Lewabrane RO S085 HF, 4”x40” High Rejection Seawater Membrane
The Lewabrane® RO S084 HR 4040 seawater membrane is characterized by an extremely durable, highly cross-linked polymeric separating layer suitable for high salinity, high pressure applications. The Lewabrane® RO S084 HR 4040 seawater 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 S084 HR 4040 seawater 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: 1,380 gpd (5.2 m³/day).
Membrane Area: 85 ft².
Diameter/Length: 4 inch / 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%.
Application: Lewabrane® RO S084 HR 4040 is a standard size seawater membrane, widely used for watermakers, desalinators, seawater desalination systems, marine (yacht and boat), Navy and martime applications.
Commonly used in on-board Watermakers to create drinking water from seawater for yachts, boats, and cruise ships..
