Benefits of thermophlic digestion at Christchurch wastewater treatment plant
19/10/2011
In 2010, two 7,000m³ anaerobic digesters were commissioned at the Christchurch Wastewater Treatment Plant (CWTP), which now operates a Temperature Phased Anaerobic Digestion (TPAD) process – thermophilic and mesophilic in series. This paper outlines the thermophilic commissioning process including difficulties, solutions and contingency plans, and the improvement in digester performance.
