Lanxess RO S400 HR Membrane
Lewabrane® RO S400 HR elements are spiral-wound, composite polyamide membrane elements designed for the desalination of seawater. The 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
Element is tested under the following conditions: applied pressure 55.2 bar (800 psi), NaCl concentration 32,000 mg/l (or when tested on a mixed solution of 32,000 mg/l NaCl and 5 mg/l Boron), operating temperature 25 °C (77 °F), pH 8 and recovery rate 8 %.
Additional Information:
- Treat RO Elements with care; do not drop the element.
- Each RO Element is wet tested, preserved in a 1% weight sodium bisulfite solution, and vacuum packed in oxygen barrier bags.
- During storage, avoid freezing and direct sunlight. The temperature should be below 35 °C (95 °F).
After Installation:
- Keep the RO Elements wet, and use a compatible preservative for storage duration longer than 7 days.
- During the inital start up, discharge the first permeate to drain for 30 min.
- Permeate back pressure should not exceed feed pressure at any time.
- The RO Elements shall be maintained in a clean condition, unfouled by particulate matter or precipitates or biological growth.
- Consider cleaning, if the pressure drop increases by 20% or water permeability decreases by 10%.
- Use only chemicals which are compatible with the membrane.
What This Membrane Is Used For
The Lanxess RO S400 HR membrane is used for seawater reverse osmosis applications where high salinity feedwater requires desalination treatment. It is designed for industrial RO systems that operate under high-pressure conditions. This membrane element is suitable for applications requiring stable salt rejection performance, including seawater desalination plants, industrial water treatment systems, and large-scale RO projects.
Compatible Systems
- Seawater reverse osmosis plants
- Industrial desalination systems
- High-pressure RO applications
- Commercial RO treatment systems
- Industrial water purification systems
- Process water treatment systems
- Large-scale desalination projects
How It Works
The Lanxess RO S400 HR membrane uses spiral-wound composite polyamide membrane technology to separate dissolved salts and minerals from seawater and high salinity feedwater. During the reverse osmosis process, pressurized feedwater passes through the membrane surface, allowing treated water to pass while reducing dissolved components from the concentrated water stream. The produced permeate water is collected for further use according to the requirements of the water treatment system.
