FTM is an asymmetric membrane made of high purity special materials by a special process at 2400°C. It is a multi-channel membrane with a porous support base and an intermediate layer and an active membrane layer.
From outside to inside, they are porous support base, intermediate layer, and active membrane layer.
This technology has several advantages:
1. High membrane porosity
The FTM brine refining membrane, characterized by its high porosity exceeding 45%, facilitates lower pressure loss during filtration, enhancing liquid flux capacity and rate. With a filtration pore size of 50nm, it achieves a flux over 1,000L/m2.h for saturated sodium chloride brine.
2. Excellent chemical stability
Exhibiting robust resistance to strong acids, alkalis, thermal stability up to 800°C, superior oxidation stability, and extended service life, this material ensures stable operation in challenging environments including high-temperature, high-concentration phosphoric acid, sulfuric acid, hydrofluoric acid, and alkaline conditions, where Al2O3ceramic membranes can't be used.
3. High filtration accuracy
The average pore size of FTM inorganic membranes ranges from 10-50 nm, providing precise filtration for a wide range
of applications.
4. Small footprint and low operating energy consumption
As the flux of FTM brine refining membrane is larger, at equal production capacity demand, the required membrane area is halved compared to Al2O3 ceramic membrane, reducing equipment footprint and investment. This area reduction also cuts circulating flow, enabling over 50% energy savings and substantial cost reduction in filtration operations.
