Description
Membrane distillation PTFE membrane has many advantages:
(1) The membrane distillation process is almost 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 distillate is very pure and is expectedBecome an effective method for large-scale, low-cost preparation of ultrapure water;
(3) Membrane distillation modules are easy to design into the form of latent heat recovery, and have the flexibility to form a large-scale production system with high-efficiency small membrane modules;
(4) In thisDuring the process, there is no need to heat the solution to the boiling point. As long as the two sides of the membrane maintain a proper temperature difference, the process can be carried out. It is possible to use cheap energy such as solar energy, geothermal heat, hot springs, waste heat from factories, and warm industrial wastewater.
