The potential of nitrate electro-bioremediation has been fully demonstrated at the laboratory scale, although it has not yet been fully implemented due to the challenges associated with scaling-up bioelectrochemical reactors and their on-site operation. This study describes the initial start-up and subsequent stable operation of an electro-bioremediation pilot plant for the treatment of nitrate-contaminated groundwater on-site (Navata site, Spain). The pilot plant was operated under continuous flow mode for 3 months, producing an effluent suitable for drinking water in terms of nitrates and nitrites (<50 mg NO<\/span>3<\/span>–<\/span>\u00a0L<\/span>-1<\/span>; 0 mg NO<\/span>2<\/span>–<\/span>\u00a0L<\/span>-1<\/span>). A maximum nitrate removal rate of 0.9 \u00b1 0.1 kg NO<\/span>3<\/span>–<\/span>\u00a0m<\/span>-3<\/span>\u00a0d<\/span>-1<\/span>\u00a0(efficiency 82 \u00b1 18 %) was achieved at a cathodic hydraulic retention time (HRT<\/span>cat<\/span>) of 2.0 h with a competitive energy consumption of 4.3 \u00b1 0.4 kWh kg<\/span>-1<\/span>\u00a0NO<\/span>3<\/span>–<\/span>. Under these conditions, the techno-economic analysis estimated an operational cost of 0.40 \u20ac m<\/span>-3<\/span>. Simultaneously, microbiological analyses revealed structural heterogeneity in the reactor, with denitrification functionality concentrated predominantly from the centre to the upper section of the reactor. The most abundant groups were Pseudomonadaceae, Rhizobiaceae, Gallionellaceae, and Xanthomonadaceae. In conclusion, this pilot plant represents a significant advancement in implementing this technology on a larger scale, validating its effectiveness in terms of nitrate removal and cost-effectiveness. Moreover, the results validate the electro-bioremediation in a real environment and encourage further investigation of its potential as a water treatment.\u00a0<\/span><\/p>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t
