Summary: This study successfully removed wastewater containing the insecticide IMI using a fluidized-bed Fenton process, achieving a degradation efficiency of 97% for IMI under specific conditions. Bed expansion did not significantly affect IMI degradation but slightly deteriorated total iron removal performance.

Summary: The fluidized-bed Fenton (FBR-Fenton) process has gained attention for treating industrial wastewater, combining the effectiveness of Fenton synthesis and sludge reduction. Challenges include high consumption of Fenton reagents and strict pH control, but strategies for overcoming these limitations are being discussed for improving cost-effectiveness. Modeling techniques like computational fluid dynamics and artificial neural networks show promise for accelerating the full-scale application of FBR-Fenton technologies.

Summary: The study evaluated the fluidized-bed Fenton (FBF) process as a tertiary treatment for the effluent from an industrial wastewater treatment plant, focusing on the removal of soluble iron using different carriers. The results showed that the pH and molar ratio of [Fe2+][H2O2] were essential variables affecting the performance of the FBF process, with an adaptive pH range of 2.5 to 7.4. However, high pH led to reduced iron removal efficiency due to homogeneous nucleation. Increasing the molar ratio of [Fe2+]/[H2O2] improved removal performances, but excess iron addition had a negative effect. An actual engineering project demonstrated the effectiveness and cost-efficiency of the FBF process for tertiary treatment.

Summary: In this study, the TVDBFB showed higher nitrogen removal efficiency, specific nitrification and denitrification rates compared to the AO process at different temperatures, with a smaller footprint. Factors such as alkalinity/NH4+-N, BOD5/TN, and temperature play important roles in the compliance rate. Increasing the carrier packing rate has emerged as a new strategy for enhancing compliance rate.

Summary: Activated carbon coated on glass beads was used for the adsorption of phenol. Both batch and column adsorption studies were conducted, and kinetic and thermodynamic parameters were evaluated. The results showed that the adsorption process followed pseudo-second-order kinetics and was endothermic and non-spontaneous. The Temkin isotherm model was found to have the best fit, and the system was determined to be physisorption in nature.

Summary: This study evaluated the bioconversion of phenols in biorefinery wastewater using Horseradish peroxidase (HRP) and the Fenton process. The enzymatic treatment achieved a phenol conversion rate of 97.5%, while the Fenton process was used as a complementary method for further phenol removal. The combination of HRP and Fenton proved to be effective in treating biorefinery wastewater and removing phenols.

Summary: This study explored the potential of thermally modified laterite soil as a catalyst in the fluidized bed photo-Fenton process for treating textile wastewater. The results showed that the catalyst significantly reduced the total organic carbon (TOC) content in the wastewater and exhibited high catalytic stability. The fluidized bed photo-Fenton approach has low operating costs and low environmental impact, making it a feasible option for treating wastewater of different colors.

Summary: Advanced oxidation processes (AOPs) are emerging techniques for wastewater treatment, with Fenton-related processes being particularly effective in degrading organic compounds. Conventional Fenton processes have challenges such as sludge generation and high chemical consumption, which can be addressed through mass transfer and process intensification using continuous reactors like fluidized bed and packed bed. This review article discusses the recent applications of packed bed and fluidized bed reactors coupled with Fenton-related processes for synthetic and industrial wastewater treatment, providing useful information and recommendations for further research in this area.

Summary: This study has shown that the Fenton fluidized bed (FFB) technology can successfully immobilize As ions on IC carriers, while also crystallizing ferric and mineralizing organic pollutants. The immobilization of As(V) on the IC carriers occurs rapidly through surface favorable bidentate complexion, while the removal of As(III) through adsorption is slow. The addition of Fe3+ inhibits As(V) immobilization but promotes oxidative crystallization of Fe(II) and As(III). As a result, efficient co-crystallization of As(V)/Fe(III) is achieved.

Summary: This study evaluated and compared the environmental performance of five different technologies for phenolic wastewater treatment. The solar photo-Fenton process was identified as the most environmentally friendly technology, while the electro-Fenton process had the highest impacts. Economic analysis showed that the adsorption process was the most affordable, while electro-Fenton was the costliest process.

Summary: Experiments and simulations were conducted to study the air volume fraction and hold-up in a bubble channel reactor. A new signal processing method was proposed to avoid the loss of bubble residence time. The results were in agreement with previous studies and a bubble-scale model was developed to explain the relationship between hold-up and air superficial velocity.
