Features Of Lanxes-s LEWATIT K 2431 Ion Exchange Resin

  1. Highly selective for potassium ions (K⁺) in mixed-cation aqueous systems.

  2. Stable polyacrylic matrix ensures excellent mechanical strength and pressure drop performance in fixed-bed operations.

  3. Low sodium leakage and high regeneration efficiency with potassium chloride (KCl) brine.

  4. Optimized bead uniformity and narrow particle size distribution for consistent hydraulic performance.

  5. Chemically resistant to oxidants and compatible with standard industrial regeneration protocols.

Typical Applications Of Lanxes-s LEWATIT K 2431 Ion Exchange Resin

  1. Potassium enrichment and sodium removal in food-grade syrup and sweetener processing.

  2. Targeted K⁺ recovery from process effluents in pharmaceutical manufacturing.

  3. Pre-concentration of potassium prior to crystallization in fertilizer production streams.

  4. Ion adjustment in high-purity water circuits requiring low Na⁺ carryover.

  5. Selective softening where calcium/magnesium removal must preserve potassium content.
