  • Method for purifying and recovering solvent from ion exchange processes
    Patent number: 11478749
    Abstract: The invention relates to a system and method of use for concentrating a solution that is eluted from an ion exchange process (elution solution) during an ion exchange regeneration using the osmotic pressure of the salt saturator. This method recovers solvent from the elution solution that could be used in a future ion exchange regeneration process. The concentration of the elution solution may include the precipitation and removal of solids from the elution solution.
    Type: Grant

  • Method and Device for Testing Effectiveness of Magnetic Treatment of Feed Water for Reducing Mineral Scaling in Reverse Osmosis Processes
    Publication number: 20180180581
    Abstract: A benchtop device flow setup for determining the effectiveness of magnetic treatment of feed water for reducing mineral scaling includes two similar branches, both equipped with a reverse osmosis membrane and a pump that operate in the transient regime at the same flow rate and transmembrane pressure. The flow setup is further fed with a solution at the same level of supersaturation measured in a stirred reactor, however, only one branch exposes the feed to a magnetic field.
