|a Existing titrimetric techniques rely on a well defined hydrogen ion production rate. In particular, they are only suitable in circumstances in which constant background pH influencing reactions take place. This is rarely the case due to the presence of the carbonate acid/base system. In this paper, a model, which describes the influence of the nitrification process on pH and accounts for the action of the carbonate system, is presented. The validity of the model is tested by comparison of model predictions for the important state variables with that of experimental data from a batch oxidation of ammonium nitrogen. The two cases studied are the responses of an endogenously respiring nitrifying sludge to: an ammonium chloride pulse and a pulse of both bicarbonate and ammonium chloride. The results are most encouraging as the dynamic HPR response is mirrored by the model simulation. Furthermore, using the model for data interpretation, the initial nitrogen substrate levels are recovered. It is shown that this could not have been achieved in either case using existing titrimetric techniques
