IntegraPac™ IP-77 Industrial Grade UF Module DupPont Equivalent

Product Introduction

The IntegraPac™ IP-77 Industrial Grade Ultrafiltration (UF) Module is a premium filtration component engineered for advanced water and wastewater treatment. Designed as a drop-in equivalent to the original Dupont/DOW IntegraPac™ IP-77 module, this product matches all key specifications, hydraulic performance, and physical connections—making it a seamless alternative for new installations and retrofits alike.

Manufactured with PVDF (polyvinylidene fluoride) hollow fiber membranes, the IP-77 module ensures high-efficiency removal of suspended solids, bacteria, viruses, and colloids with a filtration precision of 0.03 microns. The design emphasizes high performance, durability, and energy efficiency, making it ideal for municipal water plants, desalination systems, industrial processes, and wastewater reuse applications.

This module’s high surface area, compact design, and exceptional fouling resistance deliver reliable long-term operation even in challenging water conditions, ensuring superior water quality and lower operating costs.

Working Principle

The IntegraPac™ IP-77 UF module operates using a physical separation process via hollow fiber membrane filtration. It follows an outside-in filtration mechanism, where untreated water enters the outer shell and surrounds the membranes, while filtered water passes through the porous fiber wall into the center of the hollow fibers.

Step-by-Step Process:

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

2.    Particles larger than 0.03 microns, including bacteria and viruses, are retained on the membrane surface.

3.    Permeate water flows into the fiber lumen and exits through the permeate port.

4.    Backwashing and chemical cleaning (CIP) periodically remove fouling and restore performance.

This design ensures consistent filtration, low pressure drop, and minimal disruption during cleaning, supporting continuous operation in critical applications.
