Abstract
METODO E INSTALACION PARA RECUPERAR SEGUN UN PROCESO CONTINUO EL CROMO TRIVALENTE DE AGUAS RESIDUALES DE TENERIA. CONSISTENTE EN TRATAR LAS AGUAS RESIDUALES DE TENERIA, QUE CONTIENEN POR LO MEOS 0,7 POR 100 DE CR+++, CON BASE PARA OBTENER UN PH ENTRE 7 Y 8, CALENTANDOSE DICHAS AGUAS A UNA TEMPERATURA COMPRENDIDA ENTRE 30 GRADOS CENTIGRADOS Y LA DE EBULLICION, Y SOMETIENDOSE A FILTRACION CONUN FILTRO GIRATORIO, QUE FUNCIONA DE MODO CONTINUO. EL FILTRO ESTA PROVISTO DE UN TEJIDO FILTRANTE CON UNA PERMEABILIDAD AL AIRE EN LA GAMA DE 23 A 35 LITROS/DM2/MINUTO, A UNA PRESION DE 2 ATMOSFERAS. DE ESTE MODO, LA FASE ACUOSA EXTRAIDA DEL FILTRO ESTA SUSTANCIALMENTE EXENTA DE CROMO, CON LO QUE OBTIENE UNA TORTA SOLIDA, A LA QUE SE ADICIONA ACIDO SULFURICO PARA CONSEGUIR UN PH INFERIOR A 2,5, CON LO QUE, EN DEFINITIVA, SE OBTIENE LA DISOLUCION DE CROMO EN FORMA DE SULFATO CROMICO.
