LEWATIT® S 1568

Lewatit® S 1568 > is a food grade, gel-type, strongly acidic cation exchange resin based on a styrene-divinylbenzene copolymer. The favourable kinetics allows 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 pectine
• 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 an 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.
