LANXESS Lewabrane Seawater RO Membranes

LANXESS Lewabrane Seawater Reverse Osmosis Membranes

LANXESS LEWABRANE SEAWATER RO MEMBRANES are designed for seawater applications with elements that provide low energy usage, great fouling resistance, and high rejection of unwanted ions. These membranes are known for their highly durable and cross-linked separating layer that is suitable for applications that consist of high salinity, and high pressure.

Pure Aqua has over two decades of experience as a world-wide supplier of Seawater Reverse Osmosis Membranes from LANXESS which are designed to over perform the operational standards for seawater desalination, including delivering high rejection and high flow rate. 

The Lewabrane® RO S type is a Reverse Osmosis (RO) spiral wound membrane element for seawater desalination. The chemistry of this membrane is a higher cross-linking of the polyamide layer which improves the mechanical and chemical stability of the thin barrier layer for more durability and stable rejection of mixed ion salt solutions and organic periods.

The Lewabrane® RO S type exceeds the performance standards for desalination and is offered in high rejection (HR) and high flow (HF) types.

Three sizes are available:  RO S400 -  RO S440 -  RO S085

The RO elements RO S400 and RO S440 have a standard length of 40 inches (1,016 mm) and a diameter of 8-inches (201 mm) suitable for use within standard RO membrane equipment. The product family also includes a 4-inch (101 mm) RO element suitable for smaller applications. All 8-inch diameter elements meet today’s industry standards for RO membrane surface area at 400 and 440 square feet per 8-inch by 40-inch element.

Key attributes of the new Lewabrane® RO S HR type:

  • Low salt passage
  • More stable salt rejection during operating lifetime
  • High rejection of critical ions

Key attributes of the new Lewabrane® RO S HF type:

  • High flow productivity
  • Low salt passage at high fluxes
  • Low energy demand
