Passive Desalination with photovoltaic pumping

[kandrathe]

How do you prevent the slat from crystalizing out everywhere? I understand these systems work by just evaporating a little bit of water from sea water so that what they send back is just slightly more saline, but in every angle or with every splash you get salt forming in these devices. That can be very difficult to clean up.

I guess I would explore a marine tolerant concrete, and use sealer coating like Siloxa-Tek 8510. I would expect part of the engineering would be to find a design needing minimal manual maintenance.

Thanks to ancient Romans... saltwater resistant concrete
