While reverse osmosis (RO) is the leading technology to address global challenge of water scarcity through desalination and potable reuse wastewater, current RO membranes fall short in rejecting certain harmful constituents from seawater (e.g., boron) wastewater [e.g., N-nitrosodimethylamine (NDMA)]. In this study, we develop an ultraselective polyamide (PA) membrane by enhancing interfacial polymerization with amphiphilic metal-organic framework (MOF) nanoflakes. These MOF nanoflakes...
Extracellular polymeric substances (EPS) are key foulants in membrane bioreactors (MBRs). However, their positive functions of protecting microorganisms from environmental stresses, e.g., during situ hypochlorite chemical cleaning membranes, have not been adequately elucidated. In this work, we investigated the response an MBR to various dosages NaOCl, with a particular emphasis on mechanistic roles EPS. Results showed that functional groups EPS such as hydroxyl and amino were attacked by...
Abstract Membrane fouling remains an obstacle to wide-spread applications of membrane bioreactors (MBRs) for wastewater treatment and reclamation. Herein, we report a simple method prepare composite conductive microfiltration (MF) by introducing stainless steel mesh into polymeric MF effectively control its applying external electric field. Linear sweep voltammetry electrochemical impedance spectroscopy analyses showed that this had very good properties. Batch tests demonstrated anti-fouling...
Widespread applications of membrane technology call for the development antibiofouling membranes. For traditional contact-killing strategy, antibacterial action is restricted to surface: loses its efficacy once surface completely covered with a fouling layer. However, in this study, polyvinylidene fluoride (PVDF) microfiltration membranes blended quaternary ammonium compound (QAC) exhibited surprisingly lasting antimicrobial activity vicinity surface. The results indicated that QAC was...
Widespread applications of reverse osmosis (RO)-based processes call for high-performance thin-film composite (TFC) membranes. In this study, a TFC membrane by incorporating an ultrathin 2D metal–organic framework (MOF) (ZnTCPP) interlayer was developed water purification, and the mechanisms in enhancing permeability selectivity were revealed. The introduction MOF nanosheet nearly tripled permeance (4.82 ± 0.55 L m–2 h–1 bar–1) with simultaneous increase NaCl rejection (97.4 0.6%) compared...
Metal-phenol coordination is a widely used method to prepare nanofiltration membrane. However, the facile, controllable and scaled fabrication remains great challenge. Herein, novel strategy was developed fabricate loose membrane via integrating blending interfacial strategy. Specifically, iron acetylacetonate firstly blended in Polyether sulfone (PES) substrate non-solvent induced phase separation (NIPS), then selective layer formed on surface with tannic acid (TA) crosslinking reaction...
Two bioelectrochemical membrane bioreactors (MBRs) developed by integrating microbial fuel cell and MBR technology were operated under closed-circuit open-circuit modes, high-throughput 454 pyrosequencing was used to investigate the effects of power generation on community bio-anode bio-cathode. Microbes anode operation (AO) enriched highly diverse when compared those (AC). However, among cathodes mode (CC) had richer more cathode (CO). On anodes AO AC, Proteobacteria Bacteroidetes dominant...
