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
21세기 물산업은 20세기의 석유산업의 블랙골드 시대에 대비되는 블루골드시대라고 불리고 있다. 미국 경제전문지<포춘>은 “물이 국가의 부를 결정하는 귀중한 생필품이 될 가능성이 크다.”고 보도했고, 애덤스미스의 국부론에서는 물의가치와 가격을 다이아몬드와 비교하여 설명하기도 하였다. 현
2000 B.C - The first recorded (The Susruta Samhita, Sanskrit writing) water purification began with the Egyptians. It is said that impure water should be boiled over a fire, heated in the sun, have a hot iron dipped into it or purified by filtration through sand and course gravel.
A major step in the development of desalination technologies came in the 1940s during World War II when various m

Permeability & Energy consumption
If permeability is a high value, membrane area is decreasing.
It can decrease the costs of the desalination.
