Abstract

Key findings

  • Electrodes can provide electrons for sulfate reduction, bypassing the need for external electron donors.
  • Bioelectrochemical systems can achieve high sulfate reduction rates, making them a promising technology for wastewater treatment.
  • The use of electrodes as electron donors can reduce the cost and complexity of sulfate reduction processes.
