Abstract
EN UN METODO PARA FILTRAR UNA SUSPENSION A TRAVES DE UN FILTRO ESTACIONARIO (1A, 1B) QUE TIENE UN ELEMENTO FILTRADOR VERTICAL DISPUESTO EN UN VASO DE PRESION (A, B) Y PARA REALIZAR EL REACONDICIONAMIENTO DEL FILTRO DESPUES DE LA OPERACION DE FILTRADO, EL LIQUIDO FILTRADO SE DESCARGA DEL FONDO DEL ELEMENTO FILTRADOR (27) DURANTE LA MAYOR PARTE DE LA OPERACION DE FILTRADO. DESPUES DEL FILTRADO, LA SUSPENSION NO FILTRADA SE DESCARGA DE UNA FORMA CONOCIDA DESDE EL VASO DE PRESION (A, B) PARA HACERLO VOLVER MAS TARDE HASTA LA ENTRADA (2A, 2B) PARA LA SUSPENSION. A CONTINUACION, SE REALIZA UN LAVADO CON OTRO MEDIO DIFERENTE AL LIQUIDO FILTRADO, ESTANDO ABIERTA UNA SALIDA (12A, 12B) PARA EL MATERIAL DEPOSITADO SOBRE EL ELEMENTO FILTRADOR PARA SEPARAR DICHO MATERIAL JUNTO CON EL MEDIO CON QUE SE EFECTUO EL LAVADO. PREFERIBLEMENTE, ANTES DEL LAVADO TIENE LUGAR EL SECADO DEL MATERIAL DEPOSITADO SOBRE EL ELEMENTO FILTRADOR (27) POR MEDIO DE UN GAS QUE CIRCULA EN EL INTERIOR DE LA PLANTA FILTRADORA.
