Se han realizado experimentos con trazadores en una batería industrial de una planta de
tratamiento de agua. El comportamiento del flujo es complejo porque incluye la superposición de un flujo estocástico, que es intrínseco al proceso mismo, y de un flujo no estocástico inducido por fuertes corrientes locales en la superficie. Estas corrientes no son estocásticas porque son diferentes de una instalación a otra, aunque todas sean idénticas. Se ha propuesto un modelo general para simular todo el comportamiento del proceso. El modelo se compone de dos partes: la primera, describe el comportamiento del flujo estocástico, y es el mismo para cada unidad; el segundo está adaptado para representar los atajos turbulentos en la superficie de algunas unidades. Se ha determinado que los parámetros de la parte estocástica son consistentes con la descripción física del proceso. El valor del número de Peclet del atajo es una función monótona del caudal. A pesar de las incertidumbres restantes debido tanto a la complejidad del flujo como a los problemas específicos de las mediciones de trazadores en grandes plantas de tratamiento de aguas industriales, este artículo propone una extensión de las aplicaciones de los experimentos e interpretación de trazadores.
