    摘要： A fiber filter, method of preparing the fiber filter, and method of treating a fluid stream with the fiber filter are disclosed. The fiber filter comprises an inert fiber matrix, water, and a substrate bound to the fiber matrix that is capable of oxidizing or neutralizing a contaminant. More specifically, the substrate bound to the fiber matrix is sodium bicarbonate, impregnated activated alumina, impregnated zeolite, or a mixture thereof. The impregnate is a permanganate salt, sodium bicarbonate, or a mixture thereof. Improved efficiency of removal of undesirable compounds such as hydrogen sulfide and sulfur dioxide from fluid streams is achieved.

    摘要： A process for removing particulate contaminants from a fluid is disclosed, the fluid being passed through a filter media comprising cellulose fiber and silica based particulate or fiber filter elements and a charge modifying amount of a cationic charge modifying system bonded to the surfaces thereof. One component of the charge modifying system is a primary charge modifying agent characterized as a water soluble organic polymer capable of being adsorbed into the filter elements and having a molecular weight greater than about 1000. Each monomer of the polymer can have at least one epoxide group capable of bonding to the surface of the filter elements and at least one quaternary ammonium group. A portion of the epoxy groups on the organic polymer are bonded to the secondary charge modifying agent.

    摘要： A flat annular disc filter paper has a plurality of randomly oriented fibers at its surface. The paper is impregnated with a phenolic resin so as to resist compression of the disc and swelling of the paper. The filter paper is made by soaking the paper in the resin, heating the paper and resin so as to burn and melt the resin into close contact with the paper and rolling the filter paper at a temperature above ambient temperature.
