Nanofiltration (NF) Systems
General Discription
Advanced Water Purification Beyond RO
Aquatech Plus offers cutting-edge Industrial Nano filtration (NF) Systems that go beyond traditional reverse osmosis. NF systems are ideal for industries seeking efficient removal of hardness, foul taste, odor, pesticides, and organic compounds, while retaining beneficial minerals.
Key Advantages:
- ✅ Lower Water & Energy Consumption than RO
- ✅ Superior Hardness & Bivalent Ion Removal (e.g., calcium, magnesium, uranium, radium)
- ✅ Less Maintenance & Fouling RO or softeners
- ✅ Selective Mineral Retention with high contaminant rejection
- ✅ Efficient Filtration of Microorganisms & Organics
Designed using advanced nanotechnology and 3D process modeling, our NF systems ensure custom-built performance and reliability for high TDS water treatment across industries.
