4 inch Seawater Reverse Osmosis Membranes
The RO S type is the new Reverse Osmosis (RO) spiral wound element for Seawater Desalination.
The Lewabrane® RO S Type membranes are characterized by an extremely durable, highly cross-linked polymeric separating layer suitable for high salinity, high pressure applications. The Lewabrane® RO S HR type membrane elements are recommended for single pass applications where stable salt rejection performance during the expected operating lifetime is an important consideration. Seawater (S) High rejection (HR) membranes provide the highest salt rejection and the best permeate water quality.
