Lewatit® S 8229 Dry is a food grade, macroporous, weakly acidic cation exchange resin based on a crosslinked polyacrylate. It is bead-shaped and has a special bead size distribution for use in household filter systems and technical drinking water plants. In its buffered hydrogen form Lewatit S 8229 Dry is suitable for the decarbonisation and softening of drinking water, e.g. brewery water treatment, and the use in household filter systems.
