| Summary: | In Singapore, municipal wastewater is currently treated in centralised wastewater treatment facilities. However, the existing paradigm for transport and centralised treatment of municipal wastewater is found unsustainable due to substantial amount of energy and water consumed. There comes the need for a more environmentally friendly treatment. Unlike the centralised concept in which the wastewater is considered as a pollutant, decentralised treatment concept utilises wastewater as resource for fertiliser, water, energy and for closing water and nutrient cycles (Elmitwalli et al., 2006). The decentralised treatment of municipal wastewater evolves from the idea of separation between grey and black water, and even between faeces and urine, represents a sustainable prospective solution for wastewater treatment. Besides the decentralised concept, anaerobic co-digestion of anthropogenic wastes has been attracting great attention in many countries, for its high potential of energy recovery and resource utilisation. |
