Lewatit®

LEWATIT® S 2528

Lewatit® S 2528 is a food grade, macroporous, strongly acidic cation exchange resin based on a styrene-divinylbenzene copolymer. lt 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 systems


In its hydrogen form, Lewatit® S 2528 is suitable for:

  • the decationisation of solutions of organic products, e.g. sugar beet, sugar cane, starch sugar, and of solutions of organic products, e.g. glycerin, gelatine, whey etc...

In its sodium form, Lewatit® S 2528 is suitable for:

  • the extraction of amino acids, e.g. from molasses
  • the softening of thin juice, e.g. Gryllus process
  • the removal of alkali ions from B-green, e.g. Quentin process.


The macroporous structure of Lewatit® S 2528 facilitates the adsorption of hydrophilic highmolecular cationic organic substances. The organic substances, e.g. colorants, can easily be desorbed by regeneration with caustic soda solution.
