Lewatit® S 6268 is a food grade, gelular, monodisperse, strongly basic (type I) anion exchange resin based on a styrene-divinylbenzene copolymer. On account of its special gel matrix with an integrated high porosity and special features such as outstanding capacity, demineralization of waters with high organic load or decolorization of sugar (can or beet) solutions are the preferred applications. Further, the higher thermal stability in comparison to acrylic resins and the outstanding physical and osmotic stability give Lewatit S 6268 an additional advantage. The optimized kinetic increase the operating capacity, in comparison with ion exchange resins of heterodisperse bead size distribution. Lewatit S 6268 (in its Hydroxide form) is especially suitable for the removal of acid and simultaneous decolorization of solutions of organic substances e.g. sugar, gelatin, glycerin, grape must, whey, fruit concentrates etc. Lewatit S 6268 (in its chloride form) is especially suitable for:- the decolorization of sugar syrup (beet or cane), glycerin, grape must, fruit juices
- organic traps (scavengers) used for the treatment of waters containing high concentrations of organics.
Lewatit S 6268 adds special features to the resin bed:- high flow rate during regeneration and loading
- a good utilization of the total capacity
- a low demand for rinse water
- a homogeneous throughput of regenerants, water and solutions, resulting in a homogeneous operating zone
- a virtually linear pressure drop gradients across the entire bed depth, allowing operation with higher bed depths
- a good separation of the components in mixed bed applications
When using Lewatit S 6268 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. |
