SFD-2880 Industrial Grade UF Module DupPont Equivalent

Product Introduction

The SFD-2880 Industrial Grade Ultrafiltration (UF) Module is a next-generation solution designed for high-efficiency water treatment across municipal and industrial sectors. Engineered as a full equivalent to the Dupont/DOW SFD-2880, this UF module provides the same form, fit, and function—ensuring seamless replacement and consistent performance.

With polyvinylidene fluoride (PVDF) hollow fiber membranes, the SFD-2880 is built to endure harsh chemical environments and deliver precise filtration down to 0.03 microns. It is ideal for applications such as drinking water purification, wastewater recycling, seawater desalination pretreatment, and industrial process water treatment. The module is optimized for continuous operation, reduced downtime, and long service life, making it a smart investment for long-term filtration solutions.

Working Principle

The SFD-2880 UF module functions through a physical separation process that removes suspended solids, colloids, bacteria, and viruses. It uses an outside-in hollow fiber flow design, meaning water flows from the outer surface of the membrane to the inner core, leaving contaminants on the outside.

Operation Steps:

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

2.    Filtered water (permeate) passes through the membrane wall into the hollow fiber lumen.

3.    Contaminants like bacteria and particles larger than 0.03 microns are retained on the membrane surface.

4.    Backwashing and CIP (Chemical Cleaning in Place) cycles remove fouling and restore performance.

This mechanism ensures a consistent and energy-efficient water purification process, maintaining high recovery rates and low pressure drops over time.

FAQ

1. Is the SFD-2880 module interchangeable with the DOW SFD-2880?
Yes, it is dimensionally and functionally equivalent, making installation in existing systems simple and cost-effective.

2. What is the service life of the membrane module?
Under normal operating conditions and regular maintenance, it can last 3 to 5 years.

3. Does this module remove bacteria and viruses?
Yes, the 0.03 μm pore size effectively removes bacteria, viruses, colloids, and suspended solids.

4. What are the recommended cleaning methods?
Regular backwash (every 30–60 min) and periodic chemical CIP (e.g., using NaOH, citric acid, or NaOCl).

5. Can this UF module be used for drinking water systems?
Absolutely. It is made from food-grade PVDF and complies with global potable water safety standards.

6. Is this product suitable for high TSS (total suspended solids) wastewater?
Yes, but pretreatment such as sedimentation or coarse filtration is recommended for heavily contaminated water.

7. How is backwashing triggered?
Backwashing can be triggered by pressure differential, time control, or a combination of both.

8. Do you provide technical support or OEM services?
Yes. We offer engineering support, OEM branding, installation guidance, and full documentation.
