ULP-4040 low pressure RO membrane

ULP-4040 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 150psi(1.05MPa) 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≤2,000ppm, Salt content≤2000us/cm), such as the treatment of surface water, underground water, tap water, and municipal water for Foodstuff processing, Pharmaceutical production......
