Leachate treatment is essentially carried out trough biological and physicochemical processes, which have showed variability in efficiency and appear a costly solution for the management authorities. Electrocoagulation (EC) seems a suitable solution for leachate treatment taking into account the characteristics of the liquor. One of the problems of EC is the electrode passivation, which affects the longevity of the process. One solution to this problem could be the replacement of the electrode by one made of recyclable material, which would make it possible to change it frequently and at a lower cost. The objective of the present work was to evaluate the removal of heavy metals (As, Ba, Cd, Cr, Cu, Fe, Pb, Mn, Ni, Se and Zn) and coliforms from a LL by EC using electrodes made from steel swarf (SfE) up to 8 h. Removal efficiencies of detected heavy metals were 51%(Cr), 59%(As), 71%(Cd), 72%(Zn), 92%(Ba), 95%(Ni) and &gt;99%(Pb). The microbial load of coliforms in leachate was reduced from 10.76 \u00d7 104 CFU\/mL (raw leachate) to less than 1 CFU\/mL (after treatment with SfE) (i.e., approximately 100% reduction). The use of SfE in EC of LL is very effective in removing heavy metals and coliforms and can be used as alternative treatment solution for such effluents.<\/jats:p>","DOI":"10.3390\/app11115009","type":"journal-article","created":{"date-parts":[[2021,5,28]],"date-time":"2021-05-28T11:33:20Z","timestamp":1622201600000},"page":"5009","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":9,"title":["Application of Electrocoagulation with a New Steel-Swarf-Based Electrode for the Removal of Heavy Metals and Total Coliforms from Sanitary Landfill Leachate"],"prefix":"10.3390","volume":"11","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-8094-3804","authenticated-orcid":false,"given":"Mayk Teles","family":"de Oliveira","sequence":"first","affiliation":[{"name":"Faculty of Pharmacy, Federal University of Goi\u00e1s, Goi\u00e2nia 74605-170, Brazil"}]},{"given":"Ieda Maria Sapateiro","family":"Torres","sequence":"additional","affiliation":[{"name":"Faculty of Pharmacy, Federal University of Goi\u00e1s, Goi\u00e2nia 74605-170, Brazil"}]},{"given":"Humberto","family":"Ruggeri","sequence":"additional","affiliation":[{"name":"School of Civil and Environmental Engineering, Federal University of Goi\u00e1s, Goi\u00e2nia 74605-170, Brazil"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0833-7826","authenticated-orcid":false,"given":"Paulo","family":"Scalize","sequence":"additional","affiliation":[{"name":"School of Civil and Environmental Engineering, Federal University of Goi\u00e1s, Goi\u00e2nia 74605-170, Brazil"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7099-0685","authenticated-orcid":false,"given":"Antonio","family":"Albuquerque","sequence":"additional","affiliation":[{"name":"Department of Civil Engineering and Architecture, FibEnTech, GeoBioTec, University of Beira Interior, 6200-358 Covilh\u00e3, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9161-0127","authenticated-orcid":false,"given":"Eric de Souza","family":"Gil","sequence":"additional","affiliation":[{"name":"Faculty of Pharmacy, Federal University of Goi\u00e1s, Goi\u00e2nia 74605-170, Brazil"}]}],"member":"1968","published-online":{"date-parts":[[2021,5,28]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Fernandes, A., Cir\u00edaco, L., Pacheco, M.J., Lopes, A., and Albuquerque, A.
