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

Product Description

Proven Ultrafiltration Performance for Municipal and Industrial Water Treatment

The DuPont™ IntegraTec™ XP 77 IP is a pressurized hollow-fiber ultrafiltration module engineered for municipal drinking water, industrial utility water, wastewater reuse, municipal wastewater filtration, and reverse osmosis pretreatment. Combining proven membrane technology with a rack-ready module design, it delivers dependable water quality, high operating recovery, and efficient performance across demanding treatment environments.

At the core of the XP 77 IP is DuPont’s proven hydrophilic PVDF hollow-fiber membrane. Its 0.03 μm nominal pore size provides effective removal of colloidal particles and high log reduction of bacteria and viruses, helping improve treated-water quality and protect downstream processes. Excellent permeability supports productive filtration, while superior resistance to fouling and chlorine enables reliable operation and efficient membrane cleaning.

The module provides 77 m² (829 ft²) of active membrane area and supports a maximum filtration flow of 8.5 m³/h (37.4 gpm) within the specified operating limits. Its outside-in, dead-end filtration configuration is designed for high-recovery applications requiring consistent performance and a practical system footprint.

Designed for Scalable, Low-Maintenance Systems

An innovative end-cap design enables direct module coupling in DuPont™ IntegraTec™ IP rack systems, simplifying installation and supporting straightforward capacity expansion. High tolerance to air scouring promotes effective backwashing and stable operating recovery, while the recommended maintenance-cleaning protocol helps reduce chemical consumption.

Constructed with robust wetted materials, the IntegraTec™ XP 77 IP is designed for long service life and low routine maintenance. It provides plant operators and system designers with a proven ultrafiltration solution for new installations, capacity expansions, and pretreatment systems.

FAQ Content

What is the DuPont™ IntegraTec™ XP 77 IP used for?

The IntegraTec™ XP 77 IP is designed for municipal drinking water production, industrial utility water treatment, industrial wastewater reuse, municipal wastewater filtration, and pretreatment before reverse osmosis systems.

What membrane technology does the XP 77 IP use?

It uses hydrophilic PVDF hollow-fiber membrane technology with a nominal pore size of 0.03 μm. The membrane offers excellent filtration permeability, fouling resistance, chlorine tolerance, wettability, and cleanability.

What contaminants can the XP 77 IP remove?

The module is designed to provide high removal of colloidal particles and high log reduction of bacteria and viruses. Actual removal performance depends on feedwater characteristics, system design, and operating conditions.

What is the filtration capacity of the XP 77 IP?

The module contains 77 m², or 829 ft², of active membrane area. Its specified maximum filtration flow is 8.5 m³/h, or 37.4 gpm. This value is an operating limit rather than a guaranteed design flow; actual capacity should be determined according to feedwater quality and process conditions.

Why is the XP 77 IP suitable for RO pretreatment?

Its 0.03 μm ultrafiltration membrane reduces colloidal particles and microbial loading before water enters the RO system. This helps protect downstream membranes and supports more stable RO operation.

Can the XP 77 IP be used in expandable treatment systems?

Yes. The module’s end-cap design supports direct coupling in DuPont™ IntegraTec™ IP rack systems, enabling simple assembly and scalable plant expansion.
