Highly stable macroporous strong acid cation exchange resin based on sulfonated polystyrene-divinylbenzene matrix.
Exceptional resistance to osmotic shock and mechanical degradation, ensuring long service life in demanding cyclic operations.
Optimized particle size distribution (0.45–1.25 mm) for low pressure drop and uniform flow dynamics in fixed-bed systems.
Low soluble organic carbon (SOC) release, meeting stringent requirements for ultrapure water production.
Regenerable with standard sodium chloride or sulfuric acid solutions, supporting cost-effective and sustainable operation.
Polishing step in power plant high-purity boiler feedwater treatment.
Final cation removal in semiconductor-grade ultrapure water (UPW) systems.
Softening and decationization in pharmaceutical process water systems compliant with USP/EP standards.
Pre-treatment for reverse osmosis (RO) and electrodeionization (EDI) units in critical industrial applications.
Removal of heavy metal cations (e.g., Cu²⁺, Ni²⁺, Zn²⁺) from metal finishing rinse waters.
