LEWATIT® CNP P

Lewatit® CNP P is a macroporous, weakly acidic cation exchange resin based on a crosslinked polyacrylate. Its beads have got a special size distribution for the use in household filter systems and technical drinking water plants.
In the hydrogen form Lewatit® CNP P is suitable for:

  • the decarbonisation and softening of drinking water, e.g. brewery water treatment
  • the use in household filter systems


Since it has got a low requirement for regenerants, the Lewatit® CNP P is a particulary economical product for the decarbonisation of drinking water and liquids which are used as foodstuffs or in the production of foodstuffs.


If using Lewatit® CNP P to treat potable water and the aqueous solutions listed above, special care should be given to the initial cycles of the new resin. Please refer to the recommended start-up conditions available on request.
