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 kjølevann tar bort deler av varmen og går
(4) Mengden vann som produseres i systemet er nært knyttet til mengden damp
(5) Low salt content in hydration (510mg/L)
(6) The water quality requirements are low, and the pre-processing is simple
(7) Skalaen til enkeltmaskinen er stor, og drifts- og vedlikeholdsmengden er liten.
Membranavsalting
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) Utstyret er lite i skala, fleksibelt i drift og stort i drift og vedlikehold
Alt i alt har den termiske metoden et stort vanninntak, høy temperatur på det produserte vannet, og krever sjøvann for avkjøling, kvaliteten på produktvannet er god og forbehandlingen er enkel.
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.
