MOFⅣB/UOFⅣ UF Module Motimo Equivalent

Product Introduction

The MOFⅣB / UOFⅣ Ultrafiltration (UF) Module is an industrial-grade hollow fiber membrane solution, precisely engineered to serve as a high-quality equivalent to the Motimo UF series. This module is designed for rigorous applications in municipal water treatment, industrial process water purification, and wastewater reclamation. Built using high-strength PVDF hollow fibers, the MOFⅣB / UOFⅣ offers outstanding chemical resistance, long operational life, and consistent filtration performance under varied conditions.

With its reliable separation efficiency and modular adaptability, the MOFⅣB / UOFⅣ serves as a versatile alternative for customers seeking cost-effective yet high-performance ultrafiltration technology.

Working Principle

The MOFⅣB / UOFⅣ UF Module operates on the outside-in hollow fiber membrane principle. In this filtration process, feed water flows around the external surface of the hollow fibers. As water permeates the membrane walls, suspended solids and harmful microorganisms are retained on the outer surface while clean water passes through to the inside of the fibers.

Step-by-Step Process:

1.    Feedwater Introduction
Untreated water enters the module and flows outside the hollow fiber bundles.

2.    Physical Filtration
With a nominal pore size of approximately 0.03 microns, the PVDF membrane blocks particles, bacteria, colloids, and some viruses.

3.    Permeate Collection
Filtered water collects inside the lumen of the fibers and is routed to the outlet port.

4.    Cleaning Cycle
Periodic backflushing, air scouring, and chemical cleaning (CIP) restore permeability and extend the module's service life.

This mechanical barrier approach offers a chemical-free primary filtration method, making it suitable for sensitive or eco-friendly applications.
