Summary: The complexity and dynamic characteristics of landfill leachate pose challenges for its treatment. A combined treatment process, including a one-stage partial nitrification-Anammox process, an O-3/H2O2 process, and a granular activated carbon filtration (GAC) process, was investigated. A surrogate-based ozone dose control strategy for the O-3/H2O2 process was evaluated. Results showed that this three-stage process achieved high removal rates of total nitrogen, COD, and micropollutants, satisfying discharge requirements. Real-time control of ozone dosing for COD removal was achieved through monitoring UVA(254) reduction. Cost analysis indicated that the combination of O-3/H2O2 and GAC as the main steps was more cost-effective in post-treatment. A dynamic operation strategy in response to leachate changes was recommended.

Summary: This study focuses on the 4th treatment step in Degeberga WWTP, which uses a full scale GAC filter for the removal of micropollutants. The results show that the sand filter provides effective protection to the carbon filters and biodegradation plays a role in the removal of some micropollutants. The average removal of 24 compounds over three years is 89% in the 4th treatment step. The study suggests that the combination of sand and GAC filters in WWTPs is promising for removing organic micropollutants.

Summary: A novel process involving simultaneous electrochemical oxidation and electrosynthesis of permanganate oxidant was explored for treatment of triazine herbicide atrazine. Permanganate synthesis was largely unaffected by the operating current density, and hydroxyl radical mediated oxidation was observed to degrade atrazine with or without enhanced oxidation by permanganate generation. This process yielded second-order reaction rate constants for atrazine degradation with electrochemically generated permanganate and dosed potassium permanganate.

Summary: Electrochemical interfaces are ensembles of varying electrons. Simulating them with first-principles methods is challenging as the number of electrons is fixed. We developed a constant potential simulation method by adding an adaptive electric field, with the electric field as the controlling variable. We also defined an internal reversible hydrogen electrode potential to ensure the model independence of our method. By calculating reaction energies and discussing transition state structures and charge transfer coefficients, we validated our method.

Summary: This paper focuses on evaluating the mobility of four hexachlorocyclohexane (HCH) isomers using soil vapor extraction (SVE) combined with direct electrokinetic (EK) treatment. The results showed that SVE was highly efficient, removing nearly 70% of the four HCH isomers in the 15-day tests. Electrokinetics facilitated the transport of HCH to the cathode through various electrochemical processes, which were accurately modeled using a 1-D transport equation. Increasing the electric field resulted in enhanced pollutant transport, although 15 days was insufficient for efficient transportation of pollutants towards the cathode. The loss of water content near the cathode highlighted the need for electrokinetic flushing technologies instead of simple direct electrokinetics. Overall, no significant differences were observed in the removal of the four HCH isomers between SVE and EK processes.

Summary: In this study, a novel 3D printed casing was designed and manufactured for PEM electro-ozonizers to enhance fluid dynamics and reduce ozone-scavenger interactions during electrolysis. It was found that electrogenerated scavengers, particularly cathodically formed hydrogen peroxide, limit the efficiency of electrochemical ozone production. The effects of current density, electrolyte composition, and operation pressure on efficiency were explored, with higher efficiencies achieved at higher current densities, lower concentrations of non-reacting electrolytes, and lower operation pressures. The 3D printed casing demonstrated excellent performance with ozone productions as high as 0.240 mg/(Ah cm2) and maximum current efficiencies of 5.9% under optimal conditions, showcasing the potential of 3D printing in improving electrochemical processes.

Summary: This study evaluates the electrosynthesis of hydrogen peroxide from the oxygen reduction reaction using a flow-by electrochemical cell under different operation conditions and electrodes. A phenomenological model is proposed to understand the processes inside the electrochemical reactor and the influence of predatory species on H2O2 production at high concentrations. Comparing different anodes, DSA-Cl2 is found to be twice as efficient as BDD, allowing for concentrations as high as 4.2 g L-1. The decomposition of H2O2 is influenced by the electrochemical processes of predatory species such as ozone and peroxymonopersulfate.

Summary: The study evaluates and validates the electrokinetic transport of pollutants from polluted to clean soil at different temperatures using a simple transport model. Real samples contaminated with residues from lindane production are utilized. The results show negligible dragging of aged pollutants, low electro-osmotic fluxes, and insignificant pollutant accumulation in electrolyte wells. However, there is significant volatilization of chlorinated organic compounds (COCs), which accumulate in the mockup walls and pipes. The results align well with a 1-D non-reactive model, and the diffusion coefficients of COCs are independent of chlorine substitutions.

Summary: This study investigates the degradation of a mixture of pharmaceutics in different types of water matrices through various methods including photolysis, electrolysis, and photo-electrolysis. A new metrological approach is developed to screen pharmaceuticals in waters, allowing for the detection at low concentrations. The results show that the inorganic composition of the water matrix has a direct impact on the efficiency of drug removal, with better degradation observed in experiments with surface water. The most recalcitrant drug studied is ibuprofen, while diclofenac and ketoprofen are found to be the easiest to degrade. Photo-electrolysis is found to be the most efficient method, although it requires higher energy consumption.

Summary: This study evaluates the influence of ultrasound (US) on the absorption and electrochemically assisted absorption of gaseous streams polluted with BTX. The experimental device combines a jet mixer absorber and a single-compartment electrochemical flow cell equipped with a BDD anode. Results show that the application of US has a positive effect on the amount of pollutants absorbed and oxidized, promoting mass transfer processes and activating oxidizing species. Intermediates produced in the oxidative degradation of BTX were mainly carboxylic acids. The removal rate increases with an increase in current density, but the elimination efficiency and the synergy coefficient decrease. A simple model is formulated and applied to satisfactorily reproduce experimental results and aid in understanding the processes involved.

Summary: This study investigates the challenge of providing safe tap water while limiting the occurrence of disinfection by-products (DBPs) in a full-scale drinking water treatment plant. Different technologies, such as aeration, coagulation, hydrogen peroxide dosage, ion exchange, and ultrafiltration, were studied in a real surface water matrix. The results show that agitation aeration is most effective in removing DBPs directly, while ion exchange resin is the best at inhibiting their formation. Hydrogen peroxide dosage also shows promising results in preventing the formation of bromate. This study serves as a reference for selecting optimal treatment technologies in full-scale drinking water treatment plants to limit DBP occurrence.

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.
