Introduction
In an industry where premium ultrafiltration (UF) membranes from global brands like DuPont, Hydranautics, Mann+Hummel, and Inge often come with a steep price tag, LEFILTER has emerged as a game-changer. With 16 years of expertise in manufacturing high-performance DuPont DOW SFP/SFD2860 replacement UF membranes, LEFILTER offers cost-effective alternatives without compromising quality. Headquartered in Xinxiang, Henan, the company operates its own factory, ensuring fast production cycles, competitive pricing, and reliable supply—key advantages that make it a preferred partner for water treatment projects worldwide.
The Power of DuPont DOW SFP/SFD2860 replacement Ultrafiltration in Modern Water Treatment
Ultrafiltration membranes play a critical role in water purification by efficiently removing suspended solids, bacteria, viruses, colloids, and other contaminants while maintaining low energy consumption. UF technology is widely applied in:
1. Drinking Water Purification – Providing safe, clean water by eliminating pathogens and impurities.
2. Industrial Water Treatment – Ensuring high-quality process water for manufacturing, power plants, and chemical industries.
3. Seawater Desalination Pretreatment – Reducing fouling and extending the lifespan of reverse osmosis (RO) systems.
4. Wastewater Treatment & Reuse – Enabling sustainable water recycling in municipal and industrial applications.
Despite its effectiveness, the high cost of branded UF membranes has been a barrier for many projects. LEFILTER bridges this gap by delivering equally reliable yet more affordable alternatives, making advanced water treatment accessible to a broader market.

LEFILTER’s Competitive Edge: Quality, Speed, and Affordability
1. Factory-Direct Production Ensures Lower Costs & Faster Delivery
Unlike distributors or trading companies, LEFILTER controls the entire production process—from raw material sourcing to final quality inspection. This vertical integration allows the company to cut unnecessary middleman costs and offer prices 30-50% lower than premium brands while maintaining stringent quality standards.
Additionally, with optimized manufacturing efficiency, LEFILTER guarantees shorter lead times—crucial for clients facing tight project deadlines. Whether for small-scale applications or large industrial installations, the company can fulfill urgent orders without delays.
2. High-Performance Membrane Technology at a Fraction of the Cost
LEFILTER’s DuPont DOW SFP/SFD2860 replacement UF membranes are designed to match—and in some cases, exceed—the performance of leading brands. Key features include:
High Filtration Accuracy (0.01-0.1 microns) – Effectively removes bacteria, viruses, and colloidal particles.
Strong Chemical Resistance – Withstands frequent backwashing and CIP (cleaning-in-place) processes.
Long Service Life – Durable membrane materials ensure 5-8 years of stable operation with proper maintenance.
Low Energy Consumption – Optimized flow design reduces operational costs.
These membranes have been successfully deployed in drinking water plants, industrial wastewater treatment, and seawater desalination pre-filtration, proving their reliability in demanding environments.
3. Custom Solutions for Diverse Applications
Understanding that one size does not fit all, LEFILTER provides tailored UF membrane solutions based on specific water quality and operational requirements. Whether clients need:
Hollow Fiber UF Modules for municipal water treatment
Spiral-Wound UF Elements for industrial RO pretreatment
Submerged UF Systems for wastewater reuse
LEFILTER’s engineering team collaborates closely with customers to design, test, and optimize the most efficient filtration setup.
Success Stories: LEFILTER Membranes in Action
Case 1: Municipal Drinking Water Plant Upgrade
A regional water treatment plant in Southeast Asia replaced its expensive imported UF membranes with LEFILTER’s alternative, achieving comparable effluent quality at 40% lower cost. The plant reported stable flux rates and reduced maintenance frequency, validating the membranes' durability.
Case 2: Industrial Wastewater Recycling for a Textile Factory
A textile manufacturer in India adopted LEFILTER’s UF system to treat and reuse dyeing wastewater, significantly cutting freshwater consumption. The project’s quick turnaround (from order to commissioning in 6 weeks) was made possible by LEFILTER’s fast production and logistics support.

Looking Ahead: Expanding Global Reach
With growing demand for cost-efficient, high-performance water treatment solutions, LEFILTER is scaling up production and strengthening its international distribution network. The company is actively seeking partnerships with engineering firms, system integrators, and water treatment specialists to bring its affordable UF technology to more markets.

Ultrafiltration membrane Q&A
Q1: What is the function of ultrafiltration membrane?
A: It is used to separate macromolecules (such as bacteria, viruses, colloids) in water and allow small molecules (water, salts) to pass through to achieve purification or concentration.
Q2: Where are ultrafiltration membranes used?
A: Main applications:
1. Drinking water purification
2. Wastewater treatment (MBR process)
3. Food industry (milk, juice filtration)
4. Medicine (protein separation, hemodialysis)
Q3: How to prevent ultrafiltration membrane clogging?
A:
1. Pre-treat raw water (filtration, flocculation)
2. Regular backwashing
3. Chemical cleaning (alkali washing to remove organic matter, acid washing to remove scale)
