Vladimir Georgievich Pugachev has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Non-woven polymeric fabric including agglomerates of aluminum hydroxide nano-fibers for filtering water
    Patent number: 8033400
    Abstract: The invention concerns the production of filter materials for the purification and disinfection of water, water solutions and other liquids, as well as for sterilizing filtration of injections and other solutions, for concentration of biomolecules in physiological liquids, concentration and extraction of viruses, preparation of apyrogenic water, in biocatalytic diaphragm reactors. The invention solves the problems of a new filter material production, characterized by high sorption properties, high retention efficiency of submicron electronegative particles, microorganisms, submicron non-polar particles and chemical contaminations, and, at the same time, characterized by low hydrodynamic resistance. A base of filter material is the nonwoven organic synthetic polymeric fabric, modified by the aluminum hydroxide particles, fixed to the surface of base fibers for improvement of its sorption properties and for making it positively charged.
