Summary: Textile industries produce wastewater with harmful azo dyes that are known to be carcinogenic and mutagenic. This study evaluates the potential use of enzyme immobilized biochar for removing azo dyes from real and simulated textile effluents. The results show that the enzyme immobilized system can achieve high removal efficiency for individual azo dyes in the simulated effluent and for one dye peak in the real effluent. The presence of metabolite in the real effluent indicates the degradation of the dye. Therefore, enzyme immobilized biochar system can be used for simultaneous adsorption and degradation of toxic azo dyes from real effluents.

Summary: In this study, an ICPB system consisting of BiOBr/modified g-C3N4 (M-CN) and biofilms was developed for the treatment of oil spills. The results showed that the ICPB system achieved a rapid degradation of crude oil, surpassing single photocatalysis and biodegradation methods. The combination of BiOBr and M-CN formed a Z-scheme heterojunction structure, enhancing the redox capacity and accelerating the degradation process of crude oil. Moreover, the ICPB system maintained a high degradation ratio after three cycles and the biofilms adapted to the adverse effects of crude oil and light.

Summary: This review focuses on the integrations of various advanced oxidation processes (AOPs) with biodegradation for the treatment of textile azo dyes, aiming to reduce the processing cost and improve the degree of mineralization. Results show that ozone treatment alone is the most efficient in decolorization, while all three AOPs independently offer varied and inadequate COD reduction. The integration of AOPs with biodegradation further reduces COD and TOC levels, and has the potential to significantly reduce treatment costs. The review suggests further research in sequencing chemical and biological routes for complete detoxification of textile azo dyes.

Summary: Spinel MgAl2O4 nanospheres prepared by the combustion method were coupled with thermally-exfoliated g-C3N4 nanosheets (TE-GCN) through an efficient isoelectric point-assisted calcination technique. The synthesized nanocomposite exhibited improved electron-hole separation, leading to enhanced degradation of the RR195 dye contaminant. The optimal conditions for complete degradation were achieved at pH 3.0 with a photocatalyst dosage of 0.9 g/L and a duration of 70 minutes under simulated sunlight illumination. The TE-GCN@MgAl2O4 photocatalyst demonstrated high stability with only a negligible reduction in photodegradation efficiency after 5 consecutive catalytic reaction cycles.

Summary: Natural selection was used to enrich microbial consortia capable of utilizing lignin as the sole carbon source, resulting in a decrease in bacterial richness and diversity after the enrichment protocol. The type of lignin used as a carbon source had a greater impact on differentiating the bacterial consortia than the variable temperature. Selected bacterial genera for lignin utilization included Altererythrobacter, Bacillus, Pseudomonas, and others.

Summary: This study investigated the decolorization efficiency of selective reactive azo dyes by non-adapted Lysinibacillus sphaericus MTCC 9523 in optimized conditions, with visual color changes and spectroscopic analysis confirming decolorization. HPLC analysis showed differences in retention time between control and treated samples, supporting biodegradation, while GC-MS analysis revealed the chemical identities of metabolites and predicted the metabolic pathways of degradation for each dye. Overall, the use of adapted and non-adapted microbes is a promising, cost-effective and time-saving green strategy for the biodegradation of textile effluent containing azo dyes.

Summary: This study investigated the anti-fouling performance of PVDF-TiO2 composite membranes in different types of synthetic feed solutions. The results showed that inorganic fouling was unlikely to occur on the membranes, except for the presence of a small amount of Cu2+ coexisting with HCO3- in the feed solution. The membranes also showed strong resistance to sodium alginate fouling, but less resistance to humic acid fouling. The study also found that the membranes did not show advantages in terms of separation efficiency when operated in photo-filtration mode.

Summary: This study investigates the impact of pre-ozonation of real MBR effluent on nanofiltration performances. The results show that ozonation has a low effect on organic carbon mineralization, but it effectively degrades specific organic matter fractions. Pre-ozonation has a beneficial effect in reducing membrane fouling and flux decrease. This study suggests that partial mineralization of organic matter through ozonation can be beneficial in reducing inorganic scaling and severe NF membrane fouling.

Summary: Recently, ozonation with hollow fiber membrane contactors (HFMC) has shown the potential to effectively remove emerging contaminants while minimizing the formation of regulated by-products like bromates. This study investigated the ozonation of real-treated wastewater using a HFMC and bubble columns, comparing their pharmaceutical abatement and bromate minimization performance. The results showed that HFMC achieved 100% abatement of p-chlorobenzoic acid (p-CBA), producing significantly less bromate compared to bubble columns. Short contact times resulted in high pharmaceutical removal rates without bromate formation.

Summary: In this study, PVDF-based anion-exchange membranes were designed to selectively separate nitrate from chloride. Experimental data showed that increasing the concentration of PVDF enhanced nitrate transport but also increased the membrane electrical resistance. The selectivity of nitrate was found to be independent of the membrane thickness and mainly driven by the increased affinity between the anion and the membrane.

Summary: This study focuses on the modification of a commercially available polyamide thin-film composite membrane with a zwitterionic material to enhance its fouling resistance. The modified membrane shows improved salt rejection and reduced permeability compared to the pristine membrane. Fouling tests demonstrate that the modified membrane has a lower fouling ratio and higher recovery ratio. The enhanced antifouling characteristics are attributed to the improved hydrophilicity resulting from the zwitterionic brushes and the salting-in effect.

Summary: A transmembrane electro-chemisorption system with authigenic acid and base was developed for enhancing ammonia recovery from strong ammonia wastewater. The system efficiently transformed ammonium into free ammonia, which was then adsorbed and recovered through transmembrane chemisorption. This system yielded pure (NH4)2SO4 product and produced valuable byproducts of pure hydrogen and oxygen. Higher applied voltage resulted in better ammonia recovery.

Summary: To meet the huge demand for lithium resources, there is an urgent need to develop a new efficient technology for lithium recovery from salt-lake brines. In this study, a selective membrane capacitive deionization system is reported, which achieves high lithium recovery capacity and rate through the use of materials with efficient intercalated pseudo-capacitance and a high specific area porous carbon. The use of a modified thin-coated membrane allows for selective Li+ recovery, and adjusting the concentrations of Li+ and Mg2+ in the feed solution enables higher Li+/Mg2+ selectivity.

Summary: In this study, a novel polydopamine-functionalized lignin-containing pulp foam evaporator with high-efficiency desalination and multi-contaminant adsorption capabilities was designed. The foam evaporator showed excellent light absorption, water absorption, thermal conductivity, and chelation abilities, allowing for solar evaporation and contaminant adsorption synergistically. It also exhibited potential applications in metal ion concentration and contaminated seawater treatments, and demonstrated superior biodegradability compared to poly-styrene foam. This foam material holds promise for developing multifunctional photo-thermal systems for solar-driven water purification.
