Zachary Helm 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).

  • Water treatment systems and methods
    Patent number: 10384967
    Abstract: Separation processes using osmotically driven membrane systems are disclosed generally involving the extraction of solvent from a first solution to concentrate a solute by using a second concentrated solution to draw the solvent from the first solution across a semi-permeable membrane. Pre-treatment and post-treatment may also enhance the osmotically driven membrane processes.
    Type: Grant
    Filed: July 23, 2015
    Date of Patent: August 20, 2019
    Assignee: OASYS WATER LLC
    Inventors: Nathan T. Hancock, Marek S. Nowosielski-Slepowron, Zachary Helm, Christopher Drover, George Bischoff
  • Systems and methods for improving performance of osmotically driven membrane systems
    Patent number: 10384167
    Abstract: The invention relates to repairing and/or modifying a surface of a membrane in osmotically driven membrane systems by the introduction of one or more substances to the membrane.
    Type: Grant
