Special Issue Information

Dear Colleagues,

This Special Issue on ‘Membrane Separation Systems: Design and Applications’ aims to explore recent developments in membrane technology, particularly regarding the ways in which such technology can be practically applied to problems in chemical separation. Membrane separation technology is ubiquitous, with far-reaching industrial applications in (but not limited to) desalination, water purification, pharmaceuticals, food chemistry, recycling, the resources sector, and chemical analysis. As such, developments in membrane technology have the potential to improve the cost-effectiveness, sustainability, and efficiency of industrial processes at the global scale.

This Special Issue explores cutting-edge developments in the design of membrane separation systems to address a chemical separation problem or application. There are no restrictions on the type of membrane (i.e., reverse osmosis, ion-exchange, liquid membranes, etc.), and technology combining different membrane types is also within the scope of this Special Issue. This issue is open to researchers associated with membrane technologies in all fields, and covers a broad range of potential topics where the rational design of membranes for a given purpose is evident. Submissions may include (but are not limited to) laboratory-scale systems, industrial systems, membrane manufacturing, selectivity and separation efficiency studies, operating conditions and stability studies, and the evaluation or comparison of different extraction systems for a specific application.

We invite authors to submit original research articles, review papers, and short communications to this Special Issue.

Landfill leachate from some sites contains a high concentration of Mn2+, which may cause reverse osmosis (RO) membrane fouling during RO treatment. In this study, the effect of Mn2+ on RO membrane fouling caused by typical organic pollutants (humic acid (HA), protein (BSA), and sodium alginate (SA)) was systematically investigated, and it was found that Mn2+ exacerbates RO membrane fouling caused by HA, SA, and HBS (mixture of HA + BSA + SA). When the Mn2+ concentration was 0.5 mM and 0.05 mM separately, the membrane fouling caused by HA and SA began to become significant. On the other hand, with for HBS fouling only, the water flux decreased significantly by about 21.7% and further decreased with an increasing Mn2+ concentration. However, Mn2+ has no direct effect on BSA. The effect degrees to which Mn2+ affected RO membrane fouling can be expressed as follows: HBS > SA > HA > BSA. The density functional theory (DFT) calculations also gave the same results. In modeling the reaction of the complexation of Mn2+ with the carboxyl group in these four types of organic matter, BSA has the highest energy (−55.7 kJ/mol), which predicts that BSA binding to Mn2+ is the most unstable compared to other organic matter. The BSA carboxylate group also has the largest bond length (2.538–2.574 Å) with Mn2+ and the weakest interaction force, which provides a theoretical basis for controlling RO membrane fouling exacerbated by Mn2+.

Membrane fouling is a non-negligible issue affecting the performance of membrane systems. Particularly, organic fouling is the most persistent and severe form of fouling. The complexation between inorganic and organic matter may exacerbate membrane organic fouling. This mini review systematically analyzes the role of inorganic matter in membrane organic fouling. Inorganic substances, such as metal ions and silica, can interact with organic foulants like humic acids, polysaccharides, and proteins through ionic bonding, hydrogen bonding, coordination, and van der Waals interactions. These interactions facilitate the formation of larger aggregates that exacerbate fouling, especially for reverse osmosis membranes. Molecular simulations using molecular dynamics (MD) and density functional theory (DFT) provide valuable mechanistic insights complementing fouling experiments. Polysaccharide fouling is mainly governed by transparent exopolymer particle (TEP) formations induced by inorganic ion bridging. Inorganic coagulants like aluminum and iron salts mitigate fouling for ultrafiltration but not reverse osmosis membranes. This review summarizes the effects of critical inorganic constituents on fouling by major organic foulants, providing an important reference for membrane fouling modeling and fouling control strategies.
