N2 - With a growing demand for the use of membrane technologies coupled with the growing demand for the use of magnetic ion exchange (MIEX) in water treatment, it is important to understand the implications of using MIEX as a pretreatment to membrane technologies. Anionic forms of MIEX (MIEX DOC) have been used in previous research to remove natural organic matter (NOM) and thus reduce fouling. However, there have been conflicting results. This research uses cationic MIEX (MIEX WA172) with varying mobile counter ions (Na+, Ca2+, and Mg2+) in four synthetic waters (with varying hardness ions) to probe the interactions of NOM and divalent cations. The goal of this research is to understand the implications of cation exchange with MIEX as a pretreatment to membrane technologies. 2010
