Lewatit® S 5528 is a food grade, macroporous, strongly basic anion exchange resin (type I) 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 5528 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 5528 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 be regeneration with a neutral or alkaline sodium chloride solution. Lewatit S 5528 is therefore highly recommended for use wherever complete and rapid removal of a relatively high concentration of organic substances is required. A use in combination with other Lewatit adsorber resins such as Lewatit S 6368 allows simultaneous fine polishing. When using Lewatit S 5528 to treat potable water and the aqueous solutions listed above, special care should be given to the initial cycles of the new resin.Information provided by Lanxess. |
