Abstract ：
Synthetic dyes are used in various industries including textile processing, food production and the pharmaceutical sector. Yet, approximately 80% of the dye-containing wastewaters produced are often released untreated into waterways or used directly for irrigation, causing detrimental impacts on human health and ecosystems. In this Review, we discuss the environmental impact of dye-containing wastewater and explore the chemical, biological and physical mitigation strategies used to treat and decontaminate dye-containing wastewaters. Untreated synthetic dyes cause coloration of receiving water bodies, hindering the degree of visible light reaching the photic ozone, and have carcinogenic, mutagenic and teratogenic properties that have toxic impacts on plants, animals and humans. Chemical treatment methods such as coagulation are the most widely adopted treatment methods; however, they require careful sludge management to be effective. Biological degradation, involving the implementation of enzymes, microorganisms and plants, is an environmentally friendly and energy-efficient approach for dye degradation, but it requires lengthy reaction times and the use of selective bio-organisms for target dyes. Advanced membrane-based physical separation can achieve effective removal of dyes and inorganic salts from highly saline dye-containing wastewater, while also enabling their recovery and reuse. Strengthened regulatory requirements and development of non-toxic dyes are required in conjunction with these remediation treatments to effectively mitigate dye-related pollution. Wastewater dyes from textile, food and pharmaceutical industries are a major environmental concern. This Review discusses the environmental impacts of dye-containing wastewater and explores both conventional and emerging remediation strategies. Untreated synthetic dyes released into aquatic environments reduce the light available for photosynthesis by primary producers, with consequential impacts for the whole food chain. In addition, dyes are also directly harmful to plants, animals and humans, with human health implications including increasing allergy and cancer risk.Chemical coagulation and electro-coagulation are widely adopted methods of dye removal. However, coagulant efficacy and sludge management are crucial for efficient removal of dyes.Advanced oxidation processes, which encompass chemically mediated advanced oxidation processes, photocatalysis and electrocatalysis, have been proven effective at dye degradation. To ensure these methods are sustainable and safe, it is crucial to minimize chemical and energy consumption and monitor and manage the toxic by-products that can be generated during the process.Biological degradation is an eco-friendly and energy-efficient method for dye removal through the utilization of enzymes, microorganisms (bacteria, fungi, yeast and algae) and plants, but these methods require a long reaction time, owing to slow kinetics during dye degradation.Emerging membrane-based physical separation techniques, including tight ultrafiltration, loose nanofiltration and electro-driven nanofiltration, show a great potential in fractionation of dyes and salts from highly saline dye-containing wastewater. These methods also enable efficient recovery of dyes and salts to promote a circular economy in the textile sector.To achieve sustainable and safe synthetic dye use, these advanced remediation technologies must be implemented in combination with proper regulation of dye-containing wastewater discharge in collaboration between governing bodies and industry stakeholders.

Abstract ：
Under the environmental sustainability concept, landfill leachate concentrate can be up-cycled as a useful resource. Practical strategy for effective management of landfill leachate concentrate is to recover the existing humate as fertil-izer purpose for plant growth. Herein, we designed an electro-neutral nanofiltration membrane to separate the humate and inorganic salts for achieving a sufficient humate recovery from leachate concentrate. The electro-neutral nanofiltration membrane yielded a high retention of humate (96.54 %) with an extremely low salt rejection (3.47 %), tremendously outperforming the state-of-the-art nanofiltration membranes and exhibiting superior promise in fractionation of humate and inorganic salts. With implementation of the pressure-driven concentration process, the electro-neutral nanoltration membrane enriched the humate from 1756 to 51,466 mg & BULL;L-1 at a fold of 32.6, enabling 90.0 % humate recovery and 96.4 % desalination efciency from landll leachate concentrate. Furthermore, the recovered humate not only exerted no phytotoxicity, but also signicantly promoted the metabolism of red bean plants, serving as an effective green fertilizer. The study provides a conceptual and technical platform using high-performance electro-neutral nanoltration membranes to extract the humate as a promising nutrient for fertilizer application, in view of sustainable landll leachate concentrate treatment.

Abstract ：
A key to sustainable management of saline organic-rich wastewaters is to precisely fractionate organic components and inorganic salts (NaCl) as individual resources. Conventional nanofiltration and electrodialysis processes suffer from membrane fouling and compromise the fractionation efficacy. Here we develop a thin-film composite nanoporous membrane via co-deposition of dopamine and polyethyleneimine as a highly anion-conducting membrane. Experimental results and molecular dynamics simulations show that co-deposition of dopamine and polyethyleneimine effectively tailors the membrane surface properties, intensifying the charge shielding effect and enabling fast anion transfer for highly efficient electrodialysis. The resulting nanoporous membrane exhibits unprecedented electrodialytic fractionation of organics and NaCl with negligible membrane fouling, dramatically outperforming state-of-the-art anion exchange membranes. Our study sheds light on facile design of high-performance anion-conducting membranes and associated new mass transport mechanisms in electrodialytic separation, paving the way for sustainable management of complex waste streams.

Abstract ：
Conventional membrane processes, e.g., microfiltration and ultrafiltration, suffer from severe permeation flux decline and fouling during the oily wastewater treatment. The superhydrophilic surface decoration provides an important and effective strategy to address this challenge. Herein, a surperhydrophilic/underwater superoleophobic nanocomposite surface with the photocatalytic properties was constructed via one-step facile vacuum-assisted filtration of a g-C3N4 nanosheet/SiO2 nanoparticle dispersion onto a microfiltration membrane substrate. Specifically, with the intercalation of 20 mg.L-1 SiO2 nanoparticles into the g-C3N4 nanosheets, the g-C3N4/SiO2 composite membrane showed the superhydrophilic/underwater superoleophobic properties with an underwater oil contact angle of 170.0 +/- 0.3 degrees. Such a g-C3N4/SiO2 composite membrane yielded a permeation flux of >1290 LMH.bar(-1) with an oil rejection of >99.91% during the vacuum filtration of oil-in-water emulsions. The g-C3N4/SiO2 composite membrane significantly outperformed the pristine microfiltration substrate that had severe fouling caused by oil blockage. Additionally, the g-C3N4/SiO2 composite membrane not only effectively retained the E. coli bacteria through size exclusion effect, but also promoted the inactivation of bacteria via visible-light photocatalysis. Therefore, our membrane has a great promise in practical oily wastewater treatment due to its excellent separation performance and biofouling resistance.

Abstract ：
Membrane distillation (MD) has been widely used for resource recovery from high-salinity wastewater, due to its superior technical merits of high separation efficiency and potential integration of low-grade heat. Herein, a robust superhydrophobic PVDF membrane prepared by spray-coating of fluorinated silica nanoparticles was employed to treat highly saline dye wastewater by MD. Specifically, impacts of operation conditions, including temperature difference, feed flow-rate, salinity, dye concentration, and dye species, on MD performance of the fabricated super-hydrophobic PVDF membrane were comprehensively investigated. The increase of temperature difference and feed flow-rate had a positive effect on the MD flux of the membrane. Conversely, the rise in salinity and dye concentration induced an adverse impact on the MD flux. Furthermore, the superhydrophobic PVDF membrane showed a strong robustness in treating complex streams, as demonstrated by consistently stable MD flux using various dye/NaCl mixed solutions. Due to the robust surface superhydrophobicity, the fabricated PVDF membrane exhibited impressive antiwetting and antifouling properties against highly saline dye wastewater, consistently stable permeation flux, and high dye/salt removal efficiency (>99.99%). Moreover, the superhydrophobic membrane showed a high water recovery (90%) from highly saline dye wastewater with a slight reduction (13.4%) in permeation flux during a 39 h MD filtration. These results signify the promising practicability of the fabricated superhydrophobic PVDF membrane in sustainable management of highly saline dye wastewater via MD.

Abstract ：
Membrane wetting and fouling substantially limits application and deployment of membrane distillation process. Designing high-performance superhydrophobic membranes offers an effective solution to solve the challenge. In this work, a highly durable superhydrophobic surface (water contact angle of 170.8 +/- 1.3 degrees) was constructed via a facile and rapid spray-coating of extremely hydrophobic SiO2 nanoparticles onto a porous polyvinylidene fluoride (PVDF) substrate for membrane distillation. The superhydrophobic membrane coated by fluorinated SiO2 nanoparticles exhibited a superior physicochemical stability in a wide range of extreme environments (i.e., NaOH, HCl, hot water, rust water, humic acid solution, ultrasonication, and high-speed water scouring). During 8-h continuous membrane distillation desalination experiment, the coated superhydrophobic membrane experienced a consistently stable water vapor flux (ca. 19.1 kg.m(-2).h(-1)) and desalination efficiency (99.99 %). Additionally, such a stable superhydrophobicity endowed the spray-coated PVDF membrane to overcome membrane wetting and fouling during membrane distillation of highly saline solutions containing foulants (i.e., humic acid and rust). Results reported in this study provides a useful concept and strategy in facile construction of robust superhydrophobic membranes via spray-coating for effective membrane distillation.

Abstract ：
Waste management has become an ever-increasing global issue due to population growth and rapid globalisa-tion. For similar reasons, the greenhouse effect caused by fossil fuel combustion, is leading to chronic climate change issues. A novel approach, the waste-to-hydrogen process, is introduced to address the concern of waste generation and climate change with an additional merit of production of a renewable, higher energy density than fossil fuels and sustainable transportation fuel, hydrogen (H2) gas. In the downstream H2 purifying process, membrane separation is one of the appealing options for the waste-to-hydrogen process given its low energy consumption and low operational cost. However, commercial polymeric membranes have hindered membrane separation process due to their low separation performance. By introducing novel two-dimensional materials as substitutes, the limitation of purifying using conventional membranes can potentially be solved. Herein, this article provides a comprehensive review of two-dimensional materials as alternatives to membrane technology for the gas separation of H2 in waste-to-hydrogen downstream process. Moreover, this review article elaborates and provides some perspectives on the challenges and future potential of the waste-to-hydrogen process and the use of two-dimensional materials in membrane technology.
