Highly cross-linked polystyrene-divinylbenzene matrix with uniform spherical beads for consistent hydraulic performance.
Sulfonic acid functional groups provide strong acidity and excellent cation exchange capacity across wide pH ranges (0–14).
Superior chemical stability in oxidizing environments and resistance to osmotic shock during repeated regeneration cycles.
Optimized particle size distribution (0.3–1.2 mm) ensures low pressure drop and high flow efficiency in fixed-bed systems.
Low soluble organic content and minimal fines generation, meeting stringent requirements for ultrapure water production.
Primary demineralization in power plant boiler feedwater treatment systems.
Softening of industrial process water in food & beverage and pharmaceutical manufacturing.
Cation removal prior to mixed-bed polishing in semiconductor-grade ultrapure water (UPW) plants.
Metal recovery and wastewater pretreatment in electroplating and metal finishing industries.
Pre-treatment for reverse osmosis (RO) systems to prevent scaling by removing hardness ions.
