Products Description
- Occupying the performance spectrum between ultrafiltration and reverse osmosis, this membrane achieves a finely calibrated trade‑off of flux and selectivity, fitting processes calling for purification as well as preservation of high‑value components.
- Nanofiltration requires fairly low operating pressure and energy input, making it a cost‑saving choice for softening, organics removal and partial desalination in hygienic process environments.
Product Features
- Optimized polyamide membrane layer enhances salt rejection and flux stability
- Enhanced anti‑fouling properties guarantee extended operational lifespan
- Reinforced anti‑fouling characteristics secure extended in‑service durability
