DuPont DOW SFP/SFD2860 Brackish Water Purification UF Membranes Equivalent

Introduction

Ultrafiltration (UF) is a pressure-driven membrane separation process that uses the interception capacity of porous materials to separate particulate matter from fluids and dissolved components. The typical pore size of ultrafiltration membranes is between 0.01-0.1 microns, and has a very high removal rate for bacteria and most viruses, colloids, sludge, etc. The smaller the nominal pore size of the membrane, the higher the removal rate. The materials commonly used in ultrafiltration membranes are high molecular polymers, and their basic properties are mainly hydrophobic. They can be modified by hydrophilicity such as blending. The process is operated at room temperature, without phase change, and does not produce secondary pollution.

The Growing Demand for Safe Drinking Water

Access to clean and safe drinking water remains a critical global challenge. Contaminants such as bacteria, viruses, colloidal particles, and organic matter pose significant health risks, making advanced filtration technologies essential. Ultrafiltration membranes have emerged as a key solution, effectively removing impurities while ensuring high water flux and long-term reliability. However, the high cost of branded UF membranes from industry giants often limits accessibility, particularly for small to medium-sized water treatment projects in developing regions.

LEFILTER addresses this gap by manufacturing high-performance DuPont DOW SFP/SFD2860  Brackish Water Purification UF Membranes Equivalent that match—and in some cases exceed—the quality of leading brands at a fraction of the cost. With an in-house production facility in Xinxiang, Henan, LEFILTER leverages advanced manufacturing techniques, strict quality control, and economies of scale to deliver cost-efficient UF solutions without compromising performance.

UF Membrane: A Smart Alternative for Drinking Water Purification

DuPont DOW SFP/SFD2860  Brackish Water Purification UF Membranes Equivalent are engineered to deliver exceptional filtration performance, making them ideal for:

1. Bacteria & Virus Removal – With a pore size of 0.01-0.1 microns, LEFILTER’s UF membranes effectively block bacteria (removal rate >99.99%) and viruses (removal rate >99.9%), ensuring microbiologically safe drinking water.

2. Colloidal & Suspended Solids Filtration – The membranes efficiently remove turbidity-causing particles, delivering crystal-clear water with turbidity levels below 0.1 NTU.

3. Chemical-Free Purification – Unlike traditional disinfection methods that rely on chlorine or ozone, UF provides physical filtration without altering water chemistry, making it safer for long-term consumption.

4. High Water Recovery & Low Energy Consumption – LEFILTER’s membranes are designed for optimal permeability (typically 150-300 LMH/bar), reducing operational costs while maintaining high throughput.

Key Advantages

1. Cost-Effective Without Compromise

LEFILTER’s membranes are priced 30-50% lower than DuPont, Hydranautics, and other premium brands, making advanced water treatment more accessible.

Despite the lower cost, the membranes undergo rigorous testing to ensure durability, chemical resistance, and consistent performance.

2. Fast Production & Short Lead Times

Unlike multinational suppliers with complex supply chains, LEFILTER’s centralized manufacturing in Xinxiang enables rapid production and delivery—often within 2-4 weeks, compared to the 8-12 weeks typical of global brands.

Customization options (e.g., different fiber materials, module sizes) are available to meet specific project requirements.

3. Proven Performance in Real-World Applications

LEFILTER’s UF membranes have been successfully deployed in municipal water plants, rural drinking water projects, and commercial purification systems across Asia, Africa, and Latin America.

Independent tests confirm that the membranes meet or exceed NSF/ANSI 61 and WHO drinking water standards.

Future Outlook: Expanding Global Reach with Affordable Innovation

As water scarcity and contamination concerns escalate worldwide, the demand for reliable yet economical UF solutions will continue to grow. LEFILTER is committed to advancing membrane technology while keeping costs competitive, enabling more communities and industries to adopt advanced water purification systems.
