Summary: This study uses biological treatments in gas treatment to enhance efficiency by maximizing mass transfer from gas to liquid. VOCs are removed through absorption in a gas-liquid contactor before entering a Two-Phase Partitioning Bioreactor (TPPB). The use of Non-Aqueous Phase Liquid (NAPL), such as silicone oil, allows for solubilizing hydrophobic VOCs without toxicity effects on microorganisms. The aim of the study is to provide a designing tool for the degradation process in the TPPB, which involves simulations considering mass transfer and biodegradation kinetics.

Summary: This study investigated the performance of SBR in the biodegradation and mineralization of atenolol, a widely used beta-blocker. The results showed that SBR was able to efficiently remove atenolol and COD under optimal conditions. The study also identified one of the main pathways of atenolol biodegradation. Comparison with existing literature demonstrated that SBR was more effective in removing higher concentrations of drugs. Therefore, SBR could be considered as a promising technique for treating wastewaters containing atenolol and other beta-blocker drugs.

Summary: Treatment of industrial wastewaters can be challenging due to toxic and persistent compounds and unfavorable pH conditions. Extractive membrane bioreactor (EMB) is a promising technology capable of overcoming these difficulties. This review analyzes earlier PDMS and newest polymeric membrane reactors, highlighting their potentialities and research issues. Factors such as biofilm formation, reactor configuration, and operative parameters greatly affect reactor performance and further investigations are needed. Data analysis shows that this technology is ready for upscaling, which is crucial for evaluating its feasibility in industrial wastewater treatment.

Summary: This research article presents a method for the removal of toxic substances from contaminated water using heterojunctions. The CuO/SnO2 heterojunction was constructed using a green synthesis route and characterized using various techniques. The results showed that the CuO/SnO2 heterojunction exhibited excellent catalytic performance under sunlight irradiation, effectively converting toxic 4-NP into harmless 4-AP. Additionally, the heterojunction demonstrated efficient removal of Mn2+ ions from industrial effluents.

Summary: An integrated lab-scale wastewater treatment system was used to study the removal and fate of pharmaceuticals during wastewater treatment. The removal of major pollutants and target pharmaceuticals was not affected by the temperature of the anaerobic Moving Bed Biofilm Reactor (AnMBBR). Biotransformation was the predominant mechanism for the removal of pharmaceuticals, while sorption played a minor role.

Summary: In this study, Bacillus licheniformis immobilized with low-density polyethylene (LDPE) was used to degrade Brilliant Green (BG) dye from wastewater in a packed bed bioreactor. The effects of different concentrations of BG dye on bacterial growth and extracellular polymeric substance (EPS) secretion were assessed. The impacts of external mass transfer resistance on BG biodegradation were also evaluated. A new mass transfer correlation was proposed and intermediates during the biodegradation of BG were identified.

Summary: The main aim of this study was to optimize and maximize the impacts of biodegradation of odor and volatile organic compounds (VOCs) in a wastewater treatment plant using a compact trickle bed bioreactor (CTBB) on a pilot scale. The CTBB was tested with gases from a tank containing semi-liquid fats, oils, and fat waste and showed pollutant removal efficiency ranging from 81.5% to 99.5% for VOCs, 87.5% to 98.9% for H2S, and >99% for NH3. In the liquid phase, the removal efficiency was higher at pH = 7.0 than at pH = 5.0.

Summary: Membrane reactors for pure hydrogen production are complex systems that rely on the interplay between convection, dispersion, hydrogen permeation, and reaction kinetics. Simplified models have been developed to adequately describe the system while keeping computational costs low. This study aims to derive an enhanced Sherwood number to account for changes in composition due to reaction and permeation along the reactor.

Summary: Anaerobic biodegradation of toxic compounds in industrial wastewater is an attractive solution for energy and resource recovery, but faces challenges due to low kinetics compared to aerobic processes. Research on anaerobic phenol degradation focuses on microbiological and technological aspects to enhance competitiveness, with a gap still existing between aerobic and anaerobic performance. Efforts are needed to develop powerful technologies and effective strategies to improve the anaerobic process and move towards more sustainable wastewater treatment.

Summary: This study investigated the thermal stability of a commercial terphenyl-based oil, revealing that the main decomposition mechanism involves the loss of hydrogen atoms and partial polymerization processes, explaining the increase in dynamic viscosity and decrease in volatility observed for the thermally stressed materials. Additionally, the study estimated the decomposition kinetic constants for the oil.

Summary: This study investigated the anaerobic fermentation of real waste activated sludge under high organic loading rate and short hydraulic retention time, finding that the quantity of EPS recovered increased over time while the chemical oxygen demand to EPS ratio remained consistent. Slightly acidic conditions and sludge floc disintegration promoted the disruption and release of EPS matrix, along with the solubilisation of organically bound toxic metals, leading to increased overall metal removal efficiency. Bacteroidetes, Firmicutes, and Chloroflexi were identified as the most abundant phyla, indicating that the short HRT favored the hydrolytic and acidogenic activity of these taxa.

Summary: Membrane reactors are two-dimensional systems with varying concentrations due to reaction and membrane permeation. A new expression for enhanced Sherwood number has been developed to describe hydrogen concentration gradients. Further analysis is needed to evaluate the simplifying assumptions of the 1D model and identify operating conditions for its use with the enhanced Sherwood number.

Summary: Membrane reactors are two-dimensional systems that require complex models for accurate description of transport phenomena. However, when mass transport within the reactor is the limiting factor, a simplified 2D model can be used. The study shows that this simplified model has an analytical solution for concentration profile or can be reduced to a 1D model with an enhanced Sherwood number, depending on the stoichiometry of the reaction.
