NITRIFICATION PARAMETER MEASUREMENT FOR PLANT DESIGN : EXPERIENCE AND EXPERIMENTAL ISSUES WITH NEW METHODS

This paper describes three bench-scale methods for measuring the nitrifier maximum specific growth rate, ìAUT: the Low F/M SBR, Washout and High F/M methods. During the WERF project, the importance of pH and temperature control was investigated briefly; this paper summarizes further experimental work performed to address these issues. A summary of ìAUT measurements in a number of locations and using the different measurement techniques is provided.
