  • Method for the extrusion of ceramic filter media
    Patent number: 5925309
    Abstract: A method of manufacturing ceramic filter media for water filters involves the steps of mixing a plurality of raw ceramic materials and a plurality of extrusion-aid materials to form a mixture of constituent materials, extruding the constituent materials to form tubular filter media, drying the tubular filter media, and firing the tubular filter media to create ceramic tubular filter media. The step of drying the tubular filter media preferably comprises placing the tubular filter media on top of rotating rollers which dries the tubular filter media evenly and preserves the desired characteristics of the tubular filter media.
    Type: Grant
    Filed: August 6, 1997
    Date of Patent: July 20, 1999
    Assignee: Mountain Safety Research
    Inventors: Osgood J. Whittemore, Chris J. Adams, Daniel J. Vorhis
