3 Terms and definitions

The following terms and definitions defined in GB/T 20103 apply to this document. For ease of use, the following is repeated Relevant terms and definitions in GB/T 20103. 3.1 Membrane distillation membraneistilation Using the difference in temperature between the two sides of the microporous membrane, the aqueous solution in contact with the hot side is vaporized on the surface of the membrane, and the generated water vapor passes through the membrane pore. It is passed to the cold side of the membrane and condensed into water to complete the separation process. Note. The method is direct contact type, air interval type, decompression type or gas purging type. [GB/T 20103-2006, definition 6.2.6] 3.2 Hydrophobic membrane A membrane having a separation function made of a hydrophobic material. 3.3 Hydrophobic microporous membrane A hydrophobic membrane having a membrane average pore diameter of from 0.05 μm to 1.00 μm. 3.4 Maximum aperture maximumporediameter The diameter of a circular capillary equivalent to the largest aperture of the microporous membrane. Note. Rewrite GB/T 20103-2006, definition 5.1.5. ......
