Title: Innovations of Thomas F. Stocker
Introduction
Thomas F. Stocker is an accomplished inventor based in Saint Paul, MN (US). He holds a total of 3 patents that showcase his contributions to the field of membrane technology. His work primarily focuses on improving the performance and durability of reverse osmosis membranes.
Latest Patents
One of his latest patents is titled "Use of inorganic ammonium cation salts to maintain the flux and salt." This invention aims to prevent the deterioration of the flux and salt rejection characteristics of polyamide, thin-film, composite reverse osmosis membranes when subjected to high-temperature drying conditions. The process involves incorporating an unsubstituted inorganic ammonium cation salt of an acid into the manufacturing process, which can be added before or after the membrane is formed by interfacial polymerization.
Another significant patent is "Novel polyamide reverse osmosis membranes." This patent describes an improved composite polyamide membrane and methods for its production. The membrane is prepared using a cationic polymeric wetting agent in an aqueous solution containing a polyfunctional amine reactant, which is interfacially polymerized with an acyl halide. The resulting membrane exhibits a remarkable combination of high water flux, high rejection of divalent anion salts, variable sodium chloride rejection, and good caustic resistance at low operating pressures.
