Properties and benefits
On account of its high total capacity, excellent mechanical and chemical stability and osmotic properties, in the buffered hydrogen form, by avoiding any mineral acidic effluent,  Lewatit® S 8229 is suitable for:

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

Since it has a low regenerant requirement, Lewatit®S 8229    is a particulary economical product for the decarbonisation of drinking water and liquids which are used as foodstuffs or in the production of foodstuffs.

Lewatit® S 8229 complies with current German legislation on food and food-contact uses and is tested and certified under NSF/ANSI Standard 61 "Drinking Water System components - Health Effects".
Lewatit®S 8229 is in compliance with the European Resolution ResAP (2004)3 (superseding the former Resolution AP (97)1) with regard to Total Organic Carbon (TOC) release according the AFNOR test T90-601.
