In this research a pilot plant was operated with automated inflow control based on oxygen uptake rate (OUR). A strategy was developed in order to achieve partial nitrification (NOB wash out) at 25 ºC, 1.1 mg O2 L-1 and pH of 8.3 using the appropriate OUR set point for the automatic controller. Steady partial nitrification was run for 120 days with an averaged nitrogen loading rate of 0.5 g N g-1 VSS d-1. Molecular microbiology tools such as FISH (fluorescence in situ hybridization) and flow cytometry were used in order to quantify the nitrification population an demonstrate the NOB wash out.
Throughout this work mathematical modelling using Matlab® was used to predict the pilot plant performance and design the controller after a comprehensive model parameters calibration with specific experiments.
