Abstract

An anaerobic waste stabilisation pond (AWSP) has been assessed to enable energy neutral wastewater treatment at decentralised works. During start-up, chemical oxygen demand (COD) removal efficiency was comparable to full-scale AWSPs operated in moderate climates, thereby establishing the potential for treating wastewater in the less conducive European climate. The linear relationship between COD removal and time demonstrated that the AWSP had not reached steady-state, indicating further improvement in COD removal is expected. Data modelled on a 10 000 population equivalent catchment indicated that integrating an AWSP upstream of trickling filters presented the optimum configuration to minimise on-site electrical demand. Anaerobic WSP can generate sufficient electricity onsite to offset electrical demand. Anaerobic WSP can generate sufficient electricity onsite to offset electrical demand, recording a net on-site energy balance of +379.5 kWhe d(-1). Using an AWSP for on-site sludge treatment also reduced exported sludge volume, markedly reducing the wastewater treatment total carbon dioxide equivalent emissions (carbon footprint) compared to conventional technologies. This study established AWSP as a significant future technology for sustainable decentralised wastewater treatment.
