. Increasing the sulfate concentration resulted in decreased removal of UV-absorbing substances, DOC, and bromide.
