Metal Membranes

‌Working Principle of Metal Membranes





Metal membrane filtration is driven by pressure, where large particles in the material are trapped on the surface of the filter element, forming a filter cake. The clean fluid passes through the filtration layer and moves on to the next stage. This method effectively filters or purifies fluids, particularly in environments that involve high temperatures or strong corrosive conditions.




Key Features:






Oxidation and Corrosion Resistance: Metal membranes have excellent chemical stability, making them highly suitable for harsh corrosive environments.

High Temperature Resistance: They can operate reliably at temperatures up to 900°C, making them ideal for high-temperature filtration applications.

Uniform Pore Size Distribution: The membrane's uniform pore distribution ensures consistent separation performance and high filtration precision.

High Porosity: With a high porosity rate, metal membranes offer large filtration capacity with a smaller required filter area, suitable for large-scale filtration.


Long Lifespan: Metal membranes possess high mechanical strength, with excellent resistance to pressure and impact, allowing for stable long-term operation.
