Summary: In this study, a completely novel approach of hybridizing electro-peroxone (EP) with a sacrificial iron anode (EP/iron) was investigated for the degradation of ciprofloxacin (CIP). The EP/iron process exhibited superior degradation performance compared to other methods tested, completely degrading CIP in 40 minutes with a rate constant of 0.126 min-1 under optimal conditions. Operational parameters and inhibitory effects of naturally-occurring anions were thoroughly evaluated, and the EP/iron process showed excellent potential for the removal of CIP and total organic carbon (TOC) content in real hospital wastewater.

Summary: Chlorobenzene, a typical toxic and persistent organic pollutant, was successfully adsorbed by powdered activated carbon (AC) from simulated wastewater. The adsorption capacity of AC was high and unaffected by pH. The adsorption process was described by the pseudo-second-order kinetic model and Langmuir isothermal adsorption model. The adsorption mechanism was clarified by correlating the adsorption rate constants with molecular descriptors. Ozonation was effective in regenerating the saturated AC and increasing its adsorption capacity.

Summary: In this study, the oxygen-doped carbon nanotubes coated on the carbon felt were used as cathode to enhance the electro-peroxone (OCNT-EP) process. The modified cathode achieved in-situ H2O2 generation, activation, and catalytic ozonation, resulting in a higher degradation rate and wider pH application range compared to the traditional EP process. The OCNT-EP process showed promising potential for wastewater treatment.

Summary: The electro-peroxone (EP) process is an electricity-based oxidation process that generates hydrogen peroxide (H2O2) from cathodic oxygen (O2) reduction to remove antibiotic resistant bacteria (ARB) and plasmid-encoded antibiotic resistance genes (ARGs). Compared to ozonation alone, the EP process exhibits higher center dot OH exposures but lower O3 exposures, resulting in a moderately decreased efficiency of ARB inactivation and ARG degradation. However, the EP process effectively cleaves plasmid DNA to shorter fragments, reducing the risks of natural transformation of ARGs. Consideration of the effects of the EP process on ARB and ARG inactivation is important for water treatment implementation.

Summary: The study found that the degradation and mineralization of ofloxacin by ozonation and peroxone process were effective, with peroxone process showing a significantly better mineralization effect compared to ozonation alone. The dosage of H2O2 and O-3 was crucial for process performance, and the presence of HCO3- and PO43- enhanced mineralization while Cl- and NO3- had a negative impact on mineralization efficiency.

Summary: In this study, the long-term performance of the GAC particle electrode oxidation process (GAC EOP) on amoxicillin (AMX) removal and activated carbon regeneration was investigated. The results showed that the GAC electrode had a more stable physisorption and chemisorption capacity compared to the GAC adsorption process (GAC ADS). The electrochemical regeneration effect ensured the stable chemisorption capacity of the GAC EOP system, resulting in a continuous increase in AMX removal efficiency during the 50 consecutive runs.

Summary: The production of plastic has significantly increased over the past decades, leading to the emergence of microplastics and nanoplastics, which pose potential risks to the environment and human health. Recent evidence suggests an increasing trend in microplastic concentration, with laboratory studies showing exposure levels much higher than those found in the environment. Microplastics have also been detected in feces, indicating possible excretion from animals and humans. Current studies have uncertainties, emphasizing the need for policies to reduce microplastic emissions and overcome technical obstacles in detection.

Summary: Electrochemically producing hydrogen peroxide (H2O2) from oxygen reduction reaction (ORR) with natural air diffusion electrode (NADE) is an attractive way for decentralized water treatment. However, the presence of calcium ions (Ca2+) in water matrices can cause significant deterioration of NADE stability during H2O2 electroproduction, leading to reduced current efficiencies. Proper strategies are needed to mitigate electrode fouling during H2O2 electroproduction in practical water and wastewater treatment.

Summary: A probe compound-based kinetic model was developed to predict micropollutant (MP) abatement in various water matrices by the UV/chlorine process. This model allows for the calculation of the exposures of reactive chlorine species and hydroxyl radicals during the process based on the depletion of three probe compounds. The model can predict the abatement efficiencies of different MPs in different water matrices without prior calibration and provides insights into the abatement mechanism of MPs during UV/chlorine treatment.

Summary: Superoxide radicals (O-2(center dot-)) are important chain carriers in the radical chain reaction during ozonation, promoting the decomposition of ozone (O-3) to hydroxyl radicals ((OH)-O-center dot). This study used a probe compound and kinetic modeling to evaluate the role of O-2(center dot-) for O-3 decomposition during ozonation of synthetic solutions and natural waters. The results showed that O-2(center dot-) plays a critical role in promoting O-3 decomposition, with its contribution ranging from 45-70% depending on water composition.

Summary: The paper proposes a novel deep learning-based prediction framework, aTCN-LSTM, for accurate cooling load predictions. The framework utilizes a gate-controlled multi-head temporal convolutional network and a sparse probabilistic self-attention mechanism with a bidirectional long short-term memory network to capture both temporal and long-term dependencies in the cooling load sequences. Experimental results demonstrate the effectiveness and superiority of the proposed method, which can serve as an effective guide for HVAC chiller scheduling and demand management initiatives.
