FilmTec™ LiNE-XLE element is a low-energy, high-productivity nanofiltration membrane specifically designed for lithium brine purification in Direct Lithium Extraction (DLE) processes. It efficiently removes sulfate and other multivalent ions from high-TDS lithium brine while maintaining high lithium passage, helping producers maximize lithium recovery with minimal lithium loss. Advanced membrane chemistry and an optimized design deliver strong purification performance at lower energy consumption, while a 10% increase in active membrane area boosts productivity and can reduce the number of elements required in a system. The result is a more efficient, cost-effective brine treatment solution that supports simplified system design and reliable operation.
