PSI MEMBRANE® UNF series of Loose Nanofiltration or Compact Ultrafiltration Membrane element incorporating innovative Thin Film Nanocomposite (TFN) technology, the UNF series features nano-level, ultra-thin hydrophilic coating technology that offers excellent anti-fouling performance. These membranes deliver flux rates four times higher than traditional TFC membranes while operating at least 50% lower pressure. They are the perfect replacement for conventional TFC membranes.
n Precision at its Best Higher: Offers multiple precise cutting molecules, tailored to meet specific customer requirements.
n Unmatched Efficiency: Achieves product flow rates up to four times higher than imported brands, significantly reducing energy consumption and project costs.
n Superior Selective Separation:Boasts ultra-high selectivity, effectively removing most colloidal iron, colloidal silicon, humic acid, and other dissolved organic matter (DOM) while allowing the passage of inorganic single and bivalent ions.

1. Feed spacer thickness and permeate flow rate are respectively based on the following standard test conditions: Pure water with a conductivity of less than 10 μS/cm, a 200 ppm solution of polyethylene glycol (PEG) with the corresponding molecular weight cut-off (e.g., UNF2000 corresponds to a PEG molecular weight cut-off of 2000 Da), 0.48 MPa, 77 ℉ (25 ℃), and 15% recovery. 2. The variation range of permeate flow rate is +/-15%. |
