Lewatit® S 1568 is a food grade, gel-type, strongly acidic cation exchange resin based on a styrene-divinylbenzene copolymer. The favorable kinetics allow a distinctly higher operating capacity as this applies to comparable ion exchange resins with a heterodisperse bead size distribution. A much better total capacity enables long cycle times with a low leakage and economic quantities of regenerants. Lewatit S 1568 is very suitable for:- the softening of aqueous solutions, specially of juices occurring in the production of sugar and pectin
- the decationization of solutions of organic products, e.g. beets, sugar cane, starch sugar, glycerol, gelatin, food grade acids etc.
- the production of amino acids e.g. lysine
Lewatit S 1568 provides the resin filling with the following features:- a high exchange capacities in the regeneration and loading processes
- a very good utilization of the total capacity
- a low demand for wash water
- a continuous flow of regeneration agents, water and solutions, equally shaped working zone
- an almost linear pressure loss gradient along the whole bed depth, therefore and operation at higher bed depths is possible
- an outstanding separation of components in the mixed bed filter.
If using Lewatit S 1568 for treating potable water and the a.m. aqueous solutions, you have to follow our recommendations for the start-up which are available on request.Information provided by Lanxess. |
