UOT-865 UF Module Motimo Equivalent

Product Introduction

The UOT-865 Ultrafiltration (UF) Module is a premium-grade membrane solution specifically developed as a high-performance equivalent to Motimo's UOT series. It is designed for industrial and municipal water treatment applications that require consistent water quality, chemical resistance, and operational durability. Leveraging advanced PVDF hollow fiber membrane technology, the UOT-865 delivers high throughput and excellent removal efficiency for suspended solids, bacteria, colloids, and macromolecules.

Whether you're upgrading an existing Motimo UF system or deploying a new water treatment solution, the UOT-865 offers a drop-in replacement with improved performance metrics and extended service life.

Working Principle

The UOT-865 module operates on the outside-in hollow fiber filtration principle. This process involves directing the feedwater around the outer surface of the hollow fibers, where contaminants are trapped, and clean water is drawn through the pores into the lumen.

Filtration Steps:

1.    Feedwater Entry
Untreated water flows into the module and surrounds the external surface of the hollow fibers.

2.    Membrane Separation
The 0.03-micron PVDF membrane captures particulate matter, bacteria, turbidity, and other impurities.

3.    Permeate Collection
The purified water passes through the fiber walls and is collected inside the core of the fibers.

4.    Waste Discharge
Concentrated contaminants remain outside the fibers and are flushed out during backwash or air scouring.

5.    Cleaning Cycle (CIP)
To maintain optimal performance, routine physical and chemical cleanings are performed.

This physical barrier filtration method ensures a consistent and chemical-free separation process ideal for both potable and process water applications.
