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.
