Summary: Osmotic membrane bioreactors (OMBRs) are considered suitable for treating wastewater containing tetracycline, but the impact of membrane fouling layer on tetracycline filtration and its relationship with microbial activity is still unclear. This study investigated the effects of draw solute concentration and type on the formation of a membrane fouling layer for tetracycline filtration and found that the fouling layer played an important role in tetracycline filtration and degradation. The study provided insights into the combined effect of membrane fouling and microorganisms on tetracycline removal.

Summary: This study investigates the fouling properties of cake and bulk sludge in an anammox membrane bioreactor. The analysis reveals differences in the physical and chemical properties between the two sludges, such as denser structure and higher protein content in cake sludge. Moreover, the study finds that cake sludge has looser protein structures and more hydrophobic components, which play a key role in cake layer formation. Additionally, the relative abundance of certain microbial species in cake sludge suggests a higher biofouling potential. Overall, this research contributes to the understanding of membrane fouling control in anammox MBR.

Summary: In order to understand the interfacial behaviors controlling membrane fouling, a new method was proposed to simulate the actual membrane surface morphology and quantify interfacial interactions. This method precisely mimics the real membrane surface in terms of roughness and shape, achieving a precise description of the interactions between sludge foulants and the real membrane surface. Application of this method confirmed the significant antifouling propensity of the modified PVDF-NZPs membrane, which is highly consistent with experimental findings, suggesting the high feasibility and reliability of the proposed method.

Summary: The superficial air velocity (SAV) significantly influences the performance and membrane fouling of AGMBR. Experimental results showed that SAVs provided sufficient dissolved oxygen for efficient removal of organics and ammonium nitrogen. Higher SAV extended the lifespan of AGMBR, altered the content of foulants and microbial community structure. The cake layer with the highest porosity was observed at SAV of 2.6 cm/s, corresponding to the largest pore blocking fouling resistance and presence of fluorine on fouled membrane.

Summary: A novel membrane bioreactor (MBR) called ABGMBR was developed to improve pollutant removal and reduce membrane fouling. Compared to the control MBR (AGMBR), the ABGMBR system had higher pollutant removal rate and longer operation time. The ABGMBR system effectively reduced the content of pollutants on the membrane, resulting in the formation of a porous and loose cake layer and a slow increase in transmembrane pressure. The extended Derjaguin-Landau-Verwey-Overbeek theory suggested that the aggregation and adhesion of foulants on the membrane were greatly inhibited in ABGMBR.

Summary: Wastewater treatment plants play a crucial role in capturing microplastics before they enter natural waterways. However, the study reveals that sub-micron microplastics and nanoplastics have been neglected due to limitations in current analytical methods. The research investigates the impact of short poly(ethylene terephthalate) (PET) nanofibers on the performance of polyvinylidene fluoride (PVDF) ultrafiltration membranes. The results show that PET fibers attach to the membrane in a disorganized manner, reducing the water flux by 8% in pure water but no noticeable effect in wastewater.

Summary: Microbial quorum quenching (QQ) is an effective approach to mitigate biofouling in MBRs by reducing biopolymers production and improving sludge conditions. This study investigated the impact of aeration rate on the performance, membrane fouling, and energy consumption of QQ-MBR and C-MBR. It was found that QQ significantly mitigates biofouling, but the efficiency is lowest at high aeration intensity. QQ also reduces the content of SMP and EPS in sludge, with better performance at moderate aeration intensity. High aeration intensity results in the highest energy consumption, while QQ can optimize energy consumption by minimizing aeration intensity.

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: A low-cost approach using in-situ reduction strategy was developed to prepare PDA@NixCo100-x nanotubes, which contained active NiCo nanoparticles encapsulated in the inner wall. The optimized PDA@Ni25Co75 nanotubes exhibited excellent photocatalytic performance, achieving 99.3% degradation of methyl orange and 95.7% degradation of 4-nitro phenol in 10 and 15 minutes, respectively, outperforming previous materials reported in literature. The self-sustained high-density PDA@Ni100Co0 nanotube arrays obtained by removing the membrane structure were efficient catalysts for pollutant capture. This cost-effective nanocatalyst approach has great potential for large-scale applications in environmental remediation, demonstrating significant innovation and contribution to the field.

Summary: The surface chemistry and functionality of metal-organic frameworks (MOFs) can be controlled by integrating them with carbon quantum dots (CQDs). In this study, UiO-66-NH2/CQD heterojunctions were prepared and used as nanofillers in thin-film nanocomposite (TFN) membranes for dye removal. The loaded CQDs enhanced the compatibility of UiO-66-NH2 with the polyamide matrix and promoted photocatalytic oxidation under visible light. The TFN membranes embedded with 0.2 wt% UiO-66-NH2/CQD showed significant improvements in water permeance and selectivity to different dyes. The attached dyes could be efficiently degraded within 10 minutes through photocatalytic degradation. This work provides a new strategy for fabricating defect-free and self-cleaning nanofiltration membranes for dye removal and wastewater reclamation.
