Abstract

Key findings

  • The MDC-MEC system achieved a power density of 2.5 W/m² and a water flux of 0.35 L/m²/h, indicating efficient wastewater treatment and electricity generation.
  • The system's energy-positive operation was attributed to the simultaneous production of electricity and freshwater, with a net energy output of 1.2 kWh/m³.
  • The MDC-MEC system showed promise for treating wastewater with high salinity and nutrient levels, and could be scaled up for practical applications.
