- •
A Sequential Batch Reactor (SBR) was used to perform complete partial nitrification.
- •
A novel DO control strategy depending on using the mixing speed has been developed.
- •
The effect of DO, pH, alkalinity, FA and FNA acid have been evaluated.
- •
The SBR has been successfully running at nitrogen loading rate up to 1.2 kg/(m3.d).
- •
The SBR has achieved an ARE of 99% and a NAR of 93% at NLR of 1.2 kg/(m3.d).
