Re: Water distillation under vacuum

All valuable points. I was working on the assumption that a partial vacuum would make it easier for the water to vapourise. But I think a side effect is that it would be less likely to condense. The system I was thinking of would use rubber bungs which would easily blow off if the steam pressure was...

Water distillation under vacuum

Thoughts on this idea? One method of making water safe to drink is by distillation. This both used heat which kills biological contaminants, and evaporation/condensation which separates the water from non-biological contaminants. I have an idea to do this under a lower pressure system, so that the w...

I'm 43 and qualified as a nurse about 20 years ago, so feel I have a very valuable skill in the health-prepping area. I look forward to contributing to this forum and...
