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.
