Abstract
PROCEDIMIENTO PARA LA ELIMINACION DE COLORANTES, PIGMENTOS Y/O BLANQUEADORES OPTICOS DE LAS AGUAS RESIDUALES.CONSISTE EN AGREGAR FLOCULANTES PRIMARIOS EN FORMA DE COMPUESTOS DE HIERRO Y ALUMINIO Y FLOCULANTES AUXILIARES SECUNDARIOS EN FORMA DE DERIVADOS DE CIANAMIDA, MELAMINA O PIRIDINA O DE OTROS COMPUESTOS ORGANICOS CATIONACTIVOS, SEPARANDOSE DEL AGUA EL COAGULADO RESULTANTE. LA EXTRACCION SE LLEVA A CABO POR UN SISTEMA EN EL QUE LOS FLOCULANTES PRIMARIOS Y LOS FLOCULANTES SECUNDARIOS SE AGREGAN AL AGUA BRUTA DELANTE DE UN LECHO FILTRANTE DE ELEMENTOS GRANULADOS QUE SIRVE PARA EL FILTRADO, DE FORMA TAL QUE LA FLOCULACION O LA FORMACION DE FLOCULOS SE LLEVA A CABO EN LA MASA FILTRANTE HABIENDOSE PREVISTO, ENTRE EL ULTIMO PUNTO DE DOSIFICACION DEL FLOCULANTE PRINCIPAL O AUXILIAR Y LA MASA FILTRANTE, UN TIEMPO MEDIO DE TRATAMIENTO DEL AGUA RESIDUAL A DECOLORAR INFERIOR A 45 MINUTOS.
