- NF Membrane Sheet: Made of polyamide (PA) thin-film composite material with excellent selectivity and chemical resistance.
- Feed Spacer: Ensures uniform feed distribution and reduces concentration polarization.
- Permeate Carrier Layer: Supports stable water flow and minimizes pressure loss.
- Module Housing: Typically FRP or PVC, providing durability and corrosion resistance.
- End Caps & Connectors: Sealed design to ensure easy installation and reliable operation.
- Selective Ion Rejection: Removes multivalent ions (Ca²⁺, Mg²⁺, SO₄²⁻) while allowing partial passage of monovalent ions.
- High Organic Removal: Effectively removes color, organic matter, and macromolecular contaminants.
- Low Operating Pressure: Achieves high permeate flux under lower pressure compared with RO membranes.
- Energy Saving: Reduced power consumption with stable operation and high recovery rate.
- Excellent Chemical Stability: Resistant to oxidation and compatible with standard cleaning chemicals.
- Anti-Fouling Design: Smooth membrane surface minimizes scaling and biofouling.
- Long Service Life: Durable polyamide composite structure ensures long-term performance stability.
- Flexible Integration: Fits standard 4040 and 8040 membrane housings for easy system retrofitting.
- Water Softening: Selective removal of hardness ions (Ca²⁺, Mg²⁺).
- Drinking Water Purification: Reduction of organic matter, color, and odor.
- Industrial Process Water: Pre-treatment for RO systems or high-quality process water production.
- Wastewater Reuse: Removal of organic and hardness contaminants in reclaimed water.
- Food & Beverage Industry: Concentration and purification of juices, dairy, and process water.
- Textile and Dyeing Industry: Color removal and reuse of process water.
