Highly selective for potassium (K⁺) and ammonium (NH₄⁺) ions in complex aqueous matrices.
Stable macroporous polystyrene-divinylbenzene matrix ensures robust performance under varying pH and temperature conditions.
Optimized particle size distribution (0.3–1.2 mm) enables low pressure drop and uniform flow distribution in column operation.
Excellent chemical resistance to oxidants, chlorine, and moderate concentrations of acids and alkalis.
Regenerable with standard salt solutions (e.g., NaCl), supporting sustainable cyclic operation and reduced operational costs.
Removal of ammonium from municipal and industrial wastewater prior to discharge or reuse.
Potassium recovery and concentration in food processing effluents and biogas digestate streams.
Pre-treatment for ultrapure water systems where selective monovalent cation control is required.
Softening and selective ion removal in pharmaceutical process water circuits.
Nutrient management in aquaculture and hydroponic recirculating systems.
