Summary: Membrane filtration is a promising method for oily wastewater treatment, with ceramic membranes showing less fouling compared to polymeric membranes. Improving the fouling resistance of ceramic membranes is important for reducing energy consumption and increasing membrane lifespan. Different methods, including sol-gel, dip-coating, and atomic layer deposition, are used for ceramic membrane modification to enhance performance in oily wastewater treatment. Nano-sized metal oxides and graphene oxide are potential candidates for ceramic membrane modification to increase flux and alleviate fouling. Passive antifouling ceramic membranes, like photocatalytic and electrified ceramic membranes, have shown potential in fouling control, oil rejection, and flux enhancement, but also have limitations.

Summary: In this study, the mean pore size of MF membranes was optimized to maximize productivity and guarantee a high removal rate. The near DOM MF with an optimum mean pore size larger than but close to dissolved organic matter (DOM) was proposed for separating pathogenic protozoa. The results showed that an MF membrane with a 0.8 μm mean pore size had higher water fluxes and maintained a removal rate at 3-4 log compared to a 0.45 μm MF membrane.

Summary: Various sizes of microplastics (MPs) have been found in water bodies, with small MPs (<1μm) posing a threat to human health. Efforts have been made to remove MPs, but previous methods only achieved partial reductions. This study demonstrates that near dissolved organic matter microfiltration (NDOM MF) coupled with cold plasma (CP) treatment can efficiently remove MPs. CP treatment caused coagulation, increasing the particle size of MPs and enabling NDOM MF to achieve a higher water flux and maintain a high removal rate. The NDOM MF-CP process provides a sustainable and eco-friendly approach to removing MPs without secondary contamination.
