The removal of organic matter (cod), nitrogen and phosphorus from wastewater is required to avoid the phenomenon of eutrophication. Eutrophication is defined as the over-enrichment of a water body with nutrients, resulting in excessive growth of organisms and depletion of oxygen concentration. A model for each of the main biological nutrient removal processes is developed, calibrated and validated in this thesis: biological cod removal, niological nitrogen oxidation (nitrification), enhanced biological phosphorus removal (ebpr)  these models were developed so that they could be calibrated with common wwtp measurements: oxygen and ph. Therefore, the models are calibrated using respirometric and titrimetric techniques. On the one hand, respirometry is the measurement and interpretation of biological oxygen consumption rate. The oxygen uptake rate (our) profile gives information of the process rate. On the other hand, titrimetric techniques are based on the measurement of the proton production rate (hpr) through the amount of acid and base dosed to the system to maintain the ph constant.  moreover, mathematical tools should be used to ensure the reliability of the parameter estimation values. Confidence intervals are as important as the parameter estimation value itself. The parameter estimation error assessment methodology used in this thesis is based on the fisher information matrix (fim), which is regarded as an indicator of the amount of information contained in the experimental data.  a new model for the description of the biological cod removal process was developed. The major achievement of this model was the inclusion of the simultaneous growth and storage on external substrate process. Moreover, it was extended to be calibrated with titrimetric measurements. This means that the model described the evo<\/p>\n<p>&nbsp;<\/p>\n<h3>Datos acad\u00e9micos de la tesis doctoral \u00ab<strong>\u00abmodelling biological organic matter and nutrient removal processes
