FO-2218 UF Module Equivalent

Product Introduction

The SFO-2218 UF Module Equivalent is a robust, industrial-grade ultrafiltration module designed to deliver superior water treatment performance across a wide range of applications. Engineered to match the specifications and performance of the original SFO-2218, this module serves as a reliable replacement or upgrade in municipal, industrial, and commercial water treatment systems.

Utilizing advanced hollow fiber membrane technology, the SFO-2218 module provides consistent and effective separation of suspended solids, microorganisms, colloids, and macromolecules from feed water. Its efficient outside-in filtration configuration, combined with chemically resistant membrane materials, ensures long-lasting operation and minimal maintenance.

Whether used as a standalone filtration unit or as a pretreatment step for reverse osmosis (RO) systems, the SFO-2218 delivers dependable water quality and reduced operational costs.

Working Principle

The SFO-2218 UF Module operates on the principle of physical separation via hollow fiber ultrafiltration, a pressure-driven membrane process. Here’s how it works:

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

2.    Filtration occurs as water passes through the pores of the membrane (typically 0.03 microns), blocking contaminants.

3.    Permeate (clean water) flows through the hollow center of each fiber and exits through the outlet port.

4.    Rejected particles remain on the membrane's outer surface and are removed through periodic backflushing or air scouring.

This simple yet effective process achieves high removal efficiency of turbidity, pathogens, and particulates while maintaining high flux and low transmembrane pressure (TMP).
