Product Description

High rejection Nano filtration membrane for extracting lithium from brines.

Nanofiltration membrane element can realize acid purification and recovery and metal ion concentration in the environment of high acidity. Using nanofiltration membrane technology, the salinity of salt lake original halogen is lower than 20%, and directly enters the membrane system after pre-filtration. After nanofiltration membrane treatment, it can effectively remove calcium, magnesium, sulfate and other impurities, and greatly reduce the magnesium to lithium ratio. RisingSun Membrane can provide nanofiltration membrane with high retention rate, 
which can intercept more than 95% of lithium ions in the lithium extraction wastewater from salt lake brine.





We provide spiral nanofiltration membranes with many size.

After years of research and development, We can offer different molecular weight NF membranes to meet a wide range of industiral separation processes.

Our NF5 has excellent MgSO₄ and lactose rejection,which can be used for many industry. Nanofiltration membranes overall are also able to greatly reduce levels of hardness, nitrates, sulfates, tannins, turbidity, color, TDS, and moderate levels of salt from feed water streams.
