Remoción de cromo de aguas residuales de curtiembres utilizando ceniza volante

Abstract

RESUMEN: Se presenta un medito simple y económico para la remoción de cromo de aguas residuales de la industria de curtimbres utilizando ceniza volante. La operación de remoción de cromo se lleva a cabo en forma discontinua utilizando como variables la masa de ceniza volante, el tiempo de contacto y la temperatura o el PH, las cuales se optimizan mediante un diseño de experimentos, de Box-Wilson. Los resultados fueron exitosos y pudo pasarse de una concentraciones finales de 0.008 ppm para Cr+3 y Cr+6, respectivamente, cumpliendo con las exigencias gubernamentales sobre este tipo de desechos.
