X'inhi d-differenza bejn id-desalinizzazzjoni termali u d-desalinizzazzjoni tal-membrana?

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) L-ilma li jkessaħ DC jieħu parti mis-sħana u l-weraq

(4) L-ammont ta 'ilma prodott fis-sistema huwa relatat mill-qrib mal-ammont ta' fwar

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

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

(7) L-iskala tal-magna waħda hija kbira, u l-ammont ta 'tħaddim u manutenzjoni huwa żgħir.

Desalinizzazzjoni tal-membrana

 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) It-tagħmir huwa żgħir fl-iskala, flessibbli fl-operat, u kbir fl-operat u l-manutenzjoni

Kollox ma 'kollox, il-metodu termali għandu ammont kbir ta' teħid ta 'ilma, temperatura għolja tal-ilma prodott, u jeħtieġ ilma baħar għat-tkessiħ, il-kwalità tal-ilma tal-prodott hija tajba, u t-trattament minn qabel huwa sempliċi.

 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.
