Desalinasi

Desalinasi atau pengawagaraman adalah proses yang menghilangkan kadar garam berlebih dalam air untuk mendapatkan air yang dapat dikonsumsi binatang, tanaman dan manusia. Sering kali proses ini juga menghasilkan garam dapur sebagai hasil sampingan.

Dua metode yang paling banyak digunakan adalah osmosis terbalik (47,2%) dan distilasi kilat multi-tahap (36,5%).

Pada kehidupan modern seperti saat ini, proses desalinasi difokuskan pada pengembangan cara yang efektif untuk menyediakan air bersih untuk digunakan di wilayah yang memiliki keterbatasan air. Desalinasi pada skala besar biasanya menggunakan sejumlah besar energi dan infrastruktur spesialis, sehingga sangat mahal dibandingkan dengan penggunaan air tawar dari sungai atau air tanah.
