Experience and lessons learned from sewage sludge pyrolysis in Australia

摘要

Management of sewage sludge via "publicly acceptable" methods is becoming increasingly difficult, primarily due,to health and environmental concerns with respect to reuse of the product in agriculture. Consequently thermal processes are gaining popularity with significantly increased interest being shown in pyrolysis,and gasification processes, due to their "non-incineration status". One such process is the ENERSLUDGE(TM) technology which has been developed and commercialised by Environmental Solutions International Ltd (ESI). The world's first commercial ENERSLUDGE(TM) plant is located at the Subiaco Wastewater Treatment Plant (WWTP) that was handed over to the client, the Water Corporation of Western Australia in June 2001. Extensive design knowledge and operational experience has now been accumulated from this commercial pyrolysis facility and future applications of the technology will benefit immensely from the lessons learned and experience gained from this facility.
