Summary: Ceramic membranes made of fibers have high gas permeance and can be used for filtering dust-laden gases. A novel method of preparing a SiC fiber separation layer on a ceramic support was proposed to increase the porosity of the membrane. The interfacial adhesion between the support and separation layers was improved by vertically growing TiO2 nanocords on the support.

Summary: High-performance nanofiltration (NF) membranes were developed using hydrolyzed polyacrylonitrile (HPAN) ultrafiltration (UF) membranes as substrates, quaternized crosslinked microgels (PNI6) as intermediate layers, and piperazine (PIP) and trimesoyl chloride (TMC) for polyamide selective layer formation. The incorporation of positively charged PNI6 microgels enhanced the hydrophilicity and surface charge of the NF membranes. The resulting MG-NF membranes exhibited excellent water flux and rejection of salts. Increasing the deposition time of PNI6 microgels on the UF membranes improved water flux and MgCl2 rejection of the MG-NF series membranes. The thermo-responsive and long-term stable MG-NF-6 membrane showed a water flux of 10.1 L.m(-2).h(-1).bar(-1) and a MgCl2 rejection of 93.4% at 25 degrees C, which increased to 13.4 L.m(-2).h(-1).bar(-1) and 90% at 45 degrees C.

Summary: High-efficiency CO2 capture is crucial for mitigating the global temperature rise and its severe impacts on various aspects of human life. Thin-film composite membranes (TFCM) have gained attention due to their energy-efficient and environmentally friendly nature. However, the nonideal interface between the gutter layer and the separation layer limits the fabrication of defect-free and thin separation layers, resulting in poor separation performance. In this study, a strategy involving oxygen-plasma modification and spin-coating was developed to engineer the interface of TFCM and improve its performance.

Summary: Membrane filtration is a promising technology for efficient separation of water-in-oil (W/O) emulsions in petrochemical industries and oily wastewater treatment. However, commercial hydrophobic membranes face challenges of low selectivity, low permeance, and membrane fouling. In this study, a superhydrophobic PVDF membrane was developed through a facile and eco-friendly solute and solvent co-crystallization method, which successfully separated a wide range of (surfactant-stabilized) W/O emulsions. The membrane demonstrated excellent water droplets rejection, high oil permeance, high chemical stability, fouling resistance, and applicability under various pH and temperature conditions.

Summary: This study presents a new approach for efficient and selective dye recovery from highly saline textile waters using Co-MOF nanosheet membranes. The membranes exhibit superior permeance and selectivity due to their precisely regulated in-plane pore sizes. The Co-MOF membranes have high selectivity for salts over dye and exhibit excellent pure water permeance and high rejection of dyes. The in-plane pores on the nanosheets are responsible for the remarkable permeability and selectivity of the membranes.

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.
