Membrane:
Separation membranes can be seen as a barrier for separating two phases and as a selective transfer substance. It can be solid, liquid or gaseous, and the vast majority of separation membranes currently in use are solid-state membranes. A membrane can exist between two fluids or be attached to the micropores of a support or carrier, and the membrane thickness is much smaller than its specific surface area.
Membrane filter:
The method of separating, purifying and concentrating two-component or multi-component solutes and solvents with a specially manufactured membrane (separation membrane) with selective permeation properties under the impetus of external force is collectively referred to as membrane separation method.
Features of membrane separation:
1. There is no phase change in the membrane separation process, so the efficiency of energy conversion is high.
2. The membrane separation process is carried out at room temperature, because it is especially suitable for heat-sensitive materials.
3. Simple installation, simple operation, easy control and maintenance, and high separation efficiency.
Application areas:
1. Chemical and dye industries
2. Food and beverage industry
3. Pharmaceutical and bioengineering
4. Air filtration
5. Water treatment
