Summary: The aim of this research was to study the potential for degradation of Reactive Blue 214, Reactive Red 195, and Reactive Yellow 145 using a dye degrading bacterium, identified as Klebsiella pneumoniae MW815592. The strain completely decolorized artificial effluent (200 mg/L) after 42 hours at pH 9 and 46 degrees C. The decolorization rate increased in the presence of glucose and yeast extract (2 g), and it was found to be due to biodegradation rather than adsorption on the bacterial surface.

Summary: Azo dyes, widely used in textile industries, are difficult to degrade due to their xenobiotic nature. However, recent studies have shown that many microorganisms can convert these toxic azo dyes to non-colored compounds or even mineralize them under specific environmental conditions. This study evaluated the decolorizing efficiency of newly isolated Paramecium species in textile industrial wastewater containing azo dyes. The results showed that Paramecium species had a high decolorization rate under optimum conditions, making them potentially useful for bioremediation of textile-dying industry effluents.

Summary: In this study, a sustainable precursor, raw clay (RC), was obtained from the Amazon region in Brazil and purified to form a clay-based adsorbent (CBA). The CBA was characterized using various techniques and used to remove basic yellow 2 (BY2) dye from aqueous solutions, achieving a removal rate of 98% under optimal conditions. The correlation between quantum chemical descriptors and experimental results suggests that BY2 dye is adsorbed on the CBA surface through electrostatic interactions.

Summary: This study aims to find a solution to the dye-based pollution problem and contribute to the decontamination of RB222-originated impurities. Classical electrocoagulation and ultrasound-associated electrocoagulation methods were used to evaluate the effects of process parameters on dye decolorization and degradation. Optimal values were determined based on the efficiency of dye removal. Both EC and USEC processes achieved complete decolorization with high removal efficiency, especially at low current densities and high dye concentrations. The USEC process significantly reduced operation time compared to the EC process, particularly at the beginning of decolorization.

Summary: This study successfully overexpressed the AzK gene in Escherichia coli for the efficient degradation of Remazol Red-R and Acid-Blue 29 dyes. Optimal conditions were determined as 1.5% inoculum size, 0.5 mM IPTG concentration, and 6 hours incubation time. The crude extract achieved 76% and 74% decolorization of RRR and AB-29, while the purified enzyme achieved 94% and 93% decolorization within 0.3 hours. Kinetic analysis revealed the enzymatic characteristics and HPLC and GC-MS analyses confirmed the effective biotransformation of dyes into less toxic metabolites. This study highlights the potential of recombinant azoreductase for the degradation of textile azo dyes.

Summary: This study aimed to enhance the decolorization of anthraquinone dye by designing an immobilized system. Reactive blue 4 (RB4) was used as the substrate and a previously isolated dye-degrading strain was immobilized. Polyurethane foam (PUF) with open pore structure was selected as the carrier. The results showed that the RB4 decolorization efficiency was significantly improved after immobilization. The PUF-immobilized system exhibited good performance in a packed bed bioreactor (PBBR), with a high decolorization efficiency that could be maintained for 26 days.

Summary: In this study, the degradation of BV16 dye in aqueous solution using the LGDP/Cl-/O-2 system was investigated. The system significantly facilitated the degradation of BV16 due to the involvement of UV irradiation and reactive species. Reactive oxygen species and reactive chlorine species were generated, and oxygen injection was found to accelerate the production of ROS. The decay pathway of BV16 in the LGDP system was proposed, showing the formation of simple aromatic compounds and low molecular weight acids which could eventually be mineralized.

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.

The effect of temperature on water permeate flux, specific energy, permeate quality, and applied operating pressures is evaluated using an analytical model. The results suggest that under specific conditions, the tradeoff between savings in mechanical pump work and thermal energy input in thermally-enhanced RO can be favorable, leading to overall energy savings.

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.
