ULP-8040 membrane elements are spiral wound, composite polyamide membrane elements for Brackish Water treatment. These membranes are characterized by a Low operating feed pressure, normally is 150 psi (1.05 MPa) and result in higher salt rejection rate (especially good for removing TOC, SiO2, etc.), above 99.1%. These membranes are designed for industrial water treatment applications (NaCl ≤2,000 ppm, Salt content ≤2000 µs/cm), such as the treatment of surface water, underground water, tap water, and municipal water for Foodstuff processing, Pharmaceutical production.
