Abstract

PROCEDIMIENTO DE TRATAMIENTO DE AGUAS QUE CONTIENEN SULFUROS. CONSTA DE LAS SIGUIENTES ETAPAS: 1<002> OXIDACION CATALITICA DE LOS SULFUROS PRESENTES EN AGUA A AZUFRE ELEMENTAL. 2<002> FLOCULACION DEL AGUA RESULTANTE CON UN AGENTE DE FLOCULACION, PREFERENTEMENTE UN COMPUESTO DE ALUMINIO, EN PRESENCIA DE UN POLIELECTROLITRO ANIONICO. COMO CATALIZADOR, PUEDE EMPLEARSE UN SULFATO, HALURO O SIMILAR DE UN METAL DEL GRUPO VII O VIII TAL COMO NIQUEL, COBALTO, PALADIO O MANGANESO. SON SUFICIENTES CANTIDADES DE CATALIZADOR DEL ORDEN DE 10 A 30 PPM. EL OXIDANTE EMPLEADO ES PREFERENTEMENTE OXIGENO DEL AIRE. EL PH ESTA COMPUESTO ENTRE 8 Y 9.
