Lewatit S 1568

Print
Lewatit® S 1568 is a new developed food grade, strongly acid, gelular cation exchange resin with beads of uniform size (monodisperse) based on a styrene-divinylbenzene copolymer. The monodisperse beads are chemically and osmotically highly stable. The optimized kinetics lead to an increased operating capacity compared to ion exchange resins with heterodisperse bead size distribuion. An strong improved value of the total capacity provides additionally for long running times with low leakage and economical regeneration amount.

Lewatit® S 1568 is especially applicable for:
» softening of solutions, especially for thin juices of the sugar and pectin industries
» decationonisation of solutions of organic products, e.g. sugar beet, sugar cane, starch sugar, glycerine, gelatine, whey and food acids etc.
» extraction of amino acids, e.g. lysine

 
Lewatit® S 1568 adds special features to the resin bed:
» high exchange flow rates during regeneration and loading
» good utilization of the total capacity
» low sweeten-on-, sweeten-off- and rinse water demand
» homogeneous throughput of regenerants, water and solutions; therefore an homogeneous working zone
» nearly linear pressure drop gradient for the whole bed depth; therefore an operation with higher bed depth possible
» good separation behavior of the components in a mixed bed application

  

When using Lewatit® S 1568 to treat potable water and the aqueous solutions listed above, special care should be given to the initial cycles of the new resin. Please refer to the recommended start-up conditions available on request.
