Special Issue Information

Dear Colleagues,

Polymeric membranes are the dominating membrane type globally. They have been widely applied in various industrial fields such as water treatment, food and beverage, pharmaceuticals, and chemical industries. Polymeric membranes are commonly used for pressure-driven membrane processes microfiltration (MF), ultrafiltration (UF), nanofiltration (NF), and reverse osmosis (RO) due to their unique and tunable properties.

The focus of this Special Issue is to provide a platform for researchers and engineers to share their latest findings and advancements related to polymeric membranes. We welcome submissions on new membrane processes using polymeric membranes, innovative fabrication methods, new materials, and novel characterization techniques for polymeric membranes. With this Special Issue, we aim to contribute to the development of more efficient, cost-effective, and sustainable membrane processes for various industrial applications.

Sharing the latest research on polymeric membranes can support the development of important solutions to industrial problems such as water scarcity, energy consumption, and waste management. The new trends and advancements in polymeric membrane technologies presented in this Special Issue might lead to significant improvements in the performance and cost-effectiveness of industrial processes, as well as facilitate the achievement of the UN's SDGs.

Submissions of original research articles and reviews are welcome. We are looking forward to receiving your contributions.

Recent studies on membrane fouling have made considerable progress in reducing its adverse effects. However, a lack of comprehensive studies focusing on the underlying fouling mechanisms remains. This work aims to address a part of this gap by investigating the influence of feed suspension chemistry and operating conditions on the fouling characteristics of microcrystalline cellulose. Fluid dynamic gauging (FDG) was employed to monitor the properties of fouling layers under varied conditions. FDG results revealed that the cohesive strength of fouling layers increased in the direction towards the membrane, which can be associated with the higher compressive pressures exerted on foulants deposited near the surface. At lower pHs and higher ionic strengths, reduced electrostatic repulsions between particles likely resulted in particle agglomeration, leading to the formation of thicker cakes. In addition, thicker cake layers were also observed at higher feed concentrations, higher operating transmembrane pressures, and longer filtration times. The cross-flow velocity influenced the resilience of fouling layers significantly, resulting in thinner yet stronger cake layers in the transition and turbulent flow regimes. These findings regarding the influence of feed characteristics and operating conditions on the fouling behavior can be beneficial in developing effective antifouling strategies in membrane separation processes.
