3 Terms and definitions
The following terms and definitions defined in GB/T 20103-2006 apply to this document. For ease of use, the following is repeated
Some terms and definitions in GB/T 20103-2006.
3.1
Membrane distillation membranedistilation; MD
Using the difference in temperature on both sides of the microporous membrane, the aqueous solution in contact with the hot side vaporizes on the surface of the membrane, and the generated water vapor passes through the membrane pores
It is transferred to the cold side of the membrane and condenses into water to complete the separation process.
Note. The methods include direct contact, air interval, decompression or gas purging.
[GB/T 20103-2006, definition 6.2.6]
3.1.1
Direct contact membrane distillation directcontactmembranedistilation
The aqueous solutions on the raw material side and the permeate side are in direct contact with the surfaces on both sides of the porous membrane, and the generated water vapor is transferred to the permeate side through the membrane pores.
And condenses into water, thus completing the separation process.
3.1.2
Air gap membrane distillation airgapmembranedistilation
There is an air gap between the condensing surface and the surface of the membrane on the permeate side. After passing through the air gap, the steam condenses into water on the condensing surface to complete the separation.
The process of leaving.
3.1.3
Gas purging membrane distillation sweepgasmembranedistilation
Use inert gas to blow the steam on the permeate side out of the module and condense it into water outside to complete the separation process.
