  • Sterilization or disinfection of workpieces, including medical and dental instruments
    Patent number: 10471165
    Abstract: Devices and methods for sterilizing and/or disinfecting workpieces, such as medical and dental instruments. The device can include a chamber that receives the workpieces and can be sealed. The chamber is filled with chlorine dioxide gas to a threshold concentration and for a time sufficient to sterilize and/or disinfect the workpieces.
    Type: Grant

  • Methods for reducing scale formation on and removing deposits from heat transfer surfaces
    Patent number: 9221701
    Abstract: Disclosed are methods of operating steam generators, particularly evaporators, in hard water environments characterized by high Si and Mg content in which the pHcold of the feed water stream is maintained within a range of about 11 to 12 in order to reduce, eliminate or remove scale from internal evaporator surfaces. Additional components may be added to the feed water stream including surfactants, chelants, dispersants, sequestrants and mixtures thereof.

  • Anti-scale composition and method of use for leach fields
    Patent number: 8778049
    Abstract: Disclosed is a method for treating heap leach stacks by applying an insoluble polyimide composition, such as polysuccinimide, to the surface of an ore stack and/or incorporating the insoluble polyimide composition throughout the ore stack. The insoluble polyimide composition is then exposed to an aqueous solution to initiate hydrolysis and produce one or more water soluble products, such as hydrolyzed polyimides, polycarboxylates, polycarboxylic acids and mixtures thereof that will permeate the ore stack at a concentration sufficient to suppress scale formation within the leach stack. The water soluble products may also act to suppress scale formation in piping and channels peripheral to the leach stack, thereby reducing maintenance expenses.
