Summary: This study aims to optimize a two-step treatment for mature landfill leachate using electrocoagulation (EC) followed by Fenton or UVA-LED photo-Fenton processes, in order to provide a more efficient and feasible treatment strategy that increases biodegradability and decreases conductivity. The research found that higher EC current density results in higher residual iron concentration, which can reduce treatment time for subsequent Fenton processes. Overall, the total COD removal rate was around 87%, with improvements in SUVA removal, conductivity reduction, and biodegradability.

Summary: Combining ozonation and microfiltration as pretreatments for reverse osmosis in treating landfill leachate can significantly reduce fouling potential and meet discharge standards. Conducting ozonation before microfiltration results in lower fouling index values and higher permeate flux compared to the reverse order.

Summary: This study used response surface methodology (RSM) to determine the optimal operating conditions of the Fenton process as a pre-treatment for landfill leachate (LL). The aim was to reduce the organic content and optimize the BOD5:TN:TP ratio. The variables Fe2+ and H2O2 concentrations significantly affected the responses, with oxidation mechanisms dominating over coagulation. The optimal conditions were Fe2+ concentration of 4262 mg/L, H2O2 concentration of 5104 mg/L (H2O2/Fe2+ molar ratio = 2), with COD, BOD5, TN, and TP removals of 70%, 67%, 84%, and 96% respectively, and improved BOD5:TN:TP ratio of 100:6:1. Furthermore, this approach minimized sludge formation and provided a useful tool for LL pre-treatment.

Summary: This article presents a model for predicting the degradation of in-service railway bridges. The model is based on a semi-Markov continuous time process and uses the inspection history of 588 bridges on a heavy-haul railway line in Brazil between 2016 and 2020. A computational tool developed in Matlab enables automated data processing. A parametric study is conducted to identify the most influential factors in the deterioration model, including bridge structural characteristics, operational factors, and environmental factors. Specific prediction models are established for concrete bridges and steel bridges. The prediction models achieve an efficiency of 93.7% for concrete bridges and 95.1% for steel bridges. The analysis of preventive and corrective maintenance scenarios optimizes the condition ratings throughout the life cycle, particularly for concrete bridges.
