The Osmotics NF 90 Nanofiltration Membrane is engineered for softening, colour reduction, and selective removal of multivalent ions — offering performance comparable to the trusted Toray NE 90 NF series. Its advanced thin-film composite design ensures excellent rejection of hardness-causing ions like calcium and magnesium, while allowing controlled passage of monovalent salts, making it ideal for applications where partial desalination is desired.

NF 90 is widely used across municipal, commercial, and industrial systems where high-purity water is required but complete RO desalination is unnecessary. Its ability to remove organic matter, tannins, colour, pesticides, and high-molecular contaminants makes it a versatile and energy-efficient treatment option.

⭐ Key Features & Benefits

✔ Hardness & Colour Removal

Effectively removes calcium, magnesium, iron complexes, humic substances, and organic colour bodies.

✔ Partial Desalination

Offers moderate salt rejection while achieving high rejection of divalent ions like sulfate and hardness.

✔ High Permeate Flow (8040 Series)

Nominal 10,500–11,000 GPD, delivering higher output at lower pressure compared to RO membranes.

✔ Lower Operating Pressure

NF membranes operate typically at 6–10 bar, reducing energy cost.

✔ Organic & Micro-pollutant Removal

Excellent in removing:

• Colour (tannins)

• Turbidity

• Pesticides

• THM precursors

• Organic carbon compounds

✔ Standard 8040 Compatibility

Fits into all standard commercial & industrial 8040 pressure vessels.

📌 Typical Applications

• Softening of borewell & high-hardness water

• Colour & tannin removal from surface water

• High recovery NF systems for industrial utilities

• Pretreatment for RO plants to reduce scaling load

• Textile & dye wastewater colour removal

• Beverage & process water

• Municipal filtration and organic reduction
