MW can selectively deliver energy to catalysts, generating localized hot spots and promoting interfacial electron transfer that enhance radical generation and oxidation kinetics. This work demonstrates an energy-dissipation-guided catalyst design for MW-assisted Fenton-like water treatment at a commercially relevant frequency of 2.45 GHz. Catalyst electronic energy dissipation, with conduction loss as a key component, was suggested to be a governing factor in reaction performance. CuO_x (CuO/Cu₂O) nanoparticles were immobilized on porous silica to promote conduction-loss-dominated MW energy dissipation. Structural stability was improved by suppressing aggregation and strengthening copper-silica interactions. Pore-size tuning showed that smaller pores further reduced Cu leaching. This trend is consistent with stronger anchoring of CuO_x via surface -OH and -NH₂ interactions near pore walls. The optimized catalyst (MSN-N1-Cu2%) achieved high degradation performance at neutral pH with only 2 wt% Cu and exhibited ultra-low Cu leaching in each cycle (≤0.028 mg/L) with stable operation over repeated cycles. It further showed broad applicability, completely removing eight representative organic pollutants (aromatic compounds, synthetic dyes, and an organophosphorus compound) within 4 min. In addition, the recalcitrant contaminants PFOA and PFOS exhibited removal efficiencies of 30% and 62%, respectively, within 10 min. These results provide practical guidance for energy-efficient MW-based water treatment and motivate frequency-catalyst matching to direct MW energy toward catalytic activation rather than bulk solution heating.</p>","PeriodicalId":17528,"journal":{"name":"Journal of water process engineering","volume":"92 ","pages":""},"PeriodicalIF":6.6,"publicationDate":"2026-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13649330/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149137385","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study employs a two-step hydrothermal synthesis to design a Co₃O₄@MnO₂/Ti catalyst featuring a unique nano-flower structure. This structure significantly increases electrochemical active sites and enhances charge transfer, thereby driving a remarkable improvement in CER performance. During secondary hydrothermal treatment and calcination, electrons transfer from Co²⁺ to Mn⁴⁺ (Co²⁺ + Mn⁴⁺ → Co³⁺ + Mn³⁺). Co₃O₄ incorporation promotes oxygen vacancy formation, and the synergistic interaction between Co³⁺ and Mn³⁺ dual active sites modulates the local electronic structure, effectively suppressing competitive OER and significantly improving CER selectivity. With a specific surface area of 109.9 m²/g and a charge transfer resistance reduced to 1.47 Ω, Co₃O₄@MnO₂ catalyst not only achieves an impressive current efficiency of 92.5% in neutral 0.6 M sodium chloride solution—over 200% higher than conventional MnO₂ (current efficiency of 28.3%) — but also demonstrates a 30% enhancement in ammonia nitrogen degradation efficiency. Furthermore, it also exhibits superior performance compared to Co₃O₄. These significant innovations and distinctive features provide valuable guidance for optimizing composite material designs.</div></div>","PeriodicalId":17528,"journal":{"name":"Journal of water process engineering","volume":"83 ","pages":"Article 109563"},"PeriodicalIF":6.7,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146080802","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study develops a field-deployable, real-time LSI prediction framework using only three low-cost, continuously measurable sensor inputs: pH, temperature, and electrical conductivity (EC). A 25-year (1991–2015) hydrological dataset comprising 4,633 samples from Khuzestan Province, Iran, was used to train and compare seven optimized models—classical machine learning (GA-tuned SVR, RF, XGBoost), deep learning sequence models (Bayesian-tuned CNN, LSTM, GRU), and a novel hybrid Wavelet-Artificial Neural Network (WANN). Models were evaluated across seven input combinations, with performance assessed via RMSE, MAE, NSE, R², distributional tests (Kolmogorov–Smirnov), rank correlations (Kendall's τ), bootstrapped 99% confidence intervals, and feature importance analysis. The full three-input scenario (EC + pH + Temp) yielded the highest accuracy, with GA-XGBoost (NSE = 0.844, RMSE = 0.132) and Bayesian-WANN (NSE = 0.838, RMSE = 0.134) outperforming deep learning models. Random Forest-based feature importance revealed pH as the dominant driver (58.8%), followed by EC (29.6%) and temperature (11.5%), explaining the modest NSE gain from including temperature. Bootstrap hypothesis testing confirmed statistical equivalence among top performers (GA-XGBoost, GA-SVR, GA-RF, B-WANN). The EC + pH pairing proved a robust alternative (NSE ≈ 0.79–0.80) when temperature data are unavailable. By enabling proactive, sensor-driven scaling risk assessment on lightweight edge devices, this framework overcomes limitations of conventional equilibrium-based indices, offering a practical tool for clogging prevention and sustainable water management in resource-constrained agriculture.</div></div>","PeriodicalId":17528,"journal":{"name":"Journal of water process engineering","volume":"83 ","pages":"Article 109478"},"PeriodicalIF":6.7,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146080896","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A comparative analysis of six mainstream methodologies, focusing on accounting boundaries and emission factors, was conducted. The case calculations for three wastewater treatment plants in northern China indicate significant discrepancies in carbon emission estimates between different methods, with a range of 61% and a standard deviation of 17.35%. An improved accounting method was proposed, integrating operational and extended responsibility emissions, localized emission factors, and simplified procedures. The carbon emission intensity ranged from 0.78 to 1.02 kg CO₂-eq/m³, with electricity consumption, sodium hypochlorite usage, and nitrous oxide emissions as major contributors. Sensitivity analysis showed strong correlations between carbon intensity and nitrogen removal. Each additional 1 mg/L of nitrogen removed increased carbon intensity by approximately 0.014 kg CO₂-eq/m³. A ridge regression model confirmed total nitrogen and biochemical oxygen demand removal as key drivers. Furthermore, a support vector regression model using influent quality parameters achieved robust prediction performance with coefficient of determination values of 0.759, supporting feedforward carbon management for small- and medium-sized plants.
