The DuPont UF XP 77 IG is a high-performance ion exchange membrane designed for chlor-alkali electrolysis applications. It delivers high current efficiency (≥96%) and low energy consumption, enabling cost-effective production of caustic soda (NaOH), chlorine (Cl₂), and hydrogen (H₂).
- Ultra-Strong PVDF Membrane Material - Resists tearing, abrasion, and chemical degradation
- Superior Chemical Tolerance - Withstands aggressive cleaning agents and extreme pH conditions
- Outer-to-In Filtration Design - Handles high solids content and turbid feed water with minimal fouling
- Precision-Level Filtration Efficiency - Removes microorganisms, colloids, and fine particulates effectively
- Optimized for Heavy-Duty Systems - Ideal for large-scale industrial installations requiring extended service life
- Industrial Wastewater Reclamation (chemical processing, mining, power generation)
- Seawater Pretreatment for Desalination Plants
- Aggressive Process Water Treatment (textile dyeing, metal finishing, petrochemical)
- Municipal Water Purification in High-Stress Environments
- Material Science: Hydrophilic PVDF with enhanced structural integrity
- Filtration Mechanism: Outer-pressure configuration for high solids tolerance
- Operational Resilience: Broad chemical and thermal operating window
- Certifications: Meets international standards for industrial water safety
The XP 77 IG stands apart through its uncompromising resilience in corrosive and high-load environments. Its advanced polymer formulation resists common membrane failure modes, while the optimized fiber geometry balances flux stability with energy efficiency.
