Nanofiltration (NF) System: Advanced Water Purification Solutions
Understanding Nanofiltration System
At Pervel, we specialise in innovative nanofiltration systems designed to deliver superior water treatment performance. Whether for industrial, commercial, or municipal applications, our NF solutions efficiently remove impurities while optimizing energy consumption and operational efficiency.
How Nanofiltration System Works
Nanofiltration system operates on a pressure driven separation process, where water is forced through a semi-permeable membrane to remove dissolved ions and organic matter. Unlike traditional dead end filtration, Nanofiltration system utilizes cross flow filtration, allowing continuous operation with minimal clogging.
Most modern Nanofiltration system membranes feature a spiral wound design, constructed from advanced composite materials supported by a polymer substrate. This configuration ensures high efficiency, durability, and ease of maintenance – making it the preferred choice for industrial applications.
Why Choose Nanofiltration system?
Nanofiltration system bridges the gap between ultrafiltration (UF) and reverse osmosis (RO), offering a balanced solution where high salt rejection isn’t necessary. Key advantages include:
- Lower energy consumption – Operates at 50-70% lower pressure than RO, reducing operational costs.
- Selective filtration – Effectively removes divalent ions (like calcium & magnesium) while allowing some monovalent salts to pass, making it ideal for water softening.
- Versatile applications – From wastewater recycling to pesticide removal, Nanofiltration system provides tailored solutions across industries.
Key Applications of Nanofiltration system
Our Nanofiltration system is trusted in various sectors for:
✔ Water Softening – Reduces hardness while maintaining essential minerals.
✔ Heavy Metal Removal – Efficiently filters contaminants like lead, arsenic, and cadmium.
✔ Wastewater Recycling – Reclaims water in laundries, textiles, and manufacturing.
✔ Complete Removal of Nitrate & Pesticide – Secure groundwater as well as drinking supplies.
✔ Food & Pharma Production – Purifies process water while retaining critical compounds.
Nanofiltration system vs. Reverse Osmosis: What’s the Difference?
While both Nanofiltration system and RO use semi-permeable membranes, NF is less restrictive, allowing partial salt passage. Here’s how they compare:
| Feature | Nanofiltration system (NF) | Reverse Osmosis (RO) |
|---|---|---|
| Salt Rejection | 50-80% | 95-99% |
| Operating Pressure | Lower (50-70% of RO) | Higher |
| Energy Efficiency | More efficient | Less efficient |
| Best For | Softening, organics removal | Complete desalination |

NF membranes filter low-TDS water, removing organics, hardness, and multivalent ions. They are very much utilized in water treatment, food processing, and pharma industry.
If you need partial desalination, softening, or organic removal without ultra-high purity, NF is the smarter, more economical choice.
Absolutely! NF is excellent for dye removal in textiles, caustic recovery, and acid recycling, reducing waste and chemical costs.
