Lewabrane® RO S440 HR elements are spiral-wound, composite polyamide membrane elements designed for the desalination of seawater. The S440 HR membrane is characterized by an extremely durable, highly cross-linked polymeric separating layer suitable for high salinity, high pressure applications. The Lewabrane® RO S440 HR membrane element is recommended for single pass applications where stable salt rejection performance during the expected operating lifetime is an important consideration.
