DuPont IntegraPac™ IP-51 Strongly fouling-resistant ultrafiltration membranes Equivalent

Introduction

Ultrafiltration membrane is one of the types of membrane separation, which is between microfiltration and nanofiltration. It can purify, separate and concentrate solutions. In the process of using ultrafiltration membrane technology for water filtration, it can form a water quality filtration effect with unbalanced pressure, which has a good filtration effect while ensuring that the clean water on both sides of the membrane can flow freely without being affected, and finally effectively remove particles, colloids and various organic substances in the water, such as algae, bacteria, aquatic organisms, etc.

The Growing Demand for Advanced Filtration Solutions

With increasing environmental regulations and the urgent need for water conservation, industries worldwide are turning to ultrafiltration membranes as a versatile and sustainable solution. Our UF technology is specifically engineered to:

1. Remove contaminants as small as 0.01 microns, including bacteria, viruses, and colloidal particles.

2. Enhance water reuse by enabling high recovery rates in industrial wastewater treatment.

3. Protect downstream equipment such as reverse osmosis (RO) membranes and ion exchange systems from fouling and scaling.

Unlike conventional filtration methods, our DuPont IntegraPac™ IP-51 Strongly fouling-resistant ultrafiltration membranes Equivalent offer longer service life, lower energy consumption, and minimal chemical usage, making them an economically and environmentally sound choice.

Why Our Ultrafiltration Membranes Stand Out

1. Unmatched Manufacturing Expertise

As a factory-direct manufacturer, we maintain complete control over every stage of production—from polymer formulation to final module assembly. This allows us to:

Optimize membrane performance for specific industrial applications.

Reduce lead times to as little as 2–3 weeks for standard orders.

Offer competitive pricing without compromising on quality.

2. Superior Material Science

Our UF membranes are crafted from high-grade PVDF (Polyvinylidene fluoride) and PES (Polyethersulfone), ensuring:

Exceptional chemical resistance, even in aggressive wastewater environments.

High mechanical strength, reducing the risk of fiber breakage during operation.

Hydrophilic surface properties, which minimize fouling and simplify cleaning.

3. Customizable Solutions for Diverse Industries

We understand that no two industrial applications are the same. That’s why we offer:

Tailored membrane configurations (hollow fiber, capillary, or flat-sheet).

Custom pore sizes and flux rates to match specific feed water conditions.

Integration with existing treatment systems, including MBR (Membrane Bioreactor) and ZLD (Zero Liquid Discharge) setups.

Key Applications of Our Ultrafiltration Membranes

1. Pretreatment for Reverse Osmosis (RO) and Nanofiltration (NF) Systems

Challenge: RO/NF membranes are highly susceptible to fouling from suspended solids and organic matter.

Our Solution: UF pretreatment removes >99.9% of turbidity and pathogens, significantly extending RO membrane life and reducing maintenance costs.

Industries Served: Power plants, semiconductor manufacturing, food and beverage production.

2. Industrial Wastewater Treatment and Recycling

Challenge: Many industries struggle with high water consumption and stringent discharge limits.

Our Solution: Our UF systems enable up to 90% water recovery, allowing facilities to reuse treated effluent in cooling towers, boilers, or process lines.

Success Story: A chemical plant reduced freshwater intake by 70% after implementing our UF-based recycling system.

3. Process Water Purification

Challenge: Industries like pharmaceuticals and electronics require ultra-pure water free of particulates and microbes.

Our Solution: UF membranes provide consistent, high-quality water with low SDI (Silt Density Index), ensuring compliance with strict purity standards.

FAQs

Q: What causes UF membrane fouling?

A: Accumulation of organics, biofilms, colloids, or inorganic scaling (e.g., CaCO₃) on the membrane surface.

Q: What is MWCO in UF?

A: Molecular Weight Cut-Off: The smallest molecular weight (Da) a membrane retains (e.g., 10–500 kDa).

Q: Can UF operate without electricity?

A: No — pressure-driven filtration requires pumps, but gravity-fed systems (e.g., in emergency filters) exist at small scales.
