Nanofiltration (NF) Elements

TRANSFILM™ Nanofiltration(NF) Elements can separate organics and salts from water and increase permeability while offering superior salt rejection They significantly reduce operating costs and procides optimum hardness rejection for softening applications and the removal of pesticides,bacteria or viruses.TRANSFILM™ Nanofiltration(NF) Elements are designed to provide high rejection of natural organic materials and moderate rejection of total hardness,while offering energt and cost savings.

Suitable for:

· removing total organic carbon(TOC) and trihalomethane(THM) Precursors.
· 50%-90% salt rejection with Ultra-Low-Pressure operations,increased energy savings,and significantly lower installation and operating costs.
· various operating conditions with 4° and 8° elements.

Notice

1.Permeate flow rate s for individual elements may vary ±15%
2.Membrane active areas may vary ±4%
3.Stabilized salt rejection is generally achieved after continuous using for 24-18 hours,which depend on feed water qualities and operating conditions
