Lewabrane RO S400 HR, 8”x40” High Rejection Sea Water Membrane
The Lewabrane® RO S400 HR membrane is characterized by an extremely durable, highly cross-linked polymeric separating layer suitable for high salinity, high pressure applications. The Lewabrane® RO S400 HR membrane element is recommended for single pass applications where stable salt rejection performance during the expected operating lifetime is an important consideration.
The Lewabrane RO S400 HR elements were designed for single pass seawater desalination plants where a high rejection is necessary.
Seawater (S) High rejection (HR) membranes provide the highest salt rejection and the best permeate water quality.
Key attributes of the new RO S HR type:
Low salt passage
More stable salt rejection during operating lifetime
High rejection of critical ions
High rejection type (HR) for the best permeate quality
Salt Rejection: 99.8%.
Permeate Flow: 6,500 gpd (24.6 m³/day).
Membrane Area: 400 ft².
Diameter/Length: 8/40 inch.
Feed Spacer Thickness: 31 mil.
Test conditions: 32,000 mg/l NaCl, 55.2 bar (800 psi), 25 °C (77 °F), pH 8, recovery rate 8%.
