One of the major aspects associated with landfilling of solid wastes is related to the discharge of leachate into environment. Leachates with high ammonium nitrogen content are generally difficult to effective treat in conventional biological treatment processes. Therefore, it brings a requirement of developing new processes and technologies. Additionally, treatment procedures must consider small flow rates of leachate. The Rotating Biological Contactor (RBC) is a good example of technology for treatment such wastewaters, because of its excellent shock and toxic loading capabilities, simple process control and low energy requirements. The main objective of the presented research was to investigate a simultaneous partial nitritation/Anammox process in the rotating biological contactor. For this purpose, the lab-scale reactor was fed with real landfill leachate from two municipal landfill sites in Gliwice and Zabrze (Poland). The reactor was highly loaded up to 7 g N m-2d-1 and it was possible to obtain the maximum inorganic nitrogen removal rate of 6.2 g N m-2d-1. Achieved results proved the possibility of efficient inorganic nitrogen removal by means of partial nitritation/ Anammox process in the temperature around 20°C.
