Summary: Increased contamination of aquatic ecosystems with pharmaceuticals was observed during the COVID-19 pandemic. Surface water from different domains along the Mreznica River in Croatia was analyzed, and significant concentrations of drugs were detected. The contamination levels were higher in urban areas compared to semirural and rural areas. As the pandemic progressed, contamination increased at all sites, with the highest increase observed in semirural areas. The study found that the behavior and habits of the inhabitants in the affected areas, as well as the implementation of epidemiological measures and medical treatments, contributed to the surface water contamination.

Summary: In the past decade, the removal of pharmaceuticals from aquatic bodies has received significant attention. Ibuprofen (IBP), a commonly used anti-inflammatory drug, is released into the environment through pharmaceutical waste and wastewater. Adsorption technology using carbonaceous materials has been found to be highly effective in reducing IBP in low concentrations. This comprehensive review examines the use of various carbonaceous adsorbents for IBP removal, including activated carbon, biochar, graphene-based materials, and carbon nanostructures. The studies compiled in this review indicate that some carbon-based adsorbents have higher IBP uptake than commercial activated carbons. More attention is needed for practical application and scaling up of these research findings to support water resource management and sustainability.

Summary: This paper investigates extended end-plate connections equipped with shape memory alloy bolts. A hybrid connection, using shape memory alloy bolts for the outer rows and conventional HSS bolts for the remaining rows, improves the energy absorption capability. Conventional and hybrid connections have better energy absorption capabilities compared to shape memory alloy connections. Increasing pre-stressing over 50% f(y) has no significant effect on the cyclic performance of connections.

Summary: In recent years, various industries have been releasing large amounts of saline wastewater into the environment. This study investigated the electrochemical removal of nitrogen compounds from synthetic saline wastewater using a laboratory-scale experimental reactor. The experiments examined the effects of operational parameters, such as electrolyte composition and concentration, applied current intensity, and initial ammoniacal nitrogen concentration, on the efficiency of total nitrogen removal. The results showed that using NaCl as the electrolyte resulted in higher total nitrogen removal than Na2SO4 and NaClO4, but increasing the initial NaCl concentration above 250 mg/L did not improve the removal efficiency. Increasing the current intensity from 0.05 A to 0.15 A improved the removal efficiency, but further increasing it to 0.25 A did not enhance the efficiency. Lower initial ammoniacal nitrogen concentrations led to higher removal efficiency. The highest total nitrogen removal (approximately 75%) was achieved after 90 minutes of treatment with a NaCl concentration of 250 mg/L, an applied current intensity of 0.15 A, and an initial ammoniacal nitrogen concentration of 13 mg/L. The proposed nitrogen degradation mechanism assumed a series-parallel reaction system with NH4+ in equilibrium with NH3 as the first step. The nitrogen molar balance showed that the main product of nitrogen oxidation was N-2, but NO3- was also detected. Overall, electrochemical treatment shows promise for the removal of nitrogen compounds from saline wastewater.

Summary: In this study, a methodology combining experimental and modeling approaches is proposed to design chemical absorption columns with fast gas-liquid reactions. The methodology considers thermodynamic data, mass-transfer phenomena, and reaction kinetics. The absorption of SO2 in aqueous solution of H2O2 is investigated, and the solubility dataset is evaluated using a lab-scale fed-batch bubble column. A thermodynamic model is developed and validated using Aspen Plus. Kinetic experiments are carried out using a lab-scale falling-film absorber to determine the mass-transfer rates and kinetic aspects of the absorption process. The results are correlated with the Hatta number using the Danckwerts kinetic model. (c) 2023 Institution of Chemical Engineers. Published by Elsevier Ltd. All rights reserved.

Summary: In this study, pilot-scale tests were conducted on a new design of Y-type corrugated polylactic acid (PLA) packing produced by a one-step 3D foam-printing process. Experimental tests showed that the FT.Y packing exhibited comparable or superior performance to the benchmark commercial Mellapak 250Y packing in terms of pressure drops and mass transfer coefficients. The FT.Y packing also demonstrated higher desulfurization efficiencies in wet Flue Gas Desulfurization than the benchmark packing. Overall, the 3D foam-printed FT.Y packing shows great potential in process intensification for absorption and distillation processes.

Summary: In recent years, the discharge of emerging pollutants in water and wastewater has become a significant human problem. Water pollution poses potential risks to human health and the environment, and efficient methods are needed to remove contaminants. Electrochemical oxidation (EO) is a commonly used method for removing persistent pollutants from wastewater, but there are still gaps in knowledge regarding the process and costs. This paper discusses the impact of operational parameters on EO performance, compares different electrochemical reactor configurations, analyzes cost and energy consumption, and explores the combination of EO with photocatalysis. The study highlights the importance of optimizing operating conditions and developing innovative approaches to address water pollution.

Summary: The photoactivated periodate (UV/IO4-) process was used to degrade acid orange 10 (AO10) dye. Periodate ions produce reactive radicals that accelerate the degradation. Increasing initial periodate concentration enhances dye removal rate, but concentrations over 3 mM slow down the degradation. On the other hand, increasing initial dye concentrations reduces the degradation performance. pH is critical for AO10 breakdown. Salts slow down dye degradation, while UV/IO4- is more efficient in distilled water. Surfactants and sucrose affect the dye's decomposition rate. Tertbutanol does not affect dye breakdown, indicating a non-(OH)-O-center dot pathway. The UV/IO4- system eliminates 56.5% and 60.5% of initial COD after 60 and 120 min, suggesting its effectiveness for treating effluents with textile dyes.

Summary: The use of machine learning to predict the performance of specific adsorbents in phosphate adsorption shows great promise in saving time and revealing underlying mechanisms. However, the small size of the dataset and insufficient detailed information limits the model training process and the accuracy of results. To address this, the study employs a fuzzing strategy that replaces detailed numeric information with descriptive text messages on the physiochemical properties of adsorbents. This strategy allows the recovery of discarded samples with limited information, leading to accurate prediction of adsorption amount, capacity, and kinetics. The study also finds that phosphate uptake by adsorbents is generally through physisorption, with some involvement of chemisorption. The framework established in this study provides a practical approach for quickly predicting phosphate adsorption performance in urgent scenarios, using easily accessible information.
