Lewatit®

LEWATIT® S 5428

Lewatit® S 5428 is a food grade, macroporous, strongly basic (type I) anion exchange resin based on a
crosslinked polyacrylate. It is bead-shaped and has a special bead size distribution for use in the following
processes:

  • Co-current system
  • Counter-current systems (Lewatit® • WS system / fluidized bed)
  • Counter-current systems (Lewatit® • VWS system / compound fluidized bed)

In its chloride form, the Lewatit® S 5428 is suitable for the decolorization of:

  • syrups from sugar production, especially cane sugar
  • solutions of organic products, e. g. glycerin, amino acids

The macroporous structure and balanced resin matrix of Lewatit® S 5428 facilitate the kinetics of adsorption
and desorption. Substances adsorbed, e. g. high-molecular hydrophilic anionic organic substances and
colorants from sugar solutions, can be desorbed easily by regeneration with a neutral or alkaline sodium
chloride solution.

Lewatit® S 5428 is therefore highly recommended for use wherever complete and rapid removal of a
relatively high concentration of organic substances is required. Use in combination with other Lewatit®
adsorber resins such as Lewatit® S 6368 A allows simultaneous fine polishing.

If using Lewatit® S 5428 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.
