What Did Doosan Develop?
(MSF) Multi-Stage Flash Distillation: Seawater Is Heated And Evaporated,
After Which The Steam Is Condensed to Produce Desalinated Water.

Dialysis
What is dialysis?
Dialysis is a membrane process where solutes (MW~<100 Da) diffuse from one side of the membrane (feed side) to the other (dialysate or permeate side) according to their concentration gradient. First application in the 70’s.
General Principles
Separation between solutes is obtained as a result of differences in diffusion rates.
These are arising from differe
