The Lewabrane ® Reverse Osmosis Lanxess B400 HF membrane are spiral wound, composite polyamide membrane elements designed for industrial water treatment applications, such as the treatment of brackish and low salinity waters for primary demineralization in boiler water and process water applications.
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 B400 HF membrane helps reduce dissolved salts and minerals from feedwater through reverse osmosis technology. It is commonly used as part of treatment systems that require lower dissolved mineral content for process and utility water applications.
Typical uses include:
- Boiler feed water pretreatment
- Industrial process water treatment
- Brackish water reverse osmosis systems
- Demineralization applications
- Manufacturing facilities
- Industrial utility water systems
- Commercial water treatment plants
How It Works
- The Lanxess B400 HF RO membrane uses spiral-wound composite polyamide membrane technology to separate dissolved salts and minerals from feedwater.
- During the reverse osmosis process, pressurized water passes through the membrane layer while dissolved substances are reduced from the water stream.
- The treated permeate water is collected for industrial applications, while concentrated water is discharged according to the RO system design.
