demineralised/deionised/distilled?

Post by chris246810 » Sat Sep 12, 2015 12:17 pm

Is demineralised water the same thing as deionised and distilled water, and are they all suitable for keeping starsan without It going cloudy?

This is the water treatment we use at work which produces demin water. Something to do with ionic and cationic filters if I remember correctly.

Would the water this produces be suitable for keeping starsan clear?

They're all different methods. WIth my liitle knowledge (a dangerous thing?):

Distilled - heated, minerals left behind. Steam is then condensed to pure distilled water
Deionised - mineral ions are attracted to charged surfaces as water passed through, resulting water is almost pure
Demineralised - water is forced through a series of filters - reverse osmosis

all suitable for starsan

"cationic/ionic" suggest deionised to me

I don't know where you work, but the fact that you have that huge thing making water, says to me it will be fine. We had one like that at GSK. (galoxsmithkline)

As vacant says;
distillation, is condensed steam = very pure water
Deminlerlised,,, I'd say I'm not sure how they do it, but it takes out the minerials. How much of them I don't know.
Deinionised is where the filter mops up any remaining ions

If demineralised is RO and that RO is passed throu the deionising unit you have very good water.

Me I just use my RO water, (reverse osmosis)

Thanks for your help guys, ill fill a few bottles of that to bring home.

I work in powder coating, it's used as a final rinse after cleaning before being powder coated for the more high end customers who want a 100% perfect finish (Jag,Bentley etc)
