文摘
- •
Selection of PHA storing biomass was integrated with N removal in municipal WWTP.
- •
N removal via nitrite was achieved using fermented biowaste as carbon source.
- •
A novel aerobic feast and anoxic famine regime was adopted for PHA selection.
- •
Denitritation driven by the stored PHA was achieved with 83 ± 13% of nitrogen removal.
- •
Oxygen requirement saving of 50% was made compared to usual PHA recovery.
