Special Issue Information

Dear Colleagues,

With increasing water demand and deteriorating water environments, the scarcity of freshwater sources and deterioration of water environments have jointly made the water crisis a salient global concern. Water and wastewater treatment can not only mitigate water pollution but can also relieve water shortage through the production of high-quality freshwater. Membrane-based technologies have been widely used for water/wastewater treatment and reclamation owing to there being no need for chemical addition as well as relatively low energy consumption and high automation capability. However, irreversible membrane fouling encumbers the performance and efficiency of membrane systems. Insights into the membrane fouling mechanism and strategies for membrane fouling control are of great importance. This Special Issue aims to deepen the understanding of membrane fouling phenomena and mechanisms and propose feasible membrane fouling control strategies during water/wastewater treatment.

For this Special Issue, original research articles and reviews are welcome. Research areas may include (but are not limited to) the following:

  • Membrane fouling characterization;
  • Modeling and simulation;
  • Membrane fouling control;
  • Membrane material;
  • Membrane module design;
  • Pressure-driven membrane technology;
  • Electronic membrane technology.

We look forward to receiving your contributions.

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 Fe2+ and Mg2+, on organic fouling are limited. This study investigates the influence of Fe2+ and Mg2+ addition on fouling properties of the Suwannee River Organic Matter (SROM) solution in the MF process, with and without Ca2+ ions. Results showed that increasing the concentration of Fe2+ and Mg2+ 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 Fe2+ and Mg2+, and was counted for more than 60% of the fouling. Mg2+, however, caused higher internal pore blocking, and facilitated the formation of a less permeable cake layer, compared to Fe2+. This was evident in the analysis of the cake layer properties and the visualization of the fouling layer. In all cases, SROM fouling with Fe2+ and Mg2+ worsened with the addition of Ca2+ ions. The results of the study indicated the importance of understanding the interaction between organic matter and Fe2+ and Mg2+, which would provide useful insights on their fouling mechanism and control.
