Cad É An Difríocht Idir Díshalannú Teirmeach Agus Díshalannú membrane?

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) Tógann uisce fuaraithe DC cuid den teas agus fágann sé

(4) Tá dlúthbhaint ag an méid uisce a tháirgtear sa chóras leis an méid gaile

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

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

(7) Tá scála an mheaisín aonair mór, agus tá an méid oibríochta agus cothabhála beag.

Díshalannú membrane

 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) Tá an trealamh beag i scála, solúbtha i bhfeidhm, agus mór i bhfeidhmiú agus cothabháil

Ar an iomlán, tá iontógáil uisce mór ag an modh teirmeach, teocht ard an uisce a tháirgtear, agus éilíonn sé uisce farraige le haghaidh fuaraithe, tá cáilíocht an uisce táirge go maith, agus tá an réamhchóireáil simplí.

 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.
