Experiments with the fixed-bed and fluidized-bed reactors were consecutively repeated 10 times to demonstrate the durability of the 1.1 % Fe-2.7 % Ce/GAC catalysts. This study compared fixed-bed and fluidized-bed reactors in the three-dimensional electrocatalytic oxidation of high-concentration phenol for the first time. The fluidized-bed demonstrated faster phenol removal, establishing it as a preferred option for scaling phenolic wastewater treatment systems.</div></div>","PeriodicalId":17528,"journal":{"name":"Journal of water process engineering","volume":"75 ","pages":"Article 107874"},"PeriodicalIF":6.3,"publicationDate":"2025-05-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143931934","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}
