Bagan sederhana(01)

Keterangan bagan(01)Kisaran pH adjustment 6 – 11 .Tekanan (high pressure pump) = 900 psi.Setelah masuk feed dihasilkan air normal

(kadar garam = 500 mg/L) dan air garam pekat ‘brine’ (kadar garam = 35000 mg/L)

Gambaran lengkap bagan

Tahapan secara industriDisaring dengan ukuran ¼ inchi, dari pasir

dll. melewati particle settlement, sand filter, dan

melewati diatomaceous Earth filters.Di Reverse Osmosiskan kemudian

di’Thermolityc’ kan dengan campuran gas CO2-NH3 sambil dipanaskan pada suhu 590 C.

Thermolytic Draw Solution:NH3/CO2
