IntegraPac™ IP-51 Industrial Grade UF Module DupPont Equivalent

Product Introduction

The IntegraPac™ IP-51 Industrial Grade Ultrafiltration (UF) Module is a compact, high-efficiency filtration unit designed to meet the demanding needs of modern water and wastewater treatment systems. This module is manufactured as a full-performance equivalent to the original Dupont/DOW IntegraPac™ IP-51, offering identical hydraulic performance, membrane specifications, and physical configuration—making it a seamless alternative or replacement in both new and retrofit UF system installations.

Engineered with outside-in hollow fiber PVDF (polyvinylidene fluoride) membranes, the IP-51 delivers superior filtration precision (down to 0.03 microns), mechanical robustness, and outstanding resistance to chemicals and fouling. Its modular design supports easy integration into skid-mounted or frame-based systems, and the compact size allows for higher membrane density per footprint, reducing space and installation costs.

From municipal drinking water treatment and seawater desalination pretreatment to food & beverage, pharmaceuticals, and power plants—the IP-51 is a reliable, long-life solution trusted across industries.

Working Principle

The IntegraPac™ IP-51 module uses a hollow fiber membrane filtration process. It adopts an outside-in flow pattern, where feed water flows around the outside of the hollow fibers, and filtered water (permeate) passes through the membrane walls into the center of the fibers.

Filtration Steps:

1.    Feed water enters the module and flows over the outer membrane surface of the fibers.

2.    Particles, colloids, bacteria, and viruses larger than 0.03 microns are blocked by the membrane surface.

3.    Permeate water flows through the fibers to the permeate port.

4.    Periodic backwashing and chemical cleaning (CIP) remove accumulated impurities and restore permeability.

This continuous separation process ensures consistent filtration performance, high water recovery, and low energy consumption.
