Yup. Distilled only or risk brain eating critters.

"Distilled Water", the typical water you buy as distilled is not heat distilled and not sterile. They use reverse osmosis and or ion exchange resins to remove all the minerals from the water. It's fine for irons, but should not be considered sterile.

RO may be energy efficient (I honestly don't know if it is or is not).... but they are a huge waste of fresh water. The amount of water waste used in flushing the RO membranes is huge. Maybe there's a lot of waste in distillation as well? I don't know.... I just remember being shocked at how much water was sent to drain (in California no less!) to create RO purified water.

I'm not sure home RO systems and the Navy's RO desalinization systems are the same.

They're turning seawater into safe drinking water.

That's probably a much better application, as any waste water from the process is just flushed back into the ocean where it started.
I wasn't talking home-use. I worked with a couple water purification systems for pharma companies... those are using already "clean" drinking water and purifying them further down to sterile. That's a huge waste, as the waste water is actually clean drinking water, that's just being flushed down into the drain.

I'm surprised they do not repurpose it.

It's a pharma company. Technically the water is "waste"... there's no way it could be used in any manufacturing since there's no certification on the composition... it would have to be put in some sort of holding vat if it were to be used for employee drinking water or flushing, and that would require all sorts of work to prove you're keeping that clean.

So they just flush it.

FYI, RO can be used for purifying tap water, or for desalinating salt water. I believe it is the same principle, and likely almost identical equipment. There may be small differences I'm not aware of, but probably only for efficiency and because of the low cost (free) of supply water for desalinization.

You would think they could have used it for fire suppression or something similar..... but I get the certification obstetrical.
