Lewatit® S 7468 is a food grade, macroporous, monodisperse, strongly basic (type II0 anion exchange resin based on a styrene-divinylbenzene copolymer, designed for demineralization and decolorization applications. Due to its special macroporous structure, the Lewatit S 7468 stands for the effective adsorption an desorption of organic substances. Lewatit S 7468 is especially suitable for:- the demineralization of water for food applications operated with co-current or modern counter-current systems like e.g. Lewatit WS System, Lewatit Liftbed System or Lewatit Rinsebed System
- polishing systems or convention mixed bed arrangement in combination with Lewatit S 2568 H
- working mixed beds in combination with Lewatit S 2568 H
Lewatit S 7468 adds special features to the resin bed:- high flow rates 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 gradient 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 7468 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. |
