- •
Swine waste was treated in anaerobic digesters with varying SRT.
- •
Digester centrate was used as an organic carbon source for denitrification.
- •
Excellent volatile solids removal, CH4 yield and CH4 production rates were observed.
- •
Digester centrate supported denitrification, with highest rates at a 21 day SRT.
