Abstract

EL OBJETO DE LA INVENCION ES UN METODO Y APARATO PARA SECAR LODOS EN EL QUE EL LODO (6) ES PRIMERO VERTIDO EN UN FILTRO DE MASA (1) SOBRE UN MATERIAL DE FILTRO (2). AQUI SE LE PERMITE PRECIPITARSE COMO UN LODO RIGIDO, QUE ES RECOLECTADO PARA SECARLO POSTERIORMENTE. ANTES DE QUE EL LODO (6) SEA VERTIDO, UN TEJIDO (7), CON UNA PENETRABILIDAD AL AGUA EN LA ESCALA DE DE VOORST MAYOR A 80 L/M{SUP,2}, MAS PREFERIBLEMENTE MAS DE 200 L/M{SUP,2} S, ES ESPARCIDO SOBRE EL MATERIAL DE FILTRO (2). EL LODO PRECIPITADO SE LEVANTA DEL FILTRO (1) MEDIANTE UNA BOLSA (12) FORMADA DE ESTE TEJIDO (7), EL PRECIPITADO FORMADO SOBRE LA SUPERFICIE INTERNA DEL CUAL ACTUA MAS TARDE DONDE LA BOLSA HA SIDO SEPARADA DEL MATERIAL DE FILTRO (2).
