In general, Filtration means separating two or more types of components from a fluid, and the concept of a general filter refers to separating undissolved particles (solids) from a fluid.
On the other hand, the concept of the membrane filter is much more microscopic than the concept of general filtration, and it includes a special function that enables the separation of dissolved-solids or mixed gases.
Membrane separation process is different from general filtration process
- It has semi-permeable and perm-selectivity.
- Separation/fraction is possible from Sub-Micron size to the range of molecular weight size range.
- It is possible to separate gas-gas, gas-liquid and liquid-liquid as well as liquid-gas, gas-solid separation among fluids.
GS Membrane(Gas Separation , Gas separation membrane)
It is a fiber membrane made of Polysulfone (PSF) and can be separated by using the difference in gas permeation rate to the polymer membrane.
It does not require energy for phase change and can be operated at room temperature.
The system's simplification and integration makes it possible to make the device compact.
- (For oxygen) Used for oxygen generator and oxygen water, oxygen water production
- (For nitrogen) Used for nitrogen generator
- (Dehumidification Membrane) Used to remove moisture from the air
- (Biogas Separation Membrane) Fuel Cell, City Gas, Vehicle Fuel
Advantages and disadvantages
- Advantage : Energy saving / system simplification, miniaturization / room temperature operation possible
- Disadvantage : Fewer commercialization cases / Lack of system technology
