Apakah Perbezaan Antara Penyahgaraman Terma dan Penyahgaraman 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 penyejuk DC menghilangkan sebahagian daripada haba dan daun

(4) Jumlah air yang dihasilkan dalam sistem berkait rapat dengan jumlah stim

(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 adalah besar, dan jumlah operasi dan penyelenggaraan adalah kecil.

Penyahgaraman 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 berskala kecil, fleksibel dalam operasi, dan besar dalam operasi dan penyelenggaraan

Secara keseluruhannya, kaedah terma mempunyai jumlah pengambilan air yang banyak, suhu tinggi air yang dihasilkan, dan memerlukan air laut untuk penyejukan, kualiti air produk adalah baik, dan prarawatan adalah mudah.

 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.
