Koja je razlika između termičke desalinizacije i membranske desalinizacije?

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 rashladna voda oduzima dio topline i odlazi

(4) Količina vode proizvedene u sistemu usko je povezana sa količinom pare

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

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

(7) Veličina jedne mašine je velika, a količina rada i održavanja je mala.

Membranska desalinizacija

 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) Oprema je malog obima, fleksibilna u radu i velika u radu i održavanju

Sve u svemu, termalna metoda ima veliki unos vode, visoku temperaturu proizvedene vode i zahtijeva morsku vodu za hlađenje, kvalitet vode za proizvod je dobar, a predtretman je jednostavan.

 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.
