Output 1. A system to convert POME waste to energy via biogas is established by introducing carbon materials that enhance direct interspecies electron transfer.
1.1 Low-cost carbon material is developed
1.2 Hydraulic retention time is shortened
1.3 COD of POME is reduced
1.4 More methane is generated from POME wastewater.
1.5 Higher purity of upgraded biogas is obtained
1.6 Higher electricity is generated by SOFC.
1.7 An electrochemical methanation system is developed.
