DuPont™ IntegraTec™ XP 77 IP IG Ultrafiltration Module for Industrial Water, Wastewater Reuse and RO Pretreatment | High-Recovery, Fouling-Resistant PVDF Membrane

Product Description

Reliable, High-Recovery Ultrafiltration for Industrial and Municipal Water Treatment

The DuPont™ IntegraTec™ XP 77 IP IG is a pressurized ultrafiltration module designed for industrial utility water treatment, industrial wastewater reuse, municipal wastewater filtration, and reverse osmosis pretreatment. Combining proven PVDF hollow-fiber technology with an installation-ready rack design, it delivers reliable contaminant removal, high operating recovery, and scalable performance for demanding water treatment systems.

The module features DuPont’s proven XP™ hydrophilic PVDF hollow fibers with a nominal pore size of 0.03 μm. This advanced membrane technology provides high removal of colloidal particles, bacteria, and viruses while offering excellent permeability, wettability, fouling resistance, and chlorine tolerance. The result is stable filtration performance, effective membrane cleaning, and dependable operation across a wide range of industrial and municipal feedwater conditions.

With 77 m² (829 ft²) of active membrane area, the XP 77 IP IG supports a maximum filtration flow of 8.5 m³/h (37.4 gpm) under the specified operating limits. Its outside-in, dead-end filtration configuration helps maximize productivity while maintaining a practical system footprint.

Engineered for Scalable, Efficient Operation

An innovative end-cap design enables direct module coupling in DuPont™ IntegraTec™ IP skids, simplifying rack assembly and allowing treatment capacity to be expanded as demand grows. High air-scouring tolerance supports efficient backwashing and high operating recovery, while the recommended maintenance-cleaning protocol helps reduce chemical consumption.

Constructed with robust wetted materials, the XP 77 IP IG is engineered for long service life, straightforward installation, and low routine maintenance. It is an effective ultrafiltration solution for facilities seeking to improve water reuse, protect downstream RO membranes, or increase treatment reliability without adding unnecessary system complexity.
