Groundwater contamination by nitrate and salinity poses serious health concerns, compromising access to safe drinking water. This study overcomes a major limitation of prior electro-bioremediation studies by achieving simultaneous nitrate and salinity removal to satisfy drinking water compliance while co-producing chlorine as an on-site disinfectant. Systematic evaluation of multiple key operating parameters such as current density (j), anode\/cathode area ratio (A\/C), and anodic hydraulic configuration, on the performance of a three-chamber bioelectrochemical system (BES) identified the conditions that maximize both contaminant removal and chlorine recovery. Under optimal conditions (j<\/em>\u202f=\u202f2.4\u202fA\u202fm\u207b\u00b2, A\/C = 0.6:1, and batch-operated anode), the system achieved complete nitrate removal and reduced electrical conductivity below drinking water standards, with a low specific energy consumption (SECv<\/sub>\u00a0= 1.42\u202f\u00b1\u202f0.02 kWh m\u22123<\/sup>treated water<\/sub>). Successful validation of the results with real contaminated groundwater confirmed the system\u2019s applicability and robustness, addressing a key gap in previous proof-of-concept studies. Further process intensification based on reduction of the hydraulic retention time (from 7 to 5\u202fh) led to a 44\u202f% increase in nitrate removal rate (from 100.2\u202f\u00b1\u202f1.9 to 144.6\u202f\u00b1\u202f0.5 mgNO3<\/sub>–<\/sup>-N L\u22121<\/sup>\u00a0d\u22121<\/sup>), alongside reduction in SECV<\/sub>\u00a0(from 1.53\u202f\u00b1\u202f0.05 to 1.17\u202f\u00b1\u202f0.04 kWh m\u22123<\/sup>treated water<\/sub>), with only a decrease in chlorine recovery (from 30.7\u202f\u00b1\u202f2.3 to 20.1\u202f\u00b1\u202f2.3\u202fg\u202fm\u22123<\/sup>treated water<\/sub>). Microbial community analysis revealed the dominance of\u00a0Achromobacter<\/em>\u00a0in the biocathodic biofilm with both synthetic and real groundwater, highlighting its contribution to cathodic denitrification under different influents. These findings represent a significant advancement toward sustainable groundwater remediation, supporting practical feasibility for cost-effective scale-up and integration with resource recovery.<\/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
