  • Advantages of Uniform Particle Sized Ion Exchange Resins
    . Although new resin product development has been limited by this manufacturing process, ion exchange process application technology continued to develop with the introduction of e.g. mixed beds, layered beds and packed bed systems. In an attempt to overcome the disadvantages of a polydispersed bead

    . with a polydispersed particle-sized distribution. Although new resin product development has been limited by this. manufacturing process, ion exchange process application technology continued to develop with the introduction of e.g. mixed beds, layered beds and packed bed systems. In an attempt

    of the condensate polishers (CP) with respect to effluent water. quality and service cycle run length: • In-vessel mixing of the freshly regenerated mixed resin. • Extending the regeneration of the cation exchange resin. The in-vessel mixing uses compressed air to re-mix the condensate polisher resin

    concentrations. In the summer of 2002, Millstone conducted bench scale testing of a strongly acidic cation resin fully. converted to the ETA form. This test utilized a mixed bed of the ETA form cation and a hydroxide form. anion to determine impurity removal efficiency during a simulated seawater in-leakage

    in this particular example did feed both process. areas and consisted of a separate bed ion exchange system followed by mixed. bed polishers. All pressure vessels were made of epoxy lined carbon steel,. ASME code constructed and stamped for 100 psig. Separately each vessel had a. Res-Kem Corp. 800-323-1983 Phone
  • 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
  • Improving Outlet Water Quality of RO and EDI Systems (.pdf)
    RO membranes coupled with EDI/CDI technology are rapidly gaining acceptance in the production of high purity water. Coupling the two technologies offers many advantages to the conventional RO mixed bed system design. The overall performance of a RO-EDI/CDI system can be improved by removing

    specification. the right. Carbon Dioxide and Conductivity. When ion exchange is used to polish reverse osmosis. membrane (RO) permeate, CO2 needs to be controlled. This is true for conventional mixed bed ion exchange and EDI. technologies. Excessive CO2 is the leading cause of an EDI. system not meeting
