The EC experiments were performed in a cylindrical open reactor with 500 mL of effluent, and a fixed current density of 8 mA\/cm\u00b2 was applied through mixed metal oxide electrodes. The experiments were conducted in different sets. In the first round (Set 1), the effluent sample was spiked with three CECs (200 ppb each): caffeine (CAF), carbamazepine (CBZ), and oxybenzone (OXY). For the best treatment period, 6 h, electrodegradation rates ranged from 41 \u00b1 7% for CAF to 95 \u00b1 6% for OXY, with an 87% removal of total culturable microorganisms. In the second round (Set 2), aiming to assess EC process efficiency in a more complex CEC mixture, the effluent was spiked with six more CECs (200 ppb each): diclofenac (DCF), triclosan (TCS), bisphenol A (BPA), 17\u03b2-estradiol (E2), 17\u03b1-ethinylestradiol (EE2), and ibuprofen (IBU), giving a total of nine CECs. In this case, the EC process allowed decreasing the CEC content by 19\u2013100% (below the limit of detection), depending on the effluent samples, and the culturable microorganisms by 99.98% after a 6 h treatment. By contributing to CEC degradation and microorganism removal, the EC process proved to be a viable remediation and disinfection technology for secondary effluent from wastewater treatment plants.<\/jats:p>","DOI":"10.3390\/w13040520","type":"journal-article","created":{"date-parts":[[2021,2,17]],"date-time":"2021-02-17T21:35:42Z","timestamp":1613597742000},"page":"520","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Electrochemical Treatment of Effluent for the Removal of Contaminants of Emergent Concern and Culturable Microorganisms"],"prefix":"10.3390","volume":"13","author":[{"given":"Joana","family":"Dion\u00edsio","sequence":"first","affiliation":[{"name":"CENSE\u2014Center for Environmental and Sustainability Research, Department of Environmental Sciences and Engineering, NOVA School of Science and Technology, NOVA University Lisbon, 2829-516 Caparica, Portugal"}]},{"given":"Cristiana","family":"Gon\u00e7alves","sequence":"additional","affiliation":[{"name":"CENSE\u2014Center for Environmental and Sustainability Research, Department of Environmental Sciences and Engineering, NOVA School of Science and Technology, NOVA University Lisbon, 2829-516 Caparica, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5853-0192","authenticated-orcid":false,"given":"Paula","family":"Guedes","sequence":"additional","affiliation":[{"name":"CENSE\u2014Center for Environmental and Sustainability Research, Department of Environmental Sciences and Engineering, NOVA School of Science and Technology, NOVA University Lisbon, 2829-516 Caparica, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5606-3591","authenticated-orcid":false,"given":"Alexandra","family":"Ribeiro","sequence":"additional","affiliation":[{"name":"CENSE\u2014Center for Environmental and Sustainability Research, Department of Environmental Sciences and Engineering, NOVA School of Science and Technology, NOVA University Lisbon, 2829-516 Caparica, Portugal"}]},{"given":"Nazar\u00e9","family":"Couto","sequence":"additional","affiliation":[{"name":"CENSE\u2014Center for Environmental and Sustainability Research, Department of Environmental Sciences and Engineering, NOVA School of Science and Technology, NOVA University Lisbon, 2829-516 Caparica, Portugal"}]}],"member":"1968","published-online":{"date-parts":[[2021,2,17]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"32","DOI":"10.1016\/j.scitotenv.2019.01.206","article-title":"Removal of Contaminants of Emerging Concern from Urban Wastewater in Novel Algal-Bacterial Photobioreactors","volume":"662","author":"Posadas","year":"2019","journal-title":"Sci.
