Retrofit For DuPont IntegraTec™ XP 77 IP Ultrafiltration Module
- 100% Plug-and-Play Retrofit: Standard 77 m² active area with exact industrial dimensions for seamless, direct replacement—no piping or skid modifications required
- Extreme Fiber Strength: Extraordinary 1,526 cN tensile strength (62%+ higher than standard membranes) to completely eliminate fiber breakage and leakage during heavy backwashing
- Heavy-Duty Pressure Rating: Certified 6.5 Bar (94.2 psig) max inlet pressure to safely absorb severe 75–80 psig system pressure spikes and water hammers
- High Real-World Flux: Proven tap water production of 13.0 m³/h at 1 Bar, delivering massive flow efficiency and lower operational energy consumption
- Superior TMP Tolerance: Maximum Transmembrane Pressure (TMP) extended to 2.0 Bar, providing higher fouling resistance and significantly longer cycles between chemical cleanings (CIP)
Introduction: AALUF IP-77XP Ultrafiltration Membrane Module
The AALUF IP-77XP Ultrafiltration Membrane Module is a heavy-duty, high-performance PVDF hollow fiber UF module specifically engineered for direct, seamless retrofit of the DuPont IntegraTec™ XP 77 IP (formerly Dow IntegraFlux™) ultrafiltration modules.
With an identical pressurized configuration, standard 77 m² (829 ft²) of active filtration area, and exact physical dimensions, the AALUF IP-77XP allows for a 100% "plug-and-play" replacement without requiring any piping modifications or structural changes to your existing skids.
Designed to overcome the common industry pain points of fiber breakage and strict plant safety overpressure protocols, the AALUF IP-77XP combines massive flow efficiency with an upgraded, market-leading mechanical safety margin.
Key Features & Technical Advantages
Heavy-Duty Pressure Rating (6.5 Bar / 94.2 psig): While standard modules or older generations are rated for lower pressures, the AALUF IP-77XP boasts a certified Maximum Inlet Pressure of 6.5 Bar. This significantly exceeds DuPont's standard 4.75 Bar rating, providing a generous safety cushion that easily absorbs sudden water hammers and feed pressure spikes up to 75–80 psig without triggering safety overpressure alarms or facility shutdowns.
1526 cN Tensile Strength: Utilizing an advanced PVDF hollow fiber formulation, our membrane fibers deliver an extraordinary 1526 cN tensile strength—over 60% higher than conventional alternatives. This robust "skeleton" guarantees that the fibers remain intact under severe hydraulic shocks, backwashing, and high-TMP air-scouring conditions.
High Flux Efficiency & Precision : With a refined, highly porous yet compact pore structure (<0.02 µm), the module delivers a robust design flux baseline of >150 L/(m²·h·bar). In real-world tap water testing, a single module reliably achieves a stable production flow rate of 13.0 m³/h at just 1 bar, ensuring maximum water yield with lower energy consumption.
Higher Operating TMP (2.0 Bar): An increased maximum Transmembrane Pressure (TMP) tolerance of 2.0 Bar allows for flexible operations, extended filtration cycles, and reliable performance even during challenging raw water turbidities before requiring chemical cleanings (CIP).

Target Applications & Industries
The AALUF IP-77XP is widely utilized in large-scale, high-demand water treatment systems where system uptime and strict mechanical reliability are paramount:
Seawater Desalination Pre-treatment (SWRO): Protects downstream reverse osmosis membranes from colloidal fouling, organics, and micro-particles in harsh marine environments.
Industrial Wastewater Reuse & Zero Liquid Discharge (ZLD): Highly resilient against chemical cleaning agents and high-pressure filtration demands in textile, chemical, and automotive plants.
Municipal Drinking Water Purification: Excellent rejection of bacteria, viruses, and suspended solids to meet stringent municipal turbidity standards.
Boiler Feed Water Pre-treatment: Provides ultra-clean feed water for power plants and heavy industrial boilers to prevent scaling and fouling.
