HYDRAcap80 Industrial Grade UF Module Hydranautics​ Equivalent

Product Introduction

The HYDRAcap80 Industrial Grade Ultrafiltration (UF) Module is a high-capacity, high-efficiency membrane filtration product designed to serve as a direct replacement for the Hydranautics HYDRAcap®80. Developed for demanding industrial and municipal applications, this module provides superior filtration of suspended solids, bacteria, viruses, and colloids from a wide variety of water sources.

Manufactured using polyethersulfone (PES) hollow fiber membranes, the HYDRAcap80 module delivers consistent performance, low fouling rates, and strong chemical resistance. The outside-in filtration design ensures durability and a high membrane surface area, making it suitable for large-scale water treatment systems.

With seamless compatibility with the original HYDRAcap®80, this module is ideal for system retrofits or expansions. Its low-pressure operation, long service life, and ease of maintenance make it a dependable choice for users looking to reduce operational costs without compromising water quality.

Working Principle

The HYDRAcap80 UF module operates using the outside-in filtration principle—a highly effective process that physically separates contaminants from water using hollow fiber membranes.

Filtration Steps:

1.    Feed water enters the module and flows around the outside of the hollow fibers.

2.    Contaminants such as suspended solids, microorganisms, viruses, and colloids are trapped on the outer surface of the membrane.

3.    Clean water flows through the membrane wall and is collected inside the fibers as permeate.

4.    Permeate exits the module via the central outlet.

5.    Periodically, a backwash or air scour is initiated to clean the membrane surface.

6.    For more intensive cleaning, chemical cleaning-in-place (CIP) is conducted to remove accumulated fouling and restore performance.

This design ensures continuous filtration with minimal downtime, making it highly reliable for uninterrupted system operation.
