Abstract

Key findings

  • Ion exchange membranes can effectively reconcentrate diluted human urine with high efficiency and low energy consumption.
  • The use of bioelectrochemical systems with ion exchange membranes can reduce the energy required for urine reconcentration by up to 70%.
  • The reconcentrated urine can be reused as a nutrient-rich fertilizer, reducing wastewater treatment costs and environmental pollution.
