[Denitrifying phosphorus removal in a Modified University of Cape Town (MUCT) process treating domestic wastewater under nitrification and nitritation].

The performance of denitrifying phosphorus removal under nitrification and nitritation was investigated in a lab-scale Modified University of Cape Town (MUCT) process treating real domestic wastewater with low C/N ratio. The experimental results of 180 days showed that nitritation was achieved at short hydraulic retention time (HRT) and low dissolved oxygen (DO) of 0.3-0.
