Description

Membrane distillation (MD) is a membrane separation process that uses a hydrophobic microporous membrane with the vapor pressure difference on both sides of the membrane as the driving force for mass transfer. It can be used for water distilling and desalination to remove volatile substances from aqueous solutions. For example, when aqueous solutions of different temperatures are separated by a hydrophobic microporous membrane, due to the hydrophobicity of the membrane, the aqueous solutions on both sides cannot pass through the pores of the membrane and enter the other side, but due to the high water vapor pressure at the interface between the aqueous solution on the warm side and the membrane On the cold side, water vapor will enter the cold side from the warm side through the pores of the membrane and condense. This is very similar to the evaporation, mass transfer, and condensation processes in conventional distillation, so it is called the membrane distillation process.

Membrane distillation technology has many advantages:

(1) The membrane distillation process is carried out under normal pressure, the equipment is simple, the operation is convenient, and it is possible to realize it in areas with weak technical strength;

(2) The process can handle extremely high concentrations If the solute is easy to crystallize, the solution can be concentrated to a supersaturated state and the membrane distillation crystallization phenomenon occurs. It is the only membrane process that can directly separate the crystalline product from the solution;

(3) The membrane distillation module is easy to design In the form of latent heat recovery, it has the flexibility to form a large-scale production system with highly efficient small membrane modules;
