Resumen
En este trabajo se efectuó un estudio de modelos de infiltración en aguas subterráneas, lo cual permitió realizar la propuesta de un modelo preliminar de transporte de contaminantes en medios porosos con potenciales aplicaciones para la comunidad de bacterias anammox en acuíferos que se encuentran expuestos a la contaminación a causa de la actividad agrícola debido al uso de fertilizantes ricos en nitratos. Se propuso un modelo físico–matemático preliminar al cual se le dio solución analítica y se presentaron los métodos experimentales para calcular los parámetros que se utilizaron en la ecuación. Se evaluó el modelo para tres tipos de concentraciones como un caso de prueba y se aplicó para dos casos reales. Los resultados afirman que para las cargas utilizadas existió inhibición del anammox a partir de los 10 días.

The model was evaluated for three types of concentrations as a test case and was applied for two real cases. Results confirm that for the loads used there was anammox inhibition after 10 days.
