Abstract ：
The increasing reliance on lithium-ion batteries (LIBs) intensifies the demand for efficient treatment of metalcontaining wastewater produced from the disposal of spent LIBs. Despite the widespread use of reverse osmosis (RO) for this purpose, conventional polyamide (PA) membranes often suffer from low water flux and high fouling susceptibility, undermining their treatment efficiency. Here we developed novel RO membranes, namely PA-M1, PA-M2, PA-M3, and PA-M4, from a traditional PA membrane (PA-M0) through a solventregulation and metal-coordination strategy. The novel membranes possess favorable structural and physicochemical properties, enabling more effective treatment of Li+/Co2+ wastewater from spent LIBs recycling. Notably, PA-M4 features a porous internal structure and a positively-charged surface, producing a water flux of 6.3 LMH/bar when treating 1000 ppm Li+/Co2+ wastewater, representing a 142.3 % increase over that of PA-M0 (2.6 LMH/bar) while maintaining Li+ retention above 94.0 %, comparable to the best-reported values. Particularly, PA-M4 sustains a flux above 5.5 LMH/bar after three 12-h testing cycles in the presence of organophosphorus foulants, 3.8 times higher than PA-M0 (1.4 LMH/bar). These results underscore the exceptional efficiency and superior anti-fouling properties of PA-M4, offers a practical protocol for designing highperformance RO membranes for treating metal-containing wastewater from spent LIBs recycling.

Abstract ：
Membrane fouling is a significant challenge in membrane-based water treatment processes, significantly impairing water recovery efficiency and reducing membrane lifespan. Electrochemically assisted membrane cleaning (EAMC), which employs electrons as the reaction medium, has demonstrated effectiveness in removing various membrane foulants, thereby mitigating fouling. As an emerging technique free of solvents and chemicals, EAMC has received considerable research attention, with a large number of studies published in recent years. However, reviews in this field remain scarce, underscoring the need for an updated study to guide future research. This article offers a critical review of the recent advancements in EAMC. It begins with an exploration of the mechanisms of membrane fouling induced by different contaminants, followed by a thorough examination of the operational principles and factors of EAMC. The review then delves into the fouling removal mechanisms and the practical applications of EAMC, evaluates the strengths and limitations of this innovative approach, and concludes with a discussion of the challenges and potential future directions in EAMC research. This work provides valuable insights into the development and application of EAMC technology.

Abstract ：
Purifying water contaminated with emulsified oil via forward osmosis (FO) is still plagued by low water recovery efficiency and poor fouling resistance of membrane. Herein we design a series of arginine-copper complexes to construct antifouling FO membranes from a polyamide membrane (PA-M) for oily water reclamation. A modification layer abundant in Cu2+ and guanidino is formed on the PA selective surface. It endows the membranes with desired structural and physicochemical properties that benefit the FO separation. The membrane functionalized with copper arginine sulfate (CAS-M) outperforms PA-M with water fluxes enhanced by 151 % against DI water. CAS-M also achieves higher oil-water separation efficiency with the water recovery rate increased by 94 % compared to that of PA-M when 3000 ppm emulsified oil as the feed. Remarkably, CAS-M exhibits excellent antifouling and antibacterial performance with a 98 % antibacterial rate and easier cleaning property after being fouled. Favorable physicochemical and structural characteristics as well as advantageous water transfer properties are the major benefits of CAS-M. This makes CAS-M outperform PA-M and other recently reported FO membranes with exceptional water permeability and antifouling ability. This study demonstrates an eco-friendly protocol to develop antifouling and antibacterial FO membrane for sustainable oily water purification.

Abstract ：
The demand to recover value-added resource is intensified due to the accelerating growth of resource waste with wastewater discharge. Here we design pH-responsive sodium salts of an imidazole-based ionic solid (im-IS), imIS-Na and im-IS-2Na, as draw solutes for forward osmosis (FO) to achieve resource recovery. im-IS-Na and im-IS2Na both have an expanded structure and contain multiple ionic moieties. These attributes make them generate a sufficient driving force for FO separation and negligible solute losses. Consequently, im-IS-Na and im-IS-2Na at 1.0 M produce pure water fluxes of 27.5 LMH and 32.0 LMH, respectively, increased up to 128 % relative to those of conventional draw solutes. im-IS-Na can concentrate the glycine-containing solution efficiently with a water flux of 17.6 LMH, 183 % and 25 % higher than those of NaCl and NH4HCO3, 4 HCO 3 , separately. Particularly, im-IS-Na preserves the glycine product intact, whereas NaCl and NH4HCO3 4 HCO 3 either denature or contaminate it resulting from their severe reverse diffusion. im-IS-Na and im-IS-2Na are conveniently regenerated by pH regulation involving no organic solvent and external pressure which are commonly used in recycling other draw solutes. imIS-Na and im-IS-2Na thus demonstrate their superiority as FO draw solutes to recover value-added resources.

Abstract ：
A large amount of organophosphorus-containing wastewater is produced in spent lithium-ion battery disposal. Forward osmosis (FO) offers unique advantages in purifying this kind of wastewater if suitable draw solutes - the core of FO technology, are available. Herein we synthesize several pH-sensitive zinc complexes, namely ZnATMP-iNa (i = 0, 1, 2, 3, 4), from ZnSO4 and amino tris(methylene phosphonic acid) (ATMP) obtained from scale inhibitor wastes for organophosphorus-containing wastewater remediation. Among these ZnATMP-iNa, ZnATMP-3Na best meets the standards of an ideal draw solute. This makes ZnATMP-3Na outperform other reported draw solutes. 0.6 M ZnATMP-3Na produces a water flux of 12.7 LMH, 136 % higher than that of NaCl and a solute loss of 0.015 g/L, lower than that of NH4HCO3 (0.83 g/L). In organophosphorus-containing wastewater treatment, ZnATMP-3Na has higher water recovery efficiency (8.3 LMH) and sustainability than NaCl and NH4HCO3, and is sufficient to handle large quantities of wastewater. Remarkably, the pH-responsive property allows ZnATMP-3Na to be readily recovered through pH-control and reused in FO. The ionic property, expanded cage-like structure and easy-recycling make ZnATMP-3Na achieve sustainable FO separation and superior to other draw solutes. This study provides inspiration for draw solute design from wastes and extends FO application to organophosphorus-containing wastewater remediation.

Abstract ：
The demand to effectively treat medical wastewater has escalated with the much greater use of antiviral drugs since the COVID-19 pandemic. Forward osmosis (FO) has great potential in wastewater treatment only when appropriate draw solutes are available. Here, we synthesize a series of smart organic-inorganic polyoxomolybdates (POMs), namely, (NH4)6[Mo7O24], (PrNH3)6[Mo7O24], (iPrNH3)6[Mo7O24], and (BuNH3)6[Mo7O24], for FO to treat antiviral-drug wastewater. Influential factors of separation performance have been systematically studied by tailoring the structure, organic characteristics, and cation chain length of POMs. POMs at 0.4 M produce water fluxes ranging from 14.0 to 16.4 LMH with negligible solute losses, at least 116% higher than those of NaCl, NH4HCO3, and other draw solutes. (NH4)6[Mo7O24] creates a water flux of 11.2 LMH, increased by more than 200% compared to that of NaCl and NH4HCO3 in long-term antiviral-drug wastewater reclamation. Remarkably, the drugs treated with NH4HCO3 and NaCl are either contaminated or denatured, while those with (NH4)6[Mo7O24] remain intact. Moreover, these POMs are recovered by sunlight-assisted acidification owing to their light and pH dual sensitivity and reusability for FO. POMs prove their suitability as draw solutes and demonstrate their superiority over the commonly studied draw solutes in wastewater treatment.

Abstract ：
The demand to improve the chlorine resistance of polyamide (PA) membranes is escalated with greater amounts of chlorine-containing disinfectant being used in global water treatment during the COVID-19 pandemic. In this work, we designed thiophene-functionalized poly(ethyleneimine) (TPEI) materials first and grafted them onto a conventional PA membrane to develop novel nanofiltration membranes (PEI-M, TPEI-1-M, TPEI-2-M). These membranes have dual-functionalized selective surfaces covered by hydrophilic amino groups and electron-rich thiophene moieties, which endow these membranes with superior chlorine resistance and improved separation performance. The modified membranes increase the rejection of MgCl2 from 86.5% of the nascent PA membrane (PA-M) to higher than 93.0% without sacrificing the membrane water permeability. More stable separation performance is achieved with all of the as-prepared membranes than PA-M after exposure to a 2000 ppm sodium hypochlorite solution. TPEI-2-M outperforms other membranes after being treated in a chlorination intensity of 16,000 ppm center dot h with the smallest flux loss and the highest MgCl2 rejection. This is mainly ascribed to the highest amount of amino and thiophene moieties on the TPEI-2-M surface. This study provides an effective protocol for developing novel PA-based nanofiltration membranes while demonstrating its superiority over current technologies with exceptional separation performance and antichlorine ability.

Abstract ：
The demand to remove Co2+ ions from industrial wastewater is escalated due to the rapid growth of lithium-ion batteries (LIB) as power storage in personal electronic devices. Herein we report a novel cobalt-based draw solute, Co-Bet-Tf2N, synthesized from lithium-ion battery (LIB) wastes, in a forward osmosis (FO) process to purify Co2+-containing wastewater discharged from the LIB industry. Co-Bet-Tf2N possesses abundant -NMe3+ groups and releases multiple ionic species in water, allowing it to produce a high osmotic pressure to drive FO separation efficiently; meanwhile its three-dimensional structure prevents the reverse Co-Bet-Tf2N diffusion in FO experiments. Consequently, a dilute Co-Bet-Tf2N solution (0.2 mol/L) generates a water flux as high as 14.7 LMH along with a negligible solute loss (< 0.02 g/L), outperforming other reported draw solutes. Moreover, Co-Bet-Tf2N extracts water from the Co2+-containing wastewater more efficiently with a water flux 232 % and 174 % higher than those of the conventional NaCl and MgCl2 draw solutes, respectively. Particularly, Co-Bet-Tf2N is easily regenerated via the [Hbet][Tf2N]-based extraction without energy input, thus more practical than the recycling of other draw solutes reported elsewhere. This study not only demonstrates the superiority of Co-Bet-Tf2N as a novel draw solute, but achieves effective waste reuse and wastewater reclamation.

Abstract ：
Polyamide (PA) membrane is extensively used in various membrane separation processes due to its easy preparation, high selectivity and good acid-base stability. However, the PA material is vulnerable to the attack of free chlorine which causes PA chlorination degradation and eventually damages the membrane selectivity. As such, developing chlorine-resistant membrane has become a research focus in membrane technology recently. This accelerates the emergence of a large number of novel PA membranes. However, reviews on this aspect are quite rare to date. Thus, providing an updated critical review on the PA-based anti-chlorine membrane is highly needed. This paper aims to critically review the recent development in the PA chlorine-resistant membrane designed specially via the modification of the PA selective layer. The recent advances in the PA anti-chlorine membranes are briefly introduced first. The mechanism and influential factors of the chlorination of PA membrane are subsequently presented. The strengths and limitations of the recently developed PA anti-chlorine membrane are critically evaluated afterward. The challenges and future research directions of the sustainably chlorine-resistant PA membranes are finally discussed. This article can provide insightful guidance for the future development of the PA-based chlorine-resistant membrane. © 2023 The Authors

Abstract ：
The current Covid-19 aggravates membrane biofouling issue caused by bacteria and viruses which are widely present in water. Herein we synthesized a series of polyamide (PA)-based membranes engineered with distinct metal ions (Cu2+, Fe3+) via one-step metal-ligand ligation for forward osmosis (FO) separation. The antibacterial and desalting behavior of membrane were investigated by systematically varying the influential factors including the charge status, complexation ability and antibacterial mechanism of metal ions as well as testing conditions. All the newly synthesized membranes exhibit better performance with markedly increased water permeability and selectivity. Therein the Fe3+ - membrane increases water fluxes by 93% (FO mode) and 112% (PRO mode) relative to the nascent PA membrane with 0.5 M NaCl as the draw solution. Both Cu2+ and Fe3+ on membrane surface dramatically improve the membrane bactericidal efficacy against Escherichia coli via destroying the bacterial phospholipid layer. Remarkably, the metal ions on membrane surface are easily regenerated after being consumed by bacteria by simply immersing the membranes into the corresponding nitrate solutions. The separation performance and antibacterial properties of the regenerated membranes are comparable to those of the fresh membranes.
