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 facilitate the kinetics of adsorption and desorption. Substances a adsorbed, e.g. high-molecular hydrophilic anionic organic substances and colorants from sugar solution, 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 concentrations of organic substances is required. Use in combination with other Lewatit adsorber resins such as Lewatit S 6368 allows simultaneous fien 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.Information provided by Lanxess. |
