Bayesian nonlinear regression was used to quantify uncertainty in both adsorption isotherms and derived thermodynamic parameters. The biochar was characterized by yield, point of zero charge, scanning electron microscopy with energy-dispersive X-ray spectroscopy, Fourier-transform infrared spectroscopy, X-ray diffraction, and N<sub>2</sub> adsorption-desorption isotherms. The experimental data were statistically interpreted using the pseudo-second-order, modified intraparticle diffusion, and Langmuir isotherm model. The results showed that the non-porous structure of CN400 had a smaller surface area than that of CN600 (4 vs. 372 m<sup>2</sup> g<sup>−1</sup>, respectively). However, CN400 exhibited a higher sorption capacity (9.44 vs. 3.48 mmol kg<sup>−1</sup>) at pH 7 and 20 °C, and significantly faster sorption kinetics than CN600 (2 vs. 87 min, respectively). Based on frontier molecular orbital theory calculations, TMP sorption onto CN400 was driven by three synergistic mechanisms including electrostatic attraction, hydrogen bonding, and π–π electron donor–acceptor interactions. Interestingly, raising the temperature from 20 to 32 °C resulted in a 1.8-fold increase in <em>Q</em><sub>max</sub> for CN400 and up to a 6.9-fold increase for CN600, attributed to enhanced pore diffusion kinetics at high solution temperatures. Bayesian inference-based thermodynamic analysis confirmed that the TMP sorption process was both spontaneous and exothermic. Our statistical findings suggest that tailoring CN400/CN600 biochar could offer a synergistic strategy to accelerate TMP adsorption and maximize sorption capacity in water treatment systems.</div></div>","PeriodicalId":34388,"journal":{"name":"Case Studies in Chemical and Environmental Engineering","volume":"12 ","pages":"Article 101264"},"PeriodicalIF":0.0,"publicationDate":"2025-07-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144680199","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The demand for power is rising as a result of the ongoing population growth and the desire to develop these isolated locations. However, the adoption of renewable energy sources increased as a result of the scarcity of fossil fuels in these isolated places and the expensive cost of grid extensions. To develop these isolated desert locations, a hybrid renewable energy system (HRES) consisting of a diesel generator (DG), battery (B), wind turbine (WT), and solar panel (PV) is proposed. Battery storage and diesel generators operate as backup supplies in a stand-alone system, working in combination with other hybrid renewable energy system components. The expected electricity demands for ten dwellings in a small rural community in Hafar Al Batin, Saudi Arabia, are provided by this system. The seasonal and daily load curves of the suggested community are assessed. This community needs an electrical load of 53 kW. The optimal hybrid energy system combination for the proposed site is determined using HOMER Software, harmonizing reliability, cost, and minimal use of DG sets. The simulation results indicate that, despite the significant potential of wind and solar energies at the selected site, it was not adequate for an independent wind turbine system and a PV system. Thus, a storage battery or another form of energy conversion, like a diesel generator, is required. The results demonstrated that the cost of energy (COE) produced by the optimal hybrid WT/PV/DG/B system is 0.213 $/kWh. The ideal system comprises 20 kW PV panels, 330 kW WT, 58 kW DG, and 158 batteries, which can meet the electric load. The net present cost (NPC) of this optimal system is $ 628,571. Including a storage capacity is essential in order to minimize how often the DG operates and the number of hours it runs.</div></div>","PeriodicalId":34388,"journal":{"name":"Case Studies in Chemical and Environmental Engineering","volume":"12 ","pages":"Article 101257"},"PeriodicalIF":0.0,"publicationDate":"2025-07-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144631992","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
