These elements prevent the treatment of these effluents, for which all the treatments applied failed to meet the discharge standards. On the other hand, fly ash from thermal power plants is a severe environmental issue worldwide. The valorization of these wastes may be the best strategy to protect our environment. In this respect, the primary purpose of this work is to emphasize a promising technique for OMW treatment, using filtration through fly ash. A physical–chemical and microbiological characterization of the OMW was carried out beforehand. Then, the treatment was performed in the fixed-bed column adsorption process using fly ash as an adsorbent. This characterization revealed that the OMW have an acidic pH and is abundant in organic matter, as illustrated by the BOD₅ (20,650 mg O₂/L) and COD (99,864 mg O₂/L). They are equally characterized by a high concentration of phenolic compounds (6452 mg/L). Microbiological characterization revealed a total absence of pathogenic and fecal germs. The treatment of OMW by fly-ash filtration provided outstanding results as illustrated by the abatement rates obtained, which were 100%, 99.77%, 99.63%, and 99.96%, respectively for discoloration, BOD₅, COD, and polyphenols. In addition, the treated effluent perfectly fulfilled the Moroccan rejection standard. The fly ash support has shown a purifying performance for all toxic loads. Therefore, fly ash filtration could be an appealing and cost-effective technique for the treatment of both highly loaded and poisonous wastewater. Furthermore, fly ash could replace activated carbon in water treatment plants.</p></div>","PeriodicalId":589,"journal":{"name":"International Journal of Environmental Science and Technology","volume":"22 6","pages":"4511 - 4520"},"PeriodicalIF":3.0,"publicationDate":"2024-11-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143465924","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Extensive research is necessary to address these issues and predict future temperature fluctuations in the area. The Middle East is a fragile region that would face critical conditions due to temperature increases and a lack of precipitation in the future. This research aimed to investigate temperature data from 720 network points in the Middle East, taken from the NOAA site at a 1*1 degree resolution. The data was processed using Office-Excel software and assessed using the Mann–Kendall method. The temperature variation was evaluated from 1979 to 2017, and the processed data were classified by Arc GIS software and geostatistical analysis, including kriging. The study showed that approximately 91 percent of the region experienced a significant temperature increase, with an average rise of about 1.32°C over 39 years (1979–2017). This indicates that the warming trend in this region is greater than the total warming of the Earth, and almost half of the region experienced temperature increases ranging from 1 to 2°C. The central areas of Yemen have experienced the highest temperature rise, with increases of more than 5 degrees. As a result, extensive surveys are necessary to determine the causes and consequences of this phenomenon.</p></div>","PeriodicalId":589,"journal":{"name":"International Journal of Environmental Science and Technology","volume":"22 6","pages":"4503 - 4510"},"PeriodicalIF":3.0,"publicationDate":"2024-11-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143465939","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This work focuses on the comparative adsorption evaluation of synthesized biochar derived from green coffee wastes (GCB) and NaOH-modified GCB (NaOH-GCB) for the removal of anionic dyes (Eriochrome Black T and Congo Red) in aqueous solution. The characterization results of NaOH-GCB indicate higher thermal stability, improved surface functionality with -OH groups, smaller particle size (from 2–15 µm decreased to 0.5–1 µm), higher pore volume (increase from 0.0027 to 0.003 cm³/g), and higher surface area (increase from 2.91 to 3.22 m²/g) which enhanced dye adsorption. The maximum adsorption capacity was attained using NaOH-GCB with values of 119.37 mg/g and 91.54 mg/g recorded for EBT and CR, respectively. For both adsorbents, the optimal removal for EBT and CR dyes was obtained at solution pH 2 and 7 due to electrostatic and hydrogen bonding interactions. CR had slightly lower removal than EBT due to its hydrophobic nature. Pseudo-second order and Redlich-Peterson were the most effective models in providing insights about the adsorption kinetics and isotherm, with the system being heterogeneous and involving multi-layer behavior. Additionally, thermodynamics elucidated the adsorption to be spontaneous and exothermic. After five reusability cycles, the NaOH-GCB indicated excellent performance of over 90% removal for both dyes. The results show that NaOH-GCB is potentially an economical adsorbent for efficient and effective remediation of dye-contaminated wastewater streams.</p></div>","PeriodicalId":589,"journal":{"name":"International Journal of Environmental Science and Technology","volume":"22 9","pages":"7721 - 7738"},"PeriodicalIF":3.0,"publicationDate":"2024-11-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143904837","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The use of multi-objective response surface methodology with a desirability function underscores the importance of these findings. Temperature, resin depth and pH were selected as independent factors, while, hardness, concentrations of cations (calcium, magnesium, manganese), conductivity and total dissolved solids were the dependent variables. Individual quadratic regression models were developed for each dependent variable and water sample, yielding high coefficient of determination and low relative error, mean absolute error and mean squared error values. Using a multi-objective optimization approach, optimal values for demineralization were achieved and validated experimentally, showing good agreement between measured and predicted values. Analysis of variance analysis revealed that all independent variables were significant (<i>p</i> &lt; 0.05) and notably affected all responses. The high combined desirability values for both samples indicate that the set of optimal conditions was effective in minimising all responses. The reasonable coefficient of determination for all models, along with the low values of statistical performance indicators suggest that the laboratory test data fit the predicted response values. Both water samples achieved an optimal removal efficiency greater than 95%, with the maximum values of conductivity, cations, and total dissolve solids.

The present study aimed to evaluate the Phosphorus adsorption capacity (q_max) of a residue from the pulp and paper industry, “grits”, which are rich in Calcium. The residues were characterized using diverse techniques, and kinetic and isothermal essays were performed with dried (105 °C) and calcined (650 °C) grits.

Furthermore, calcination increased the specific surface area of the grits (from 1 m to 6.3 m² g^‒1). The pH_pzc for dried grits was 7.25, and for calcined grits 7.97. The kinetic tests revealed an equilibrium time of 12 h for dried grits, and 1 min for calcined grits. The isothermal tests reached maximum adsorption capacities (q_max) of 10.3 and 111.6 mgP g^‒1 for dried and calcined grits, respectively. The calcined grits were shown to be a better adsorption material, leading to faster removal of dissolved P.
