There are many ways to design these sedimentation basins, some of which lead to unrealistic results because of their simplifying assumptions. Some of these methods are complex and are extremely difficult to use. Meanwhile, other methods to reduce the above problems have been proposed by a number of researchers that are based on laboratory or analytical studies. Due to the existence of various models, it is difficult to determine which approach is the most appropriate model. Here, by introducing multiple methods, their performance has been evaluated by comparison with laboratory data. Experiments were conducted on a flume 12 m in length, 1.2 m in width, and 0.5 m in height for three sediment sizes and for different discharges. Trapping efficiencies were calculated based on the remaining sediment in the invert of the flume after completion of the experiment. The results showed that the United States bureau of reclamation model shows a high efficiency of the sedimentation basins. In addition, it was found that the efficiency estimates of this model are very sensitive to input parameters. Examination of various statistical characteristics showed that the trapping efficiency in this study is consistent with the Sarikaya and Einstein models. Also, a regression equation with an accuracy of RMS = 7.32 can be used to estimate the trapping efficiency in irrigation sediment basins.</p></div>","PeriodicalId":589,"journal":{"name":"International Journal of Environmental Science and Technology","volume":"20 10","pages":"11301 - 11308"},"PeriodicalIF":3.1,"publicationDate":"2023-08-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s13762-023-05159-2.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"24849774","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"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}

In this condition, the predicted and real values of COD removal percent were 96.20 and 97.0%, respectively. The kinetic analysis showed that the COD removal pursued the first-order kinetic model, and the half-life and reaction rate constant in the kinetic were 14.5 min and 0.0479 min<sup>−1</sup>, respectively. The considered specific energy consumption (SEC) value in the PEF process was 22.71 kWh/m<sup>3</sup> removal, showing that this process could be a cost-effective technique for the remediation of spent caustic effluent on a laboratory works.

The synergistic effect of municipal sludge and blue-green algae enhanced microbial activity through creating a better aerobic composting environment and, therefore, improved the permeability of the input streams.

Between 2000 and 2022, a total of 207 documents involving “pharmaceutical” and “LCA” were released. Numerous aspects of these documents, including subject categories, journals, articles, countries, affiliations, funding sponsors, authors, and keywords, have been systematically examined in this research. Collaborations between authors and countries were visualized and analyzed by using social network analysis based on co-authorship relations. Additionally, keywords were clustered using co-occurrence relations to discover the most trending topics in the literature review. The research showed that as an evolutionary process, the utilization of the life cycle assessment method has continued to increase in the pharmaceutical sector within the period. As well, the principal focus of studies has been on pharmaceuticals for human consumption. The analysis of extracted keywords reveals that green chemistry, energy efficiency, and sustainable pharmacy have always been the main topics.
