Apa Perbedaan Antara Desalinasi Termal Dan Desalinasi Membran?

Recently,we noticed sea water deslination in  new way:Thermal deslination.However,most project still use RO membrane desalination.What is the difference between thermal desalination and membrane desalination? 

Let's see it below :

Thermal desalination 

(1) The temperature of the produced water is high, and it needs to be cooled by sea water 

(2) The utilization rate of seawater is low (12 percent 20 percent ) 

(3) Air pendingin DC menghilangkan sebagian panas dan daun

(4) Jumlah air yang dihasilkan dalam sistem terkait erat dengan jumlah uap

(5) Low salt content in hydration (510mg/L) 

(6) The water quality requirements are low, and the pre-processing is simple 

(7) Skala mesin tunggal besar, dan jumlah operasi dan pemeliharaannya kecil.

Desalinasi membran

 1) The water production is greatly affected by the seawater temperature, the inlet water temperature decreases, and the water production decreases

 2) The effluent seawater has a higher salt content

 3) The total salt content (TDS) of the produced water is relatively high, about 350600mg/L 

4) Deboronation needs to be considered when producing water for drinking water 

5) High water quality requirements and complex pretreatment 

6) No need of steam, easy to start and stop 

7) Peralatan dalam skala kecil, fleksibel dalam pengoperasian, dan besar dalam pengoperasian dan pemeliharaan

Secara keseluruhan, metode termal memiliki sejumlah besar asupan air, suhu tinggi dari air yang dihasilkan, dan membutuhkan air laut untuk pendinginan, kualitas air produk yang baik, dan perlakuan awal yang sederhana.

 The pretreatment process of membrane technology is complex, the water production is greatly affected by temperature, the salt content of the produced water is high, the operation flexibility is large, and the operation and maintenance volume is large.
