Estudio comparativo de retención de cromo hexavalente en aguas sintéticas utilizando como lecho filtrante tres fibras naturales como alternativa de biorremediación

The industrial effluents of chrome-plating, tanning of skins, protection of woods and textiles contribute to the surface waters relatively high amounts of chromium. This type of waste with the presence of chromium, are transformed into contaminants for surface water bodies and groundwater, in which this pollutant has a long residence time. Therefore, this research aims to perform a comparative study of hexavalent chromium retention (Cr +6) in synthetic waters using as filter bed the fibers Musa textilis (Abaca), Furcraea andina (Cabuya) and Musa paradisiaca (banana rachis) as an alternative of bioremediation. From this study it was found that the most effective removal percentage occurred in Musa Paradisiaca fiber (banana rachis) with a value of 69.80% cut fiber at 1cm with a low flow rate, Musa Textilis (Abaca) fibers retain the Cr + 6 in 30.17% at medium and low high concentrations with normal fiber and the Furcraea Andina fiber (Cabuya) retains Cr + 6 in 37.53% at low concentration with normal fiber. Concluding that Musa Paradisiaca is the most effective, low cost and environmentally friendly fiber when reusing waste.
