Why we need high pressure for water purification? Is it possible to produce pure water at gravity pressure? Resources recovery at the end of the filtration process will reduce the cost of treatment. No contaminants dischrage to the environment. Ions separation processes conducted at gravity pressure will overcome energy and environmental barriers associated with conventional processes. Imagine that astronauts can recycle and reuse wastewater at very low energy. New polymeric materials are making this dream comes true.
Thanks for starting this discussion, @alialtaee! The Infinity Water Prize Design is concluded. I can move this discussion into our Global Visioneering, though? We’re currently debating subdomains there; i.e., areas of focus under the five domains (climate change, health, food, energy, and space) in which we’ll be designing prizes.
