SN-UF-0860N Ultrafiltration Membrane for Coal Chemical Water Treatment Replacement

Introduction

Industrial wastewater treatment is a critical challenge for factories and processing plants worldwide. Strict environmental regulations and the increasing need for water reuse demand efficient, cost-effective filtration solutions. Ultrafiltration (UF) membranes have emerged as a leading technology for treating industrial wastewater, offering superior filtration performance, durability, and operational efficiency.

As a Chinese manufacturer specializing in ultrafiltration membranes and filtration systems, we take pride in producing high-quality UF membranes at competitive prices. Our in-house production capabilities allow us to maintain strict quality control while offering fast lead times and customized solutions to meet diverse industrial needs.

In this article, we explore how ultrafiltration membranes work in industrial wastewater treatment, their key benefits, and why our factory is the ideal partner for your filtration needs.

How Ultrafiltration Membranes Works

Ultrafiltration is a pressure-driven membrane filtration process that removes suspended solids, bacteria, viruses, colloids, and macromolecules from water. UF membranes have pore sizes ranging from 0.01 to 0.1 microns, making them highly effective in separating contaminants while allowing clean water to pass through.

Key Applications in Industrial Wastewater Treatment

1. Removal of Suspended Solids & Oil Emulsions

Industries such as petrochemical, food & beverage, and metal processing generate wastewater containing oils, greases, and fine particles. UF membranes efficiently separate these contaminants, ensuring compliance with discharge regulations.

2. Textile & Dye Wastewater Treatment

Textile effluents contain dyes, chemicals, and organic pollutants. UF membranes help decolorize and purify wastewater, enabling reuse in production processes.

3. Electroplating & Heavy Metal Removal

Wastewater from electroplating contains heavy metals (e.g., chromium, nickel, zinc). UF membranes work alongside other processes (e.g., reverse osmosis) to ensure safe disposal or recycling.

4. Pulp & Paper Industry Effluent Treatment

UF membranes remove lignin, pigments, and organic compounds, reducing chemical oxygen demand (COD) and biological oxygen demand (BOD) in paper mill wastewater.

5. Landfill Leachate Treatment

Landfill leachate contains high levels of organic pollutants and ammonia. UF pretreatment improves downstream processes like reverse osmosis (RO) or biological treatment.

Advantages of Our Ultrafiltration Membranes

1. High Filtration Efficiency & Consistent Performance

Our UF membranes provide >90% removal efficiency for suspended solids, bacteria, and macromolecules.

They operate at low pressure (1-5 bar), reducing energy costs compared to traditional filtration methods.

2. Cost-Effective Manufacturing & Competitive Pricing

As a direct factory producer, we eliminate middlemen, offering lower prices without compromising quality.

Our automated production lines ensure consistent membrane quality at scale.

3. Fast Production & Short Lead Times

Many competitors rely on outsourcing, leading to delays. We control production from raw materials to finished products, ensuring quick delivery (typically 2-4 weeks).

Customized solutions (e.g., different pore sizes, materials, and configurations) are available with minimal waiting time.

4. Durability & Long Service Life

Our UF membranes are made from PVDF (polyvinylidene fluoride) or PES (polyethersulfone), ensuring chemical resistance and mechanical strength.

They withstand harsh industrial wastewater conditions, including high turbidity and fluctuating pH levels.

5. Easy Maintenance & Low Operating Costs

Backwashable and chemically cleanable design extends membrane lifespan.

Modular systems allow for easy replacement and scalability.

Q&A

Q: What contaminants does UF remove best?

A: Bacteria, viruses, colloids, and suspended solids.

Q: Can UF remove dissolved organic matter?

A: Only larger organic molecules (e.g., proteins), not small dissolved organics.

Q: How often is backwashing needed?

A: Typically every 30–90 minutes, depending on feed water quality.
