The results showed that the FEP tubing was a more efficient UV transmitter than quartz glass. The efficiency of the reactor was also affected by the flow rate and pH of the solution. The highest degradation efficiency was achieved at a flow rate of 10 mL/min and a pH of 7.0. The use of TiO₂ as a catalyst also significantly improved the degradation efficiency, with an almost doubling of the degradation rate when compared to the case without a catalyst.

Mahabad Dam, located in the northwest of Iran and recognized as one of the nation’s key dams, served as a case study. First, artificial neural networks (ANN) and support vector regression (SVR) were employed to predict dam inflows, with optimization of parameters achieved through Harris hawks optimization (HHO), a robust optimization technique. The data of temperature, precipitation, and dam inflow over a 24-year period on a monthly basis, incorporating various lag times, were used to train these machines. Then, HEPP from the dam was predicted using temperature, precipitation, dam inflow, and dam evaporation as input variables. The models were applied to data covering the years 2000 to 2020. The results of the first part indicated both hybrid models (HHO-ANFIS and HHO-SVR) improved the prediction performance compared to the single models. Based on the results of Taylor’s diagram and the error evaluation criteria, the HHO-ANFIS hybrid model (RMSE, MAE, and NSE of 3.90, 2.41, and 0.86, respectively) exerted better performance than HHO-SVR (RMSE, MAE, and NSE of 4.39, 2.70, and 0.86, respectively).

The results of Taylor’s diagram also showed that the HHO-ANFIS model exerted better performance.

Research articles addressing the treatment and management of AMD were retrieved from the Scopus database, using specific search criteria. The Scopus Analyze Tool and VOSviewer were used to analyze the publications to provide information on the publication distribution, countries of publication, authorship, keywords, field of study, and author affiliations, while the narrative review provides an overview of how AMD treatment technologies have evolved over these years. The top ten most published countries are developed countries except for South Africa (ranking number 4). This review revealed that several approaches have been developed for AMD treatment and management. It was observed that AMD treatment methods have not drastically changed over the years. Instead, earlier treatment techniques are being improved to develop new and more effective ones. The most recent remediation approach involves the valorization of AMD for the recovery of new materials in economically viable amounts. This is a sustainable approach to AMD treatment; however, it comes with challenges that can be overcome through more research in this area.</p></div>","PeriodicalId":8374,"journal":{"name":"Applied Water Science","volume":"14 9","pages":""},"PeriodicalIF":5.7,"publicationDate":"2024-08-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s13201-024-02259-3.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141994590","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
