SFP-2660 Industrial Grade UF Module DupPont DOW Equivalent

Product Introduction

The SFP-2660 Industrial Grade UF Module is a high-performance ultrafiltration (UF) solution engineered for superior water purification in a wide range of industrial and municipal applications. Designed as a direct replacement for the DOW/DuPont SFP-2660 model, this module is fully compatible in size, configuration, and performance—making it an ideal choice for system retrofits, upgrades, and new installations alike.

Constructed with advanced hollow fiber membranes using polyvinylidene fluoride (PVDF), this module offers exceptional resistance to chemical, thermal, and mechanical stress. Whether used for reverse osmosis pretreatment, wastewater reuse, or process water purification, the SFP-2660 delivers reliable, cost-effective filtration with long operational life and minimal maintenance needs.

Working Principle

Ultrafiltration is a pressure-driven membrane separation process that uses hollow fiber membranes to remove suspended solids, microorganisms, colloids, and high molecular weight organic matter from water. The SFP-2660 module functions using an “outside-in” filtration mode, allowing particles larger than 0.03 microns to be retained on the membrane surface while clean water permeates through the membrane into the fiber lumen.

Filtration Stages:

1.    Feed water enters the module and flows across the membrane surface.

2.    Contaminants are captured on the outside of the hollow fibers.

3.    Treated water passes through the membrane pores and exits via the permeate port.

4.    Periodic backwashing and chemical cleaning are performed to restore membrane performance and prolong lifespan.

This filtration method maintains stable output even with variable raw water quality, while its design minimizes fouling and energy consumption.

Technical Parameters

Applications

The SFP-2660 UF Module is built for use in multiple industries and municipal systems. Its wide compatibility and reliability make it a go-to solution for:

🏭 Industrial Process Water

Removes fine particles, organic matter, and biological load from raw water, improving water quality for manufacturing and rinsing processes.

💧 RO System Pretreatment

Significantly reduces silt density index (SDI), particulate matter, and biofouling risks for downstream reverse osmosis membranes.

♻️ Wastewater Recycling

Used in MBR systems and industrial wastewater plants to filter solids and enable water reuse or environmental discharge compliance.

🏙 Municipal Water Treatment

Provides bacteria- and virus-free potable water through ultrafiltration in public supply systems and decentralized treatment units.

🧪 Pharmaceutical & Food Industry

Ensures high-purity water for formulation, washing, and production in industries with strict water quality standards.

🌊 Seawater & Brackish Water Desalination

Protects RO membranes by serving as a robust pre-filtration barrier in saline water treatment plants.

FAQ

1. Is your SFP-2660 module a genuine DOW/DuPont product?
No, it is a high-quality equivalent module designed to match DOW/DuPont SFP-2660 specifications in every aspect—dimension, performance, and compatibility.

2. Can I install this module in my existing UF system that uses DOW SFP-2660?
Yes. The module is engineered for plug-and-play compatibility, with the same end caps and filtration area.

3. What is the recommended operating pressure for this module?
The standard operating pressure is 0.1–0.3 MPa. Do not exceed 0.4 MPa to avoid membrane damage.

4. How long will the membrane last?
Under normal conditions, the lifespan ranges from 3–5 years with proper maintenance and cleaning cycles.

5. Does the module support chemical cleaning (CIP)?
Yes, it is compatible with standard alkaline, acidic, and oxidizing agents like NaOH, citric acid, and sodium hypochlorite.

6. How often should backwashing be performed?
Backwash every 30–60 minutes during continuous operation, depending on feed water quality and fouling rate.

7. What kind of water can be treated with this module?
Suitable for surface water, groundwater, seawater (pre-treatment), municipal water, and light industrial wastewater.
