Abstract: A filter device has a securing device (10) for securely fixing a filter element (12) on an element mount (14). The securing device (10) includes a securing ring (16), which may be moved by a control device (18) from a position in which the filter element (12) on the element mount (14) is released into a position in which the filter element (12) is fixed on the element mount (14).

Abstract: A filter device together with a filter element for such a device. A filter device having a securing device (10) for securely fixing a filter element (12) on an element mount (14) is characterized in that the securing device (10) includes a securing means (16), which may be moved by means of a control device (18) from a position in which the filter element (12) on the element mount (14) is released into a position in which the filter element (12) is fixed on the element mount (14).

Abstract: An improved method and apparatus for processing deleterious material on a floating vessel during transportation from a well to a disposal site. The vessel contains equipment for the slurrification and agitation of the deleterious material. Such equipment includes storage tanks, slurrification units, and agitation units, as well as transfer equipment such as flow lines and vacuum or pump means. The deleterious material is transferred from the drill site to the storage tanks on the vessel. The vessel then transports the material to a disposal site, such as an injection well. During transportation, the deleterious material is processed. Such processing can include slurrification and/or agitation of the deleterious material to maintain the slurry, adding fluid if necessary. Once at the disposal site, the deleterious material slurry is then transferred from the vessel to the disposal site.
