Macroporous structure ensures excellent physical stability and resistance to osmotic shock during repeated regeneration cycles.
Highly cross-linked polystyrene-divinylbenzene matrix provides superior mechanical strength and long service life in high-flow industrial systems.
Sulfonic acid functional groups deliver strong cation exchange capacity with consistent performance across wide pH ranges (0–14).
Low fines content (<0.2%) minimizes pressure drop and prevents column channeling in packed-bed applications.
Optimized particle size distribution (0.3–1.2 mm) ensures uniform hydraulic flow and maximizes mass transfer efficiency.
Softening of boiler feed water and process water in power generation and petrochemical plants.
Pretreatment for reverse osmosis (RO) and electrodeionization (EDI) systems to protect membranes from scaling ions.
Metal recovery and purification in hydrometallurgical processes, including copper, nickel, and cobalt leach solutions.
Catalytic support in esterification and hydrolysis reactions due to its robust acidic functionality and thermal stability.
Removal of heavy metal cations (e.g., Pb²⁺, Cd²⁺, Cr³⁺) from industrial wastewater prior to discharge or reuse.
