LEWATIT® CNP 80 WS

Lewatit® CNP 80 WS is a weakly acidic, macroporous, acrylic-based cation exchange resin of special 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 100), in demineralization units (e.g.Lewatit®VWS System) leads to higher regeneration efficiency.

Properties and benefits
As Lewatit® CNP 80 WS only requires a low excess of regenerant acid, it 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 System
  • in combination with a strong acidic cation exchange resin, e.g. Lewatit® MonoPlus S 100, in a decationization unit for the demineralisation of water
  • removal of temporary hardness (hardness associated with alkalinity)
  • in a single bed unit downstream from a demineralization unit (polisher) for the removal of cations present as hydroxides at flow rates up to 50 m/h
  • in produced water softening as single filter unit or in combination with Lewatit® S 1467 as polisher
  • in its sodium-form for the removal/extraction of heavy metals such as copper, nickel and zinc fromelectroplating rinse waters at a pH-value > 5 in absence of calcium and complexing agents.
