Summary: This study evaluates the performance of a ceramic microfiltration membrane for extracting clean water and pre-concentrating microalgae. The results show that membrane fouling is specific to each microalgae species, but can be efficiently mitigated by aeration and regular backwashing. C. vulgaris exhibited considerable membrane fouling over time, while Scenedesmus sp. showed negligible fouling. The ceramic microfiltration membrane can simultaneously enrich the microalgae solution and recycle permeated water for microalgae cultivation.

Summary: The study found that increasing transmembrane pressure can result in higher permeate flux and lower resistance, while high crossflow velocity can lead to a release of extracellular organic matter causing severe membrane fouling. Additionally, membrane configuration and pore size significantly affect permeate flux, with multichannel ceramic MF membranes demonstrating higher flux and lower fouling.

Summary: This study evaluated the alleviation of membrane fouling for the treatment of shale gas produced water (SGPW) using sodium percarbonate oxidation and aluminum sulfate coagulation. The results showed that the combination of oxidation and coagulation effectively reduced turbidity, UV254, and DOC, as well as fluorescent organics in the SGPW samples. The normalized fluxes were significantly improved compared to the raw SGPW, indicating the potential of this combined pretreatment process in controlling membrane fouling.

Summary: This study successfully synthesized MIL-53(Al) adsorbents through sonochemical-assisted synthesis and investigated their application in removing lead ions from aqueous solutions. The results showed that sonochemical-assisted synthesis could significantly reduce the synthesis time and increase the specific surface area of the adsorbents, thereby improving the mass transfer limitation in ion adsorption. The optimal conditions for lead ion removal were determined, and the applicability of adsorption equilibrium and kinetic models were verified. Furthermore, this study demonstrated the great potential of sonochemically synthesized MIL-53(Al) as an environmentally-friendly adsorbent for lead ion removal.

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.

Summary: This study investigated the operation of a 1000L microalgae-based membrane photobioreactor system for continuous secondary wastewater treatment. The research focused on a green microalgae strain called Desmodesmus sp. The study aimed to understand key trends and optimization strategies by conducting experiments in both summer and winter seasons. The findings showed that maintaining low cell concentrations during periods of light inhibition was beneficial for nutrient uptake rates. Effective strategies for enhancing algae-based wastewater treatment included cell mass recycling and adjusting dilution rates based on light availability.
