Summary: Two extremophilic biosorbents were used to successfully remove Cu(II), Ni(II), and Pb(II) from aqueous solutions. The biosorbents showed high affinity for these metal ions, with removal rates ranging from 73.6% to 100%, and the removal order was Pb(II) > Cu(II) > Ni(II). Both Langmuir and Freundlich models were suitable for describing the adsorption process, with the pseudo-second-order reaction model being more accurate than the pseudo-first-order model kinetically.

Summary: Sustainable waste management practices involve utilizing renewable resources for waste disposal. This study found that waste derived from pineapple can be used as a biosorbent for removing cobalt ions from water. Batch and column studies showed that modified pineapple waste exhibited good removal performance. Kinetic and equilibrium data were best described by the pseudo-second-order and Freundlich isotherm, respectively, while column data fitted well with the Yoon Nelson model. Thomas's model successfully described the behavior of the pineapple waste in removing cobalt ions from real wastewater.

Summary: The study found that Spirulina has higher removal capacity at pH 5.2 and lower adsorption capacity at higher ionic strength, suggesting ion exchange as a relevant mechanism. Immobilizing Spirulina on alginate beads not only increases adsorption capacity but also overcomes limitations in column systems. Dose-response model was the most appropriate to describe the biosorption process.

Summary: The goal of this study was to investigate the adsorption of Cd(II) and Ni(II) ions using biomass from polluted sites. Results showed that biomass could be used to adsorb these ions and pretreatments enhanced the activation of functional groups in the biomass. Under the conditions of pH 7.0 and metal ion concentration of 1.0 g/L, the removal efficiency of Cd(II) reached 55% with autoclaved biomass, while activated carbon achieved only 13%. This highlights the importance of low-cost adsorbents and suggests the potential for industrial activities to utilize contaminated sites for wastewater treatment.

Summary: Green alga Neochloris oleoabundans cultivated in medium of varied phosphate concentration showed effective biosorption capacity for Cu(II) removal from aqueous solutions. The highest biosorption capacity of 180.19 mg-Cu/g-biomass was achieved with biomass grown in medium containing 300 mg/L K2HPO4. The Cu(II) biosorption was fast with equilibrium established within 10 min of contact time, and Cu(II)-induced cell aggregation could facilitate biomass recovery.

Summary: This study analyzed a magnetite-chitosan composite through various techniques and explored its adsorption properties for Cu(II) and Cd(II). The results showed that the optimum pH for adsorption was 5.0, the equilibrium time was about 10 minutes, and the adsorption capacity reached 26.28 mg/g for Cu(II) and 18.67 mg/g for Cd(II). The temperature had a certain impact on the adsorption amount, and the composite material had a relatively rough outer surface, with dominant adsorption being attributed to chitosan. The research suggests the importance of further optimizing the composite system through green synthesis for heavy metal adsorption.

Summary: This study aimed to integrate multiple hydrogen peroxide activation mechanisms for reactive oxygen species generation towards the removal of contaminants of emerging concern in a continuous-flow unit. The combination of UVC/H2O2/TiO2 system with radial addition of H2O2 and multiple TiO2-P25 layers achieved high efficiency in removing the antibiotic amoxicillin. Urban wastewater matrix negatively affected the removal of amoxicillin due to the presence of ROS scavengers and light-filtering species.

Summary: The study evaluated marine macroalgae waste as feedstock for anaerobic digestion processes, finding that the highest biogas volume and methane concentration were obtained at a total solids content of 2.5% TS. The experiments showed an average of 43% COD reduction and 46% VS reduction after 57 days, corresponding to about 27% of the theoretical maximum methane production. However, inhibition of the process was observed when using 3.5% TS, likely due to the accumulation of volatile fatty acids.

The shells contain polyphenols, which can be extracted and used for various applications, including water treatment coagulants. In this study, tannin extraction from chestnut shells was optimized using a microwave-assisted method. The best extraction conditions were determined as a 5-minute extraction time, a liquid-to-solid ratio of 50 mL/g, and a temperature of 107 degrees C. The extracted polyphenols showed good features for use as raw materials in water treatment coagulants.

Summary: This study investigated the impact of the non-antibiotic pharmaceutical carbamazepine on antibiotic resistance genes (ARGs) during anaerobic digestion. The results showed that carbamazepine induced the enrichment of ARGs and increased the abundance of bacteria carrying these genes. It also facilitated microbial aggregation and intercellular communication, leading to an increased frequency of ARGs transmission. Moreover, carbamazepine promoted the acquisition of ARGs by pathogens and elevated their overall abundance.

Summary: This paper developed a machine learning model to predict the biochemical methane potential during anaerobic digestion. Model analysis identified lignin content, organic loading, and nitrogen content as key attributes for methane production prediction. For feedstocks with high cellulose content, early methane production is lower but can be improved by prolonging digestion time. Moreover, lignin content exceeding a certain value significantly inhibits methane production.
