Process of Seawater desalination

`mimetic diagram`

1. Water intake

 

2. Pretreatment : remove debris and impurities

(fine sand, solids, microorganisms for life of

membrane. & inject Antiscalant, Biocide etc)

3. Reverse Osmosis : extract fresh water from seawater by membrane.

Speaker : Ahn joon sung

 

Reverse Osmosis

Osmosis

Low concentration

High concentration

Semipermeable membrane

Driving force is chemical potential by difference of solute concentration.

H

H is osmotic pressure.

Speaker : Ahn joon sung

Osmotic Pressure π = CRT

π : Osmotic pressure

C : Molar concentration of solution

R : Gas constant

T : Temperature

 

Reverse Osmosis

Reverse Osmosis

High concentration

Low concentration

Semipermeable membrane

pressure

When put on high-pressure than osmotic pressure,

 

The water in high-concentration side is moves to low-concentration side.

 

Osmotic pressure : 20 bar / Reverse osmotic pressure : 60 ~ 70 bar.
