FilmTec™ LiNE-HDR HP Element
FilmTec™ LiNE-HDR HP element is a high-performance nanofiltration membrane engineered for lithium stream purification in Direct Lithium Extraction (DLE) applications, particularly high-hardness and chloride-rich brines. Its advanced membrane chemistry delivers exceptional lithium-to-divalent cation selectivity, effectively removing impurities such as calcium and magnesium while maintaining high lithium passage and minimizing lithium loss. Optimized for operation above 400 psi, FilmTec™ LiNE-HDR HP element helps increase lithium recovery, improve process efficiency, and reduce energy consumption, providing reliable, long-lasting performance in demanding lithium production environments.
Uses
- Lithium stream purification in chloride-rich brine mining from salars, salt lakes, geothermal brine, oilfield produced water, etc.
- Specifically designed for high-hardness brines, such as pre-concentrated DLE sorbent eluent streams, to achieve an effective balance between hardness removal, lithium recovery, and energy consumption.
Advantages
- High lithium to divalent cation selectivity over a wide operating pH range enabling impurity removal from direct lithium extraction (DLE) brine streams.
- Improved efficiency over FilmTec™ LiNE-HDR element when operating above 400 psi.
- State-of-the-art membrane chemistry delivering superior lithium passage for typical chloride-rich lithium brine streams, with negligible or no lithium mass loss in high-recovery systems.
- High productivity membrane allowing for increased water and lithium mass recovery and/or reduced energy consumption.
- Expertly designed and optimized membrane chemistry providing reliable performance and sustained operational longevity.
- Engineered element construction helps to reduce the operational challenges associated with fouling.
