Abstract

SE PRESENTA UN PROCESO EN DONDE DICHOS EFLUENTES CONTIENEN COMO SUS IMPUREZAS PRINCIPALES CLORO HIDRINAS, GLICOL, ALCOHOL IPSOPROPIL Y CLORURO DE SODIO. DICHO PROCESO COMPRENDE LOS SIGUIENTES PASOS: A) EL TRATAMIENTO HIDROLITICO DEL EFLUENTE BAJO CONDICIONES ALCALINAS, HASTA QUE EL CONTENIDO DEL EFLUENTE DE EPICLOROHIDRINA SE REDUCE HASTA VALORES DE ALREDEDOR DE 75% PPM, Y EL CONTENIDO DE GLICOL DEL EFLUENTE SE REDUCE HASTA VALORES MENORES DE ALREDEDOR DE 4.000 PPM; B) LA SEPARACION DE ALREDEDOR DEL 90% DEL CLORURO DE SODIO DEL EFLUENTE HIDRLIZADO; Y C) LA DIGESTION ANAEROBICA DEL EFLUENTE HIDRLIZADO PRIVADO DEL CLORURO DE SODIO DESPUES DE LA DISOLUCION PRELIMINAR, NEUTRALIZACION E INTEGRACION CON NITROGENO Y FUENTES FOSFOREAS. EL PASO B PUEDE LLEVARSE A CABO POR MEDIO DE UN PROCESO DE CONCENTRACION DEL EFLUENTE, PARA PROVOCAR QUE EL CLORURO DE SODIO SE PRECIPITA O MEDIANTE EL SOMETIMIENTO DEL MISMO EFLUENTE A UN TRATAMIENTO DE ELECTRODIALISIS.
