Abstract

Key findings

  • The modified MEC showed a 2.5-fold increase in hydrogen production compared to a traditional MEC.
  • The system was able to remove 90% of the chemical oxygen demand (COD) from the distillery wastewater.
  • The biohydrogen production rate was 1.2 L/kg COD removed, which is a significant improvement over previous studies.
