Persalt (PMNF) nanofiltration elements effectively reject divalent ions, organics, color, viruses, and bacteria while allowing for the passage of more monovalent ions.
The PMNF1 and PMNF2 membranes are designed for softening and applications requiring the removal of color and organics. These elements utilize low-pressure drop (LPD) technology and operate at ultra-low pressures.
Persalt has developed new applications for PMNF elements in wastewater treatment, specifically for landfill leachate, by removing organics from the leachate stream before discharge.
The Persalt NANO-400SR and NANO-440SR membranes are specifically designed to remove sulfate from seawater. Offshore platforms inject seawater into oil wells to enhance petroleum production. These elements reject 99.8% of sulfate while allowing monovalent ions, such as chloride and sodium, to pass through, thus preventing scaling and reservoir souring. Monovalent ions are essential for maintaining clay stability in the wells.
