Desalinasi

Desalination atau desalinization adalah proses yang menghilangkan kadar garam berlebih dalam air untuk mendapatkan air yang dapat dikonsumsi binatang, tanaman dan manusia. Seringkali proses ini juga menghasilkan garam dapur sebagai hasil sampingan.

Dua metode yang paling banyak digunakan adalah Reverse Osmosis (47,2%) dan Multi Stage Flash (36,5%).

Schematic of a multi-stage flash desalinator
A - Steam in
B - Seawater in
C - Potable water out
D - Waste out
E - Steam out
F - Heat exchange
G - Condensation collection
H - Brine heater
