Evaluación de eficiencia de la harina de cáscara de plátano (Musa spp) utilizando un filtro casero, para la adsorción de hierro y manganeso en agua para consumo humano, barrio Miramayo, distrito de Yantaló – Moyobamba – San Martín

Abstract

Families living in places where there is no drinking water treatment system consume water from wells or springs, which have high concentrations of metals such as iron and manganese. Faced with this problem, the present work has focused on the search for an alternative solution through the physical treatment of well-water in the Miramayo neighborhood of Yantalo, Moyobamba, which contains adsorbed iron and manganese, by means of a filtration process, using a homemade filter composed of sand, quartz-gravel and banana peel flour (Musa spp). The key to success in this filtration process had been in determining the most efficient concentrations and temperatures of the banana peel flour, then using it in a filtration treatment. According to the results, a considerable decrease in the initial concentration of iron and manganese present in the well-water was obtained. The evaluated concentrations were 100, 150, 200, 250, 300, 350, 400 and 450g of banana peel flour (Musa spp) at different temperatures of 90, 100, 110 and 120°C. The most efficient concentrations were for iron: at a C1 (200g) and temperature of 100°C, up to 82.26% of Fe is adsorbed; for manganese: at a C1 (100g) and a temperature of 90°C, up to 89.1% Mn is adsorbed. This shows that the Fe and Mn parameters of the well-water were significantly decreased after treatment.
