Default Cheap 99.9999999999% pure distilled/de-ionized water in Australia

Just some info for my compatriots. i'm not sure if this is really the right place or whether construction techniques may have suited better. I was recently searching for a reasonably priced, easily available source of distilled water for rinsing projects after soldering/reflowing and after the brush with alcohol to get rid of flux and generally make it shiny/clean.

after finding some of the local prices for small amounts at electronics supplies stores quite ridiculous, or only for huge amounts, I did a bit of googling. I came across a company called refresh that uses a patented evaporation process (I guess the machinery is patented) to get what is essentially 100% pure water (it is essentially, but they cannot guarantee 100%, so have to say 99.999..%)

they do not stop at industrial grade, but take it to food grade, so no chemical residue like some other distilled water I saw, nothing at all, just water. the best bit is you can buy it at Woolworths under the name Moores ultrapure, or refresh, so I only had to pop up the road. ~$4 for 5lt and I can use it for drinking too. they deliver for the larger amounts in 20lt (think you need to get 2 x 20lt for free delivery)

So anyway I thought it was a cool find and may be of interest to someone on here, since its useful for drinking as well as any production, or scientific uses and handy; since Woolies are everywhere.

Drinking distilled water is hazardous.

That's what I was wondering. How much of the packaging leaches into the water? Is the container clean when filled, etc.

They're claiming 100ppt, if this is being quoted accurately. That's... interesting.

1ppm is pretty darn good and easily good enough for the high purity stuff that we do at work. That has to be carefully packaged in uncoated glass, with a special closure, otherwise leachates from that package will increase impurities to 20 times that.

not this type it isnt, it really would be better if you read the post before replying... drinking water that only qualifies as distilled water ie industrial, non food grade water is hazardous as it isnt purified/processed with food regulations in mind and may contain trace of industrial processes, particulates etc. but that is not what we are talking about here and I thought I made that pretty clear. are you saying that drinking rain is hazardous?

I gather thats why they cannot claim 100% that the containers and atmosphere, or delivery cannot be guaranteed to be 100% free of impurities that are beyond their control. its packaged in numbers of ways, the 5lt bottle I got is in a plastic bottle, but labelled BPA free ie No Bisphenol A in packaging.

Also no chemicals, no salt, no bacteria. its steam distilled. they also sell it in 20lt containers for work/office watercoolers, as well as by the tanker load among other methods to food producers, scientific and industrial etc. I got it in the drinking water isle at the largest supermarket chain in the country afaik, Woolworths/Safeway. they are the largest supplier of purified water in Australia, but its not spring water, not what is normally called distilled water; it is essentially pure water made by evaporating and condensing water and using processes, packaging and delivery that has qualified under the regulations, so it qualifies as all of the above. (by that I mean distilled, deionized, drinking water)

I added the extra 9's for effect

I guess the packaging will vary depending on the requirements of the consumer. what I got is sold as pure drinking water, so who knows exactly the purity in this package, which as you guys have rightly brought up is probably the dominant factor for purity of the end product you receive. I would guess that the 100PPT is the water before packaging and if you really need the highest purity there are other methods for packaging.

These guys are not one of these lifestyle water brand companies and the guy didnt hype me on anything, he put me onto the fact that Woolies had it because he doesnt deal with 5lt bottles, only 2 x 20lt and up.

I have no reason to disbelieve him. it says nothing of the exact purity on the label of the bottle here, its very simply packaged

$4 for 5lt is hardly elite for drinking water.
