열 담수화와 멤브레인 담수화의 차이점은 무엇입니까?

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) DC 냉각수가 열의 일부를 빼앗아 나간다.

(4) 시스템에서 생성되는 물의 양은 증기의 양과 밀접한 관련이 있습니다.

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

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

(7) 단일 기계의 규모가 크고 작동 및 유지 보수량이 적습니다.

멤브레인 담수화

 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) 장비 규모가 작고 운영이 유연하며 운영 및 유지 보수가 큽니다.

대체로 열법은 취수량이 많고 생산수의 온도가 높으며 냉각을 위해 해수가 필요하며 생산수의 수질이 양호하고 전처리가 간단하다.

 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.
