Lanxess LEWATIT® CNP 80 WS Acrylic-based Cation Exchange Resin
Categories: Polymer; Thermoset

Material Notes: Lewatit® CNP 80 WS is a weakly acidic, macroporous, acrylic-based cation exchange resin of standard bead size distribution used in modern counter-current regenerated systems. Due to its very high total and operating capacity, excellent chemical and mechanical stability together with high resistance to osmotic shock, it is preferable used for dealkalization. The arrangement with strong dissociated cation exchanger (Lewatit MonoPlus S 108), in demineralization units (e.g Lewatit VWS System) leads to higher regeneration efficiency. As Lewatit CNP 80 WS only requires a low excess of regenerant acid, it can be can be economically used in the following applications:
  • Dealkalization of industrial water operated with co-current or modern counter-current systems like e.g. Lewatit WS System, Lewatit Liftbed System, Lewatit Multistep System or Lewatit Rinsebed Systems
  • In combination with a strong acidic cation exchange resin, e.g. Lewatit MonoPlus S 108, in a decationization unit for the demineralization of water
  • Removal of temporary hardness (hardness associated with alkalinity)
  • In a single bed unit downstream from the demineralization unit (polisher) for the removal of cations present as hydroxides at flow rates up to 50 m/h
  • In produced water soften as single filter unit or in combination with Lewatit S 1567, as polisher
  • In its sodium-form for the removal/extraction of heavy metals such as copper, nickel and zinc from electroplating rinse waters at pH-value Lewatit CNP 80 WS can be used in conjunction with all conventional ion exchange processes. For other systems there are special grades of this resin with a suitable bead size distribution.
