Lewatit® S 1668 is a food grade, gel-type, strongly acidic cation exchange resin based on a styrene-divinylbenzene copolymer. The optimized kinetics lead to an increased operating capacity compared to ion exchange resins with heterodisperse bead size distribution. A strong improved value of the total capacity provides additionally for lng running times with low leakage and economical regeneration amount. Lewatit S 1668 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 1668 provides the resin filling with the following features:- a high exchange capacities in the regeneration and loading processes
- a good utilization of the total capacity
- a low sweeten-on-, sweeten off- and rinse water demand
- an almost linear pressure loss gradient along the whole bed depth, therefore and operation at higher bed depths is possible
- good separation of components in the mixed bed filter.
If using Lewatit S 1668 to treat potable water dn the aqueous solutions listed above, special care should be given to the initial cycles of the new resin.Information provided by Lanxess. |
