Is Solar water desalination Operates on the daylight only? Can it operates after sunset? Can it produce pure water on the midnight for example?
Thanks S. Feroz for your contribution. But how phase change materials operate?
I would like to propose for power storage electric batteries of flow batteries.
The answer depends on the wanted quantity of freshwater. It is simply possible to increase the capacity of the desalinization system and store the freshwater water instead of power for the night.
Thanks S. Feroz but i did not mean batteries I ask about how to continue desalination at night?
Thanks S. Feroz
Phase Change Materials PCM is also a technique to continue desalination
Yes if we use energy storage system. As we know that solar radiation only exists at day time. So, the excessive energy should be stored for desalination process at night. The energy storage system depends on whay desalination process we use. Generally, desalination can be divided intro electrial and thermal based desalination system.
Reverse Osmosis is one of the electrical based desalination process. If we use this process, so we need battery system for desalination at night time.
On the other hand, thermal based desalination such as simple distiller, MED, MSF, and MD needs thermal energy storage. This kind of energy storage can be sensible heat storage such as heat is stored in water or latent heat where phase change is involved when storing and releasing the energy (PCM).
Thank You Tri Ayodha Ajiwiguna for your answer. PCM is the suitable energy storage material in this case. Thanks
PCM or under ground heat energy storage systems may be designed to allow desalination at night. Low night temperature offer higher efficiency than day time.
