TIEMPOS ÓPTIMOS DE REMOCIÓN DE Fe+2 y Mn+2 POR AIREACIÓN TIPO CASCADA, CON TRES TIPOS DE MEDIOS DE CONTACTO

Abstract

In this article it sample an experimental procedure on small scale is developed that allows to establish the optimal times in which it removes the iron and manganese by gas transference from the ventilation and by ion transfer through the adsorption when making contact with three different conventional filtering media (volcanic Stone, clay, pumice). In it realized tests with contact means was obtained very satisfactory results, it establish Fe⁺² and Mn⁺² reductions by oxidation by ventilation, at efficiency levels majors to 70%, to equal optimal times of operation by ventilation to 90, 720, and 666, minutes for each means of contact respectively, and 420 minutes for the aerated water without means of contact. The clay removed 74,68% of iron and 100% of manganese in 720 minutes of ventilation, It considered that this evaluation had the best results of ventilation time.
