Abstract [en]

The deammonification process is a new biological promising method for a separate treatment ofammonium-rich digester supernatant. Its application can significantly reduce the nitrogen load inWastewater Treatment Plants (WWTPs). The method is a two-step process and it can beaccomplished in two separate stages (partial nitritation and Anammox) or in a singe one (CANON).Both these systems were tested at pilot plants: the CANON process in a laboratory-scale plant whilepartial nitritation/Anammox in a technical-scale one. The pilot plants were filled with Kaldnes ringsas biofilm carriers and supplied with supernatant, coming from digested sludge dewatering at theBromma and Himmerfjärden WWTPs, Stockholm, Sweden. The supernatant main ions - ammoniumand hydrogen carbonate - were converted during the processes to carbon dioxide and nitrogen gasmolecules and therefore the process performance could be followed by conductivity measurements.The experiments proved that conductivity was an easy and simple method to monitor the nitrogenremoval processes. Moreover, the data from on-line conductivity instruments, installed in theAnammox reactor of the technical-scale pilot plant, showed great similarity with the manualmeasurements.
