  • Patent number: 9333443
    Abstract: Versions of the invention include methods for reducing microbubbles in liquids treated by heat or mass exchange devices. The exchange devices may be conditioned by having gases in crevices and surfaces displaced by a liquid. The methods can be used to prepare liquids with reduced numbers of microbubbles.
    Type: Grant

    Date of Patent: May 10, 2016
    Assignee: Entegris, Inc.
    Inventors: Joseph Zahka, Aiwen Wu
  • Patent number: 9297374
    Abstract: Systems and methods relating to filtration in a pump are described. Even more particularly, systems and methods relate to optimizing operating routines of a pump based on the filter used with the pump. A system controlling a pump can receive filter information and process fluid information and select a priming routine for the filter based on the filter information and process fluid information. The pump can be operated according to the selected priming routine that includes a back pressure step to pressurize the filter from downstream.

  • Publication number: 20120128505
    Abstract: The disclosure describes systems and methods relating generally to filtration. Even more particularly, embodiments described herein relate to optimizing operating routines of a pump based on filter. Embodiments of priming routines described herein can perform a back pressure step to pressurize the filter from downstream and a back flush step to flush the filter from downstream.
