مستخلص: Organic matter has been identified as a significant type of foulant in membrane processes for water treatment. Its fouling tendency is highly affected by the presence of ions and inorganics. While the effects of ions addition on organic fouling have been extensively researched in the past, studies on the effect of positively-charged inorganics, such as Fe 2+ and Mg 2+ , on organic fouling are limited. This study investigates the influence of Fe 2+ and Mg 2+ addition on fouling properties of the Suwannee River Organic Matter (SROM) solution in the MF process, with and without Ca 2+ ions. Results showed that increasing the concentration of Fe 2+ and Mg 2+ from 0-5 mM promoted SROM fouling, and resulted in an increased flux decline up to 33% and 58%, respectively. Cake layer resistance became more dominant with the addition of Fe 2+ and Mg 2+ , and was counted for more than 60% of the fouling. Mg 2+ , however, caused higher internal pore blocking, and facilitated the formation of a less permeable cake layer, compared to Fe 2+ . This was evident in the analysis of the cake layer properties and the visualization of the fouling layer. In all cases, SROM fouling with Fe 2+ and Mg 2+ worsened with the addition of Ca 2+ ions. The results of the study indicated the importance of understanding the interaction between organic matter and Fe 2+ and Mg 2+ , which would provide useful insights on their fouling mechanism and control.
