OBSERVATIONERAVSLAMEGENSKAPER 1 EN SBR-REAKTOR MED NITRIFIERING AV REJEKTVATTEN / Observations of the Sludge Properties in a SBR Reactorwith Nitrification of Reject Water
At Bromma wastewater treatment plant experiments have been performed with nitrification of reject water by use of SBR technology (Sequencing Batch Reactor technology). Obtained results have shown that the sludge has good sedimentation properties and a high proportion of nitrifying bacteria. It was possible to decantate in pilot plant studies at least 40 % of the working volume and to maintain a high nitrification rate more than 40 g NH4-N/kg VSS/ h). In the SBR reactor the efficiency exceeded 1 m3 reject water/m3 d corresponding to about 1 kg NH-N/m3/d. Ammonium oxidation was likely due to Nitrosolobus. “Complete abstract not presented.”
