All you have to do is transfer the salt from time to time from the lower tank and voila: there is salt at the bottom and fresh water at the top.
Well I have already thought a little bit about such a system and it seems to me that it is not so simple ... because to condense you need a "cold" surface ... but on your diagram it is the condensation surface is a priori the hottest ...
It would therefore be necessary to bury (or put under water in the case of a floating system) the "condenser" part ... but in this case a "circulator" would be necessary (1 pc fan 12V connected to a small PV plate for example?)
So then play on the day / night cycle but in this case the production may be quite low ...
I am wrong?
In any case I do not understand that such systems do not exist ... worse, it seems that no prototype study has ever been developed ... well I never came across it personally ...
Of course, I simplified the diagram. For this to work, it would suffice to give the device a still shape (for the part containing sea water. The vapors would be conveyed by a tube to a buried tank (for example) so that its walls are cold.
