Start-up analysis of partial nitrification process in SBR reactors for different initial conditions

There are a lot of technical solutions that are designed to improve the efficiency of nitrogen removal from wastewater. One of the most interesting processes are autotrophic nitrogen removal process ANAMMOX. Essential for the ANAMMOX process is prepare the wastewater containing the correct proportion of ammonium and nitrite. The study tested strategies for start-up of the partial nitrification from wastewater streams from sludge dewatering after the methane fermentation process. The start-up was tested for partial nitrification process from full nitrification process in pilot scale. For the initial conditions was developed strategies. In this strategy was chosen initial parameters such as pH, temperature, and DO to the partial nitrification process will be well.
