“…Despite few studies involving TiO 2 disinfection capacity in ceramic substrates, its incorporation into the porous ceramic disk filter and Montmorillonite revealed optimal interaction with E. coli and Staphylococcus aureus , promoting a significant sterilization rate [ 166 , 167 ]. Specific studies [ 168 ] compared the effect of TiO 2 and TiO 2 particles coated in a ceramic plate on the surface antigen of the Hepatitis B virus (HBsAg).…”

The application of TiO2 as a slurry catalyst for the degradation of contaminants of emerging concern (CEC) in liquid effluents has some drawbacks due to the difficulties in the catalyst reutilization. Thus, sophisticated and expensive separation methods are required after the reaction step. Alternatively, several types of materials have been used to support powder catalysts, so that fixed or fluidized bed reactors may be used. In this context, the objective of this work is to systematize and analyze the results of research inherent to the application of ceramic materials as support of TiO2 in the photocatalytic CEC removal from liquid effluents. Firstly, an overview is given about the treatment processes able to degrade CEC. In particular, the photocatalysts supported in ceramic materials are analyzed, namely the immobilization techniques applied to support TiO2 in these materials. Finally, a critical review of the literature dedicated to photocatalysis with supported TiO2 is presented, where the performance of the catalyst is considered as well as the main drivers and barriers for implementing this process. A focal point in the future is to investigate the possibility of depurating effluents and promote water reuse in safe conditions, and the supported TiO2 in ceramic materials may play a role in this scope.

“…A smaller absolute difference value indicates a better imaging accuracy. Factorial effects in a mix-level factorial design can be estimated using a multiple regression model (Jiang et al, 2017;Song et al, 2018;Liu et al, 2020;Zhao et al, 2020). The regression model for the experimental design that contains 12 groups of observed data can be expressed as:…”

In this study, an integrated near-field GPR system (INFGPRs) with a frequency tunable patch antenna was developed to investigate wormholes in oil sand that emerge during CHOPS. 3-dimension imaging of wormholes was then obtained based on INFGPRs through step-scanning against the wall of inspection wells. The feasibility and availability of the developed GPR system were identified through bench-scale simulation in the lab. In addition, a factorial factor experiment was designed in order to reveal the interaction effects of impact factors (depth, size, and content of wormhole) on the performance of the developed GPR system.

“…In Finland, the legislation does not require the removal of anthropogenic substances from wastewater before discharge into the environment and most of the treated wastewaters are discharged to the receiving waters without disinfection. The Water Framework Directive (WFD) [8] aimed to improve the status of all European Water 2021, 13, 360 2 of 11 Union (EU) inland waters, coastal waters, and groundwater by 2015. The deadline has been extended until 2027 at the latest under the WFD derogation rules.…”

“…For example in Mexico, Mejía-Morales et al studied a post treatment with advanced oxidation process (AOP) based on an ultraviolet (UV)/H 2 O 2 /O 3 system in hospital wastewaters [11]. In addition, various other methods have been tested to remove inorganic and organic impurities from water such as porous ceramic disk filter (PVDF) ultrafiltration membrane [12] and porous ceramic disk filter coated with Fe/TiO2 nano-composites [13].…”

Anthropogenic substances are a major concern due to their potential harmful effects towards aquatic ecosystems. Because wastewater treatment plants (WWTPs) are not designed to remove these substances from wastewater, a part of the anthropogenic substances enter nature via WWTP discharges. During the spring 2019, the occurrence of anthropogenic substances in the municipal wastewater effluent in Kuopio, Finland, was analysed. Furthermore, the capacity of selected disinfection methods to reduce these substances from wastewater was tested. The disinfection methods were ozonation (760 mL min−1) with an OxTube hermetic dissolution method (1), the combined usage of peracetic acid (PAA) (<5 mg L−1) and ultraviolet (UV) disinfection (12 mJ/cm2) (2), and the combined usage of hydrogen peroxide (H2O2) (<10 mg L−1) and UV disinfection (12 mJ/cm2) (3). The substances found at the concentrations over 1 µg L−1 in effluent (N = 3) were cetirizine (5.2 ± 1.3 µg L−1), benzotriazole (BZT) (2.1 ± 0.98 µg L−1), hydrochlorothiazide (1.7 ± 0.2 µg L−1), furosemide (1.6 ± 0.2 µg L−1), lamotrigine (1.5 ± 0.06 µg L−1), diclofenac (DCF) (1.4 ± 0.2 µg L−1), venlafaxine (1.0 ± 0.13 µg L−1) and losartan (0.9 ± 0.2 µg L−1). The reduction (%) with different methods (1, 2, 3) were: cetirizine (99.9, 5.0, NR = no removal), benzotriazole (67.9, NR, NR), hydrochlorothiazide (91.1, 5.9, NR), furosemide (99.7, 5.9, NR), lamotrigine (46.4, NR, 6.7), diclofenac (99.7, 7.1, 16.7), venlafaxine (91.3, NR, 1.1), losartan (99.6, 13.8, NR). Further research concerning the tested disinfection methods is needed in order to fully elucidate their potential for removing anthropogenic substances from purified wastewater.
