Anammox process is happening to be in the center of interest for several years. Implementing partial nitrification/Anammox process into main stream of wastewater would result in a great improvement of sustainable technologies for reducing nitrogen in environment. However, Great chalange fo Anammox bacteria in main stream is the low temperature which is a strong inhibiting factor for them. In this study pilot-scale MBBR reactor was operated to investigate the influence of low temperatures in Anammox process. Two different phases operated at 13 and 16°C were investigated during five months. SAA, OUR and online measurements were used to observe process capacity in low temperatures. Deammonification process was found to be stable in 13°C. Moreover, Anammox bacteria capacity to convert nitrogen to nitrogen gas was found in even 5°C. Satisfactory results for Deammonification process in low temperatures may result in future application of Anammox process in full-scale plant for main stream of wastewater.
