High flux and superior performance in eliminating monovalent and divalent salts are offered by SM NF90 series NF membranes. It removes natural organic chemicals and organic compounds with a high clearance rate, including pesticides, herbicides, and THM precursors. During the water treatment process, organic matter, turbidity, color, and hazardous compounds can all be successfully removed from the water in addition to lowering its hardness. It can also retrieve tiny molecular organics and precious multivalent salts. It can efficiently remove contaminants or recover useful compounds at very low operating pressure and requires very little net driving pressure. The technology operates at a minimal cost and energy usage.
Remarks of NF Membrane

The individual element's permeate flow may differ by up to 15% from the specified value.
Guaranteed active membrane area within ±4%.
Stabilized salt rejection can usually be attained within 24-48 hours of continuous use, contingent on the properties of the feedwater and the operating environment.
