  • METHOD FOR PRODUCING POTASSIUM SULFATE AND SODIUM CHLORIDE FROM WASTEWATER
    Publication number: 20200290886
    Abstract: A method of producing potassium sulfate by employing sodium sulfate and potassium chloride sources is disclosed. The method includes a crystallization process that yields a mother liquor containing sulfate, sodium and chloride. The mother liquor is directed to an anion segregation unit that produces a reject or retentate rich in sulfate which is recycled and employed in the production of the potassium sulfate. Further, the anion segregation unit produces a permeate that is depleted in sulfate but includes sodium and chloride and is directed to a sodium chloride crystallizer for producing sodium chloride.
    Type: Application

  • Method for manufacturing and/or packaging a chip
    Patent number: 10099218
    Abstract: In one aspect, disclosed herein are methods for packaging biochips, including microfluidic chips. The method can comprise bonding a substrate and a cover slide, packaging the bonded chip, creating a vacuum in the package, and applying a pressure on the packaged chip. The method is particularly useful for minimizing bubble formation during low-cost and mass production of microfluidic chips.
