Well, if we were to go with waste water that can't be used for anything, there would need to be a disposal method. Besides, we were talking about a non-sulfide based process, so it would be pure water out if anything.loganb wrote:The depleted water should not be recyclable, I was going to suggest "mineral water" but then realized that's an Angel's thing. There should be a concept of a wastewater that isn't useful for anything.
To be more precise, the steps would be:
- Sulfide process that consumes water and small amounts of Hydrogen Sulfide, outputs depleted water and Enriched Water (HDO)
- Fractional Distilation where the inputs are heat and Enriched Water, and the output is Deuterated Water and depleted water
- Electrolysis where the hydrogen electrolytes preferentially, leaving D2O and Hydrogen Gas
Besides, from what I understand about the sulfide process, it actually creates D2O (by shuffling around the Deuterium into a single heavy water molecule) rather than just separating the HDO from the H2O
