DESCRIPTION |
Dow Chemical 650C H Monosphere Acid Cation Exchange Resin is a premium-grade, uniform particle size strong acid cation exchange resin specifically engineered for high-performance applications requiring exceptional physical stability and chemical efficiency. The "Monosphere" technology ensures beads of consistent size and shape, providing optimal hydraulic characteristics.
Condensate Polishing in Power Plants: Primary application for removing corrosion products and ionic impurities from power plant condensate.
Ultra-Pure Water Production: Essential for mixed-bed units in semiconductor, pharmaceutical, and power industries requiring the highest water purity.
Chemical Processing: Used as a catalyst in esterification, hydrolysis, and other chemical reactions requiring strong acid catalysis.
Industrial Water Demineralization: Employed in primary cation units for high-efficiency removal of cations from raw water.
Food and Pharmaceutical Processing: Suitable for applications requiring FDA-compliant ion exchange resins for purification processes.

Suspended Solids: Pre-filtration recommended for turbidity >1 NTU
Backwash Requirements: Regular backwashing at 8-12 m/h to maintain bed classification
Quality Certification: Complies with FDA 21 CFR 173.25 for food contact applications
ADVANTAGES |
Uniform Particle Size Distribution: Monosphere beads provide lower pressure drop, better flow distribution, and improved regeneration efficiency.
High Mechanical Strength: Exceptional physical durability reduces bead fracture and fines generation during operation and backwashing.
Excellent Kinetic Characteristics: Rapid exchange kinetics enable higher flow rates and more compact system design.
Consistent Performance: Predictable and reproducible results due to uniform bead size and quality control.
Thermal Stability: Maintains structural integrity and exchange capacity at elevated temperatures up to 150°C.
