SFD-2860 Industrial Grade UF Module DupPont DOW Equivalent

Product Introduction

The SFD-2860 Industrial Grade UF (Ultrafiltration) Module is a high-performance water treatment solution, engineered to meet the filtration demands of modern industrial and municipal systems. Developed as a reliable equivalent to the Dupont/DOW SFD-2860 model, this module offers full compatibility in structure, dimensions, and hydraulic performance. It is the ideal replacement option for existing systems using DOW UF modules, as well as for new system designs that require long-lasting, high-quality ultrafiltration.

Constructed using hollow fiber membranes made from PVDF (polyvinylidene fluoride), the SFD-2860 ensures robust mechanical strength, excellent chemical resistance, and high filtration accuracy. It is designed for consistent operation in challenging water conditions, removing bacteria, viruses, suspended solids, and colloidal particles with ease. Whether used for drinking water purification, RO pretreatment, or wastewater recycling, the SFD-2860 module provides a dependable, low-maintenance solution.

Working Principle

Ultrafiltration is a membrane filtration process that separates particles and impurities from water using a semi-permeable membrane. The SFD-2860 module operates in an “outside-in” flow pattern, where feed water flows from the outside of the hollow fibers to the inside, while contaminants are retained on the outer surface.

Filtration Process:

1.    Feed water enters the module housing and surrounds the hollow fibers.

2.    Clean water (permeate) passes through the membrane wall into the inner core of each fiber.

3.    Contaminants, including suspended solids, microorganisms, and colloids, are blocked.

4.    Backwashing and chemical cleaning (CIP) cycles are periodically initiated to remove fouling from the membrane surface.

This process ensures stable flux, high filtration efficiency, and long membrane lifespan while operating at low pressure and with minimal energy consumption.
