DuPont™ XP 77 IG UF Membrane Grade Filtration For Challenging Water

Product Specification

DuPont™ XP 77 IG UF Membrane—Grade Filtration For Challenging Water Applications

• Product Description:

  The DuPont™ XP 77 IG is a high-performance ultrafiltration (UF) membrane engineered for extreme industrial water treatment environments. Leveraging reinforced PVDF hollow fiber technology, it delivers exceptional durability and chemical resistance in applications requiring robust filtration solutions. Designed for reliability in harsh conditions, this membrane ensures consistent water quality while minimizing operational downtime.

  Key Features:

  • 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.

  Applications:

  • 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

  Technical Highlights:

  • 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

  Competitive Advantages:

  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. This membrane is engineered to reduce lifecycle costs in applications where conventional UF membranes degrade prematurely.
