| Resumen: | Este estudio se llevó a cabo para analizar la incidencia de los medios filtrantes en la eliminación biológica de nitrógeno y fósforo presentes en aguas colectadas en una fuente natural. Se utilizó un biofiltro de cuatro etapas, anaerobia-aerobia-anóxica y aerobia. Fue posible evaluar dos tipos diferentes de medios filtrantes, estropajo y PVC, seleccionados por su bajo costo y por ser poco convencionales. Se analizó la concentración de nitratos y fosfatos en el agua de entrada y de salida del biofiltro y la cantidad de unidades formadoras de colonias de bacterias fosfatosolubilizadoras adheridas a los medios filtrantes de la etapa anaerobia. Se determinó que el estropajo ofrece mayor estabilidad para el sosten de biopelículas bacterianas y por lo tanto para el buen desempeño de los biofiltros.

| Abstract: | This study was developed in order to analyse the incidence of filter media in the Process of nitrogen and phosphorus removal present in water collected from a natural Source. A four stage biofilter anaerobic, aerobic, anoxic and aerobic was used. It was Posible evaluate two different kinds of filter media, scourer and PVC. The selection of the filter media was based on the low cost and low conventionality. It was analyzed the nitrate and phosphate concentration from the inlet and outlet wáter and the Quantity of colony formation units adhered to the filter media in the anaerobic stage. It was determined that the scourer offered most biofilm stability for the support of the Bacterial biofilm and therefore for a better biofilter performance. |
