ULP-8040 membrane element is a helically wound composite polyamide membrane element for brackish water treatment. These membranes are characterized by low operating feed pressures, typically 150psi (1.05MPa), resulting in higher salt removal (especially suitable for removal of TOC, SiO2, etc.), above 99.1%. These membranes are designed for industrial water treatment applications (NaCl≤2000ppm, salt content≤2000us/cm), such as treatment of surface water, groundwater, tap water and food processing, municipal water for pharmaceutical production...
