Lewatit® S 1668is 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 distribuion. An strong improved value of the total capacity provides additionally for long running times with low leakage and economical regeneration amount.
Lewatit® S 1668 is especially applicable for:
Lewatit® S 1668 adds special features to the resin bed:
If using Lewatit® S 1668 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.
