Summary: Zwitterionic surface engineering was employed to improve the antifouling ability of hollow-fiber membranes. A flow-through coating method using zwitterionic organosilica material was used to introduce zwitterions onto the membrane, which was then incorporated into a membrane bioreactor (MBR) to demonstrate enhanced fouling control. The zwitterion-coated membrane showed superior fouling resistance in the MBR, with improved critical flux, extended fouling cycle, and higher resistance to key foulants such as extracellular polymeric substances (EPS) and soluble microbial polymer (SMP). The interfacial free energy analysis revealed that zwitterions altered the interfacial interaction between the membrane and the fouling substances, leading to elevated energy barrier for foulants attachment.

Summary: Ceramic membranes can effectively alleviate membrane fouling in drinking water treatment with the use of intensive membrane cleaning techniques. Granular scouring combined with pre-treatment is effective in reducing fouling, and chemical membrane cleaning using oxalic acid followed by NaClO is highly efficient for irreversible fouling. Analysis of the foulants extracted from the fouled ceramic membranes suggests the presence of humics and biopolymers, indicating the need for new analytical methods to distinguish between them.

Summary: Complex geometries for electrodes pose a challenge in electrochemical applications. Slurry electrodes utilize complex flow distributors to enhance charge transfer between the current collector and slurry particles. In this study, titanium-based flow distributors produced by indirect 3D-printing were used to further improve electron transfer in vanadium redox flow applications. The titanium static mixers were coated with graphite to enhance activity for vanadium redox reactions. Heat treatment of the electrodes significantly improved anodic and cathodic current peaks, and testing in a redox flow cell showed discharge polarization of 110 mA cm(-2).

Summary: This paper presents an analysis of the fouling of a ceramic membrane by a mixture containing high concentrations of humic acid and colloidal silica during cross-flow ultrafiltration under various operating conditions. The experiments showed that colloidal silica exacerbates fouling and results in lower fluxes compared to the humic acid feed water. However, under certain conditions, lower concentrations of humic acid can lead to reduced fouling and higher fluxes.

Summary: This study systematically investigated the fouling and backwashing of anionic polystyrene particles in microfluidic structures with engineered surface charge and hydrophilicity. The results confirmed that increasing the hydrophilicity of the membrane can reduce fouling, but hydrophilicity alone is not a sufficient measure to predict particle deposition and removal behavior. Designing a hydrophilic membrane with an engineered surface charge is crucial for achieving a low-fouling membrane that can be cleaned effectively during backwashing with pure flow reversal.

Summary: In this study, the operational range of electro-driven processes was extended through reducing diffusion resistances and electroconvective mixing. A new membrane cell design and a high-speed microparticle tracking velocimetry setup were used to observe and quantify the 3D velocity field in a spacer-filled electrodialysis channel. The results showed the interplay between spacer-engineered hydrodynamics and electroconvection, and suggested that intentional regions of low flow velocity in the spacer design can maximize the use of electroconvection in the far overlimiting region.

Summary: Vasculogenesis and angiogenesis can be mimicked in vitro to maximize vascularization in 3D cell cultures through the orchestrated secretion of multiple growth factors. The study investigates the temporal influence, concentrations, and combinations of growth factors on in vitro vascularization inside hydrogels. It demonstrates that combinations of angiopoietin-1, angiopoietin-2, and PDGF-BB have the most significant effect on vascularization, and MSCs are the best supporting cells for the coculture. Furthermore, the study reveals that blood vessels align with magnetically oriented microgels and that transforming growth factor-beta can induce fibrosis and affect vessel formation.

Summary: The modification of membranes using the Layer-by-Layer (LBL) method with polyelectrolytes has become advanced technology, but it is time consuming. This study explores a simpler one-step membrane modification using coating solutions containing both polyanions and polycations. Different coating methods are proposed: interfacial complexation (IC), diffusive desalination (DDS), and polyelectrolyte concentration (PC). The ability to produce nanofiltration membranes and in-situ functionalization of the membranes are evaluated. With PC, membranes with high MgCl 2 rejection and permeability are obtained.

However, it is difficult to incorporate these techniques with spiral wound modules (SWMs) widely used in water and wastewater treatment. This study developed a prototype membrane system to accommodate angular vibrations with a modified SWM, and experimental results showed that applying angular vibrations can effectively control algal fouling in an SWM with lower energy consumption compared to traditional methods.
