Properties and benefits
On account of its high total capacity, excellent mechanical and chemical stability and osmotic properties, in the hydrogen form  Lewatit® S 8227 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 8227    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 8227 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 8227 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 T 90-601.

When using Lewatit®S 8227 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 in this data sheet.
