Our Nanofiltration (NF) Spiral Wound Membrane Elements are engineered for selective separation of divalent ions, organic compounds, and color substances while maintaining high water permeability. Manufactured using high-performance piperazine polyamide membranes, these elements provide an ideal balance between reverse osmosis and ultrafiltration.

Designed for industrial separation applications, NF membranes are widely used in water softening, wastewater reuse, dye removal, and resource recovery.

• High divalent ion rejection
• Excellent organic removal efficiency
• Lower operating pressure than RO
• High permeate flux
• Stable chemical resistance
• Multiple feed spacer configurations

• Water softening
• Dye wastewater treatment
• Heavy metal removal
• Precious metal recovery
• Food concentration
• Chemical separation
• Industrial wastewater reuse
