  • Development of Ion Exchange Resins with Ultra-Low Residuals for Condensate Polishing Applications (.pdf)
    Nuclear power plants need to minimize corrosion and corresponding deposition throughout steam/water circuits. Condensate polishers containing mixed beds of ion exchange resins play a vital role in reduction of impurities in water circulated through these polishers.
  • Ion Exchange Resin Fouling by Oil (.pdf)
    To understand the problems associated with the effects of oily waste on deionization resins, it is important to first understand the categories of oily waste materials. In general, oily wastes fall into three categories: * Free. * Emulsified. * Dissolved
  • The Advantages of Uniform Particle Sized Ion Exchange Resins (.pdf)
    styrene-divinylbenzene resins in the 40's. The production of resins in a stirred reactor results in the formation of resin beads with a polydispersed particle-sized distribution. Although new resin product development has been limited by this manufacturing process, ion exchange process application
  • DOWEX TM MONOSPHERE TM Ion Exchange Resins (.pdf)
    The Dominion Engineering Millstone Nuclear Power Station has undergone a significant performance improvement in water quality and operational efficiency of the deep-bed condensate polishers in Unit 2. The use of DOWEX TM MONOSPHERE TM 650C and 550A gel resins (now in service for more than 6 years
  • Trace Silica Measurement in the Semiconductor and Power Industries
    In the production of high purity water, dissolved silica is known to be the first ion to breakthrough when the ion-exchanger resin approaches depletion. Therefore, rinse water quality is critical to minimize defects and ensure proper performance. Much work has been done in the past decade
  • ACID SEPARATION FOR IMPURITY CONTROL AND ACID RECYCLE USING SHORT BED ION EXCHANGE
    Acid separation using short bed ion exchange is a now well established technology in copper. refinery tankhouses. Refinery bleed streams from liberator cells are treated by short bed systems. to produce an acid-free byproduct stream that contains the bleed metals and valuable nickel salts. Removing
  • Throwing it All Away
    in single-use cartridges. Downstream, disposable membrane chromatography cartridges replaced some ion exchange resins, while process engineers rethought the economics of cleaning and validating even expensive resins. In short, the high value of biotech products provides fertile ground
  • System Adjusts Juice for Greatest Palatability and Marketability at Lowest Cost (.doc)
    "Citrus" plus "ion exchange" adds up to a sweeter, more marketable juice and a happy customer . . . while duplex Newark Wire Cloth sanitary trap strainers keep the costly exchange resins in the system where they belong. Newark Wire Cloth Co. of Clifton, NJ, supplier of the essential resin traps
