An affordable water distillation system based on solar power.


Solar distillation for zero liquid discharge recovers pure water plus dry salts and avoids the generation of contaminating brine.

A system for water re-use, including getting rid of brine, water desalination's unsustainable waster, achieving the closed water loop. SunAqua looks like a huge tent, its configuration allows it to gather the Sun's heat with a high efficiency and to use it to evaporate water. In the case of water desalination, the dominating current alternatives capable of desalinating water only recover a fraction of the water and dump the rest, which is harmful, back to the sea. SunAqua, on the contrary, evaporates 100% of the water, recovering the solutes (ex. commercial salt) following a full waste-to-money philosophy. Whether sea-water, brine or contaminated waters, SunAqua achieves a full separation of water and its solutes, leading to the generation of resources (commercial salt, fertilisers, ...) or an easy and cheap management of the waste in its solid state.
