Product Description
Compact Ultrafiltration for Space-Constrained Water Treatment Systems
The DuPont™ IntegraTec™ XP 51 IP is a compact, pressurized ultrafiltration module engineered for applications where installation height or available space is limited. Designed for municipal drinking water, industrial utility water, wastewater reuse, municipal wastewater filtration, and reverse osmosis pretreatment, it combines proven membrane performance with a shorter module configuration ideally suited to containerized and height-restricted treatment systems.
At the core of the XP 51 IP is DuPont’s proven XP™ hydrophilic PVDF hollow-fiber membrane technology. With a nominal pore size of 0.03 μm, the membrane provides high removal of colloidal particles and strong log reduction of bacteria and viruses. Excellent permeability, wettability, and cleanability help maintain dependable filtration performance, while superior resistance to fouling and chlorine supports demanding operating and cleaning conditions.
The module offers 51 m² (549 ft²) of active membrane area and a maximum filtration flow of 5.6 m³/h (24.8 gpm) under the specified operating limits. Its outside-in, dead-end filtration process supports efficient solids removal and high-recovery operation while maintaining a compact system footprint.
Designed for Easy Integration and Scalable Capacity
The XP 51 IP features an innovative end-cap design that enables direct coupling within DuPont™ IntegraTec™ IP skids. This streamlined configuration simplifies rack assembly, reduces installation complexity, and makes it easier to expand treatment capacity as demand increases.
High tolerance to air scouring supports effective backwashing and high operating recovery. Combined with an optimized maintenance-cleaning protocol, this can help reduce chemical consumption and simplify routine operation. Robust wetted materials, straightforward installation, and low maintenance requirements make the XP 51 IP a practical choice for both permanent water treatment facilities and modular containerized plants.
For operators and system integrators seeking reliable ultrafiltration performance in a shorter module format, the IntegraTec™ XP 51 IP delivers proven PVDF membrane technology, application flexibility, and scalable system integration.

FAQ Content
What is the DuPont™ IntegraTec™ XP 51 IP used for?
The IntegraTec™ XP 51 IP is designed for municipal drinking water treatment, industrial utility water, industrial wastewater reuse, municipal wastewater filtration, and reverse osmosis pretreatment. Its compact dimensions make it particularly suitable for containerized and height-restricted installations.
Why is the XP 51 IP suitable for containerized water treatment systems?
The module has a shorter overall length of approximately 1,991 mm (78.4 in) . This compact format helps system designers fit reliable ultrafiltration capacity into installations with limited vertical clearance, including modular and containerized treatment plants.
What membrane technology does the XP 51 IP use?
It uses hydrophilic PVDF hollow-fiber membrane technology with a nominal pore size of 0.03 μm. The membrane is engineered for excellent permeability, fouling resistance, chlorine tolerance, wettability, and effective cleaning.
What is the filtration capacity of the XP 51 IP?
The module provides 51 m² (549 ft²) of active membrane area and has a specified maximum filtration flow of 5.6 m³/h (24.8 gpm) . Actual design flow depends on feedwater quality, operating conditions, pretreatment, and treatment objectives.
How does the XP 51 IP support RO pretreatment?
