Abstract

PROCEDIMIENTO PARA FILTRAR UNA SUSPENSION LIQUIDA DE CARBON. SE AÑADE A DICHA SUSPENSION UN COPOLIMERO DE METRACRILATO DE ALCOHILO EN UNA CANTIDAD QUE INCREMENTA LA VELOCIDAD DE FILTRACION DE LA MISMA, A CONTINUACION DE LO CUAL SE FILTRA LA CITADA SUSPENSION. OPCIONALMENTE, EL COPOLIMERO A UTILIZAR PUEDE SER UN COPOLIMERO DE METRACRILATO DE ETILENO-PROPILENO. A VECES EL COPOLIMERO PUEDE ESTAR DISUELTO EN UN ACEITE LIGERO. OTRA ALTERNATIVA DE ESTE PROCEDIMIENTO CONSISTE EN DEPOSITAR UNA TORTA DE REVESTIMIENTO DE OADYUVANTE DE FILTRACION SOBRE UN ELEMENTO DEL FILTRO, HACER PASAR LA SOLUCION DEL COPOLIMERO EN ACEITE LIGERO A TRAVES DE DICHA TORTA Y SEGUIDAMENTE FILTRA LA SUSPENSION LIQUIDA DE CARBON A TRAVES DE LA TORTA Y DEL FILTRO PROPIAMENTE DICHO. CASO COADYUVANTE DE FILTRACION PUEDE EMPLEARSE TIERRA DE DIATOMEAS.
