Lewatit® S 2528 is a food grade, macroporous, strongly acidic cation exchange resin based on a styrene-divinylbenzene copolymer. It is bead-shaped and has a special bead size distribution for a use in the following processes:- Lewatit WS system (fluidized bed)
- Lewatit VWS system (compound fluidized bed)
- Standard co current regenerated system
Lewatit S 2528 is suitable for: - the decationization of solutions of organic products, e.g. sugar beet, sugar cane, starch sugar, and of the solutions of organic products, e.g. glycerin, gelatin, whey etc..
- the softening of thin juice, e.g. Gryllus process in the sodium form
- the removal of alkali ions for B-green e.g. Quentin process.
The macroporous structure of Lewatit S 2528 facilitates the adsorption of hydrophilic high molecular cationic organic substances. The organic substances, e.g. colorants, can easily be desorbed by regeneration with caustic soda solutions. If using Lewatit S 2528 to treat potable water and aqueous solutions listed above, special care should be given to the initial cycles of the new resin.Information provided by Lanxess. |
