We proposed a modified layout of sequential anaerobic–aerobic sludge digestion.
- bel">•
Post-aerobic digestion was performed under mesophilic conditions.
- bel">•
Increased aerobic temperature increased volatile solids removal (up to 32%).
- bel">•
Increased aerobic temperature increased nitrogen removal (up to 99%).
- bel">•
Increased temperature did not consistently affect sludge hygienization.
