Summary: The aim of this study was to develop a new, highly compact multi-option photo reactor for the removal of emerging contaminants from wastewater. Different advanced oxidation processes, including electrochemical oxidation, photolysis, and photocatalysis with TiO2 nanotubes array, were investigated and combined to create a photoelectrocatalytic oxidation process. The efficiency of these processes was evaluated by measuring the removal of ofloxacin, a pharmaceutical compound used as a model contaminant. SEM and XRD characterization confirmed the formation of anatase-phase nanotubes with suitable dimensions for photocatalytic reactions. The results demonstrated that the coupling of these technologies was effective, leading to high process efficiencies.

Summary: This study investigated the electrochemical oxidation (EO) technology as an alternative tertiary treatment in wastewater treatment plants (WWTP) to remove contaminants of emerging concern (CECs) and Escherichia coli simultaneously. The results showed that the removal rate of CECs depended on their structure and physicochemical characteristics, as well as the electrode material and shape used. MMO with a higher surface area and circular-mesh electrode exhibited the highest removal efficiency for recalcitrant CECs (20-50%). Varying the current intensity had a minor effect on CECs removal. The overall removal efficiency of CECs exceeded 90% within 2 hours, with simultaneous removal of E. coli. The EO process was considered ecofriendly with a low estimated treatment cost of 1.1 euro/m3.

Summary: The photocatalytic membrane reactor (PMR) has the potential to remove foulants effectively, but current PMR systems face limitations due to membrane fouling and instability. In this study, PdCu alloy deposited on TiO2 incorporated with a polyvinylidene fluoride membrane achieved high rejection efficiency of humic acid (HA) with improved permeation and anti-fouling performance. The alloying effect of PdCu-TiO2 played multiple roles in enhancing PMR performance, including enhancing HA adsorption and improving photocatalytic HA removal, as well as inducing a photothermal effect that enhanced membrane permeation.

Summary: Heterogeneous photocatalysis has shown potential in degrading contaminants of emerging concern (CECs), but there is still limited understanding of the mechanistic implications related to the structural diversity of chemicals. In this study, the degradation extents and rates of selected organics in the presence of reactive oxygen species (ROS) scavengers were determined, and K coefficients were used to correlate the oxidative and reductive degradation pathways. A quantitative structure activity/property relationship (QSA/PR) modeling was then developed to relate the empirical values with the structural features of CECs. The resulting QSA/PR models are robust predictive tools for assessing the distribution of degradation mechanisms in photocatalytic treatment.

Summary: Forward osmosis (FO) with biomimetic hollow fiber module demonstrated high rejection rates for 24 Contaminants of Emerging Concern (CECs), with rejections above 93% and up to 99% observed. While compounds showed close to 100% rejections, they were not fully recovered in the feed solution, necessitating two membrane rinses after each operation for complete recovery. The physicochemical properties of contaminants were considered in the analysis.

Summary: The adsorption efficiency of six CECs onto activated biochars from different lignocellulosic feedstocks was influenced by the porosity and ash content of the biochars as well as the hydrophobic properties of the CECs. The study found that activated wheat straw biochar with high ash content showed the highest adsorption for caffeine and chloramphenicol, while activated softwood biochar with well-developed mesoporosity and low ash content exhibited the highest adsorption for bisphenol A and triclosan.

Summary: This study focuses on the Bi doping effect on ZnO and the microstructure changes induced by the co-doping of Bi and Al in ZnO thin films. The results show that the introduction of Bi and Al can significantly reduce the thermal conductivity of ZnO films, with Bi mainly contributing to grain boundary scattering. However, the coexistence of Bi and Al limits further reduction in thermal conductivity due to morphological changes in the film's microstructure. The findings are important for improving thermoelectric efficiency.

Summary: The main goal of this study was to evaluate the possible reuse routes of effluents from a dairy plant. The water flow in the plant was evaluated and quantified, as well as the water quality parameters required for different industrial activities. A treatment system using a membrane bioreactor and a nanofiltration reactor was considered, and a water pinch analysis was conducted with the collected data using the Water Pinch software. Direct reuse/recycle and regeneration schemes were investigated, with the schemes involving the regeneration of effluents showing the highest reduction in freshwater consumption for the CIP and general processes.

Summary: Different post-synthesis procedures were employed to enhance the performance of a Cu2O/ZnO catalyst for the electrochemical reduction of CO2. The procedures successfully controlled important physicochemical parameters, such as oxidation state, number of oxygen defects, crystallite size, and the strength of the copper-zinc interaction. It was demonstrated that the H2/CO production ratio (syngas composition) can be tuned by applying in situ potential cycling treatments before the electrochemical measurements under the reaction conditions. For an applied potential of -1.0 VRHE, the H2/CO ratio values of 2.5, 5, and 0.7 were obtained using the same catalyst subjected to different post-synthesis procedures.

Summary: In this study, mixed matrix hollow fiber polymeric membranes were prepared using polyethersulfone (PES) and polyvinylidene fluoride (PVDF) as polymers. The effects of different polymer ratios on membrane performance and physical properties were assessed. The presence of PVDF had a negative effect on the overall mechanical properties of the composite membranes, but increased their plasticity. Scanning electron microscopy (SEM) showed good dispersion of both polymers in the polymeric matrix. The membrane permeability was slightly negatively correlated with contact angle, indicating the importance of membrane hydrophilicity in permeability.

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.
