Abstract

LA PRESENTE INVENCION SE REFIERE A UN METODO DE FILTRADO, EN EL QUE LA SUSPENSION A FILTRAR PASA EN CONTACTO CON LA SUPERFICIE DE FILTRADO DEL ELEMENTO DE FILTRO, Y EN DONDE DEBIDO A LA DIFERENCIA DE PRESION QUE PREVALECE A LO LARGO DE LA SUPERFICIE DE FILTRADO, EL FILTRADO FLUYE A TRAVES DE DICHA SUPERFICIE Y LOS SOLIDOS SEPARADOS PERMANECEN SUSTANCIALMENTE EN LA SUSPENSION. DE ACUERDO CON LA INVENCION, LA SUSPENSION A FILTRAR PASA PARA FLUIR HACIA ABAJO A LO LARGO DE LA SUPERFICIE DE FILTRADO, DONDE EL FILTRADO QUE PASA POR LA SUPERFICIE DE FILTRACION SE REALIZA DESDE LA PELICULA DESCENDENTE Y LOS SOLIDOS SEPARADOS SE DESCARGAN CON LA PELICULA DESCENDENTE SIN FORMAR UNA CAPA DE SOLIDOS DAÑINOS SOBRE LA SUPERFICIE DE FILTRADO. SE GENERA UNA PELICULA DESCENDENTE DE LIQUIDO SOBRE LA SUPERFICIE DE FILTRADO RECIRCULANDO LA SUSPENSION DESDE LA PARTE INFERIOR DEL FILTRO A LA SUPERIOR DEL ELEMENTO DE FILTRO. LA INVENCION TAMBIEN SE REFIERE A UN APARATO PARA REALIZAR EL METODO, QUE PUEDE APLICARSEESPECIALMENTE PARA CLARIFICAR UNA SOLUCION CRUDA.
