摘要

Increasing interest has been given to the wastewater treatment—energy nexus due to the concern on global climate change. As such, various anaerobic processes have been investigated for energy recovery from municipal wastewater in the form of biogas.1' In this viewpoint, we argue that biogas recovery from municipal wastewater through anaerobic processes might not be economically practical and environmentally friendly due to the fact that substantial amount methane is dissolved into treated effluent.
