Two synthetic dyes Bemacron Blue RS 01 (BB-RS01), a disperse dye, and Bemacid Marine N-5R (BM-N5R), an acid dye were selected for evaluation. The coagulation\u2013flocculation process utilized aluminum sulfate as the coagulant and Superfloc 8396 as the flocculant, with operational parameters including coagulant concentrations ranging from 50 to 600 mg\/L, flocculant concentrations between 30 and 125 mg\/L, and pH levels spanning from 2 to 11. The corncob biosorbent was characterized using FTIR, SEM, BET, TGA\/DTA, and pHpzc analyses. Adsorption isotherm experiments indicated a more favorable correlation with the Langmuir model (R2 = 0.92\u20130.96), which supports monolayer adsorption. At pH 8, the CFS process achieved a dye removal efficiency of 95.1% for BB-RS01 and 92.3% for BM-N5R was achieved at pH 6.5. The maximum adsorption capacities of BB-RS01 were determined to be 99.5 mg\/g, while BM-N5R was found to be 46.08 mg\/g. These results indicate that the integration of CFS with raw corncob adsorption provides a cost-effective and efficient method for the remediation of textile dyes.<\/jats:p>","DOI":"10.3390\/environments12060201","type":"journal-article","created":{"date-parts":[[2025,6,16]],"date-time":"2025-06-16T05:28:33Z","timestamp":1750051713000},"page":"201","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":11,"title":["Coupling Coagulation\u2013Flocculation\u2013Sedimentation with Adsorption on Biosorbent (Corncob) for the Removal of Textile Dyes from Aqueous Solutions"],"prefix":"10.3390","volume":"12","author":[{"ORCID":"https:\/\/orcid.org\/0009-0000-6611-9627","authenticated-orcid":false,"given":"Hadj Boumedien","family":"Rahmoun","sequence":"first","affiliation":[{"name":"Eau et Ouvrages dans Leur Environnement (EOLE) Laboratory, Department of Hydraulic, Faculty of Technology, University of Tlemcen, Tlemcen 13000, Algeria"}]},{"ORCID":"https:\/\/orcid.org\/0009-0005-9357-5392","authenticated-orcid":false,"given":"Maamar","family":"Boumediene","sequence":"additional","affiliation":[{"name":"Promotion des Ressources Hydriques, Mini\u00e8res et P\u00e9dologiques: L\u00e9gislation de l\u2019Environnement et Choix Technologiques Laboratory, Department of Hydraulic, Faculty of Technology, University of Tlemcen, Tlemcen 13000, Algeria"}]},{"given":"Abderahmane Nekkache","family":"Ghenim","sequence":"additional","affiliation":[{"name":"Eau et Ouvrages dans Leur Environnement (EOLE) Laboratory, Department of Hydraulic, Faculty of Technology, University of Tlemcen, Tlemcen 13000, Algeria"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3019-8471","authenticated-orcid":false,"given":"Eduardo Ferreira","family":"Da Silva","sequence":"additional","affiliation":[{"name":"GeoBioTec Research Unit, Department of Geosciences, Campus de Santiago, University of Aveiro, 3810-193 Aveiro, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4782-1685","authenticated-orcid":false,"given":"Jo\u00e3o","family":"Labrincha","sequence":"additional","affiliation":[{"name":"Associate Laboratory CICECO\u2014Aveiro Institute of Materials, Department of Material Engineering and Ceramics, Campus de Santiago, University of Aveiro, 3810-193 Aveiro, Portugal"}]}],"member":"1968","published-online":{"date-parts":[[2025,6,13]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"785","DOI":"10.1038\/s43017-023-00489-8","article-title":"Environmental impacts and remediation of dye-containing wastewater","volume":"4","author":"Lin","year":"2023","journal-title":"Nat.
