deionized vs distilled water?

[iandh]

Okay, I'll do that.
But the question remains, wich water is better? Pharmacys or the gas stations?

Just guessing I would say the pharmacy water.

Okay, I will try to find out more about it.
Coming with more info later today.

Yes, but if you get a leak then in my understanding lower us would be better, right?
So paying a couple bucks extra för the pharmacys water could save components worth hundreds of $.
Or am i thinking wrong? Perhaps it does'nt even matter if its 0,1us or 10us?

Once the water - distilled/de-ionized/pharmacy/battery/etc. hits your loop, it's going to no longer be "pure," as it's going to absorb ions from the metals in the loop. The potential for more expensive water to save you from damage if you get a leak is (in my opinion) nil.

Okay, thanks for explaining!
But then why do the water quality even matter? Why is 0,1us better than 500us?

Lower value, cleaner water. Once it gets below certain point, it really does not matter, though.

Because when the water robs ions from your loop, you know what materials are contaminating it. If you don't start with pure, who knows what is in it. The last thing you want is calcium, salts, or organisms in your loop.

At Kleenco we produce only the purest Distilled water & Demineralised water.
The stringent process we use to produce distilled water and demineralised water that has been tested and Certified by NATA Accredited Laboratories.
Kleenco deliver Distilled water Sydney and Australia wide.

You can rest assured that our Distilled water is suitable for use in any industry or application.
We test the conductivity of our distilled, demineralised water on a daily basis and guarantee a reading of 2.8 mS/cm or below.
To view the conductivity result of our distilled and demineralised water, click here to see the analysis.

I like Pretty reasonably priced too...
I can't tell from their site whether they're also doing DI, sounds like they're only doing distilled.
But it's down to a good level, and at least you can have more certainty over what you're getting.
Still tempted to buy a TDS meter though, just for fun

i dont see a point using deionized water since it will take the ions from the copper and/or silver if you have some in there. If it leaks, it will still damage your components. I just run distilled all the way with a silver coil. No additives of any kind. Dont use tap though! I did that my first time I filled it and got white crusting in the res and white gunk on the tubes from the minerals and chemicals in there.

[rge]

Both distilled and deionized are deficient in ions and both are going to take ions from the copper and/or silver. Quickly at first, then as water gains ions over few weeks, neither will be deionized any more, and in time leaching of ions slows to point of no faster than mineral water. Your not supposed to run continually fresh either distilled or deionized water through copper pipes as after many years and millions of gallons it can erode the copper. However, there is nothing wrong with circulating forever the same distilled or deionized water through, since after a few weeks, neither will be deionized anymore, and neither will be any more harmful than natural mineral water, ie you just turned your deionized water into mineral water.

If you want to see how quickly distilled or deionized gains ions and hence is no longer deionized, read here.

[pogiman]

I had a ChemE friend going for his doctors who runs a lab that produces pure deionized water with very expensive machines. At first, I wanted to use this water in my loop but then he told me that I should not use this water in anything that contains metals since it will harm them. Thats when I went with distilled. My main goal was to avoid buildup of unwanted organisms and precipitate of any kind. It has been almost a year now and all I have is a silver coil and distilled water. Besides, even if you can buy deionized water, it will be much more expensive than distilled and in the end, they both end up no better than tap water.

[jalyst]

That's odd,
Most of what I've read suggests that DI is generally a cheaper process than distillation.

But I totally get how metallic ions will eventually equalise to the point that there's little difference.
Other than distilled having no colloids or micro-biotic material (if done well)...

Night.

[Sadasius]

@Mabyboi Just come to my place with a big jug. I have a high end R/O system that makes it better then distilled. I won't charge you a dime! Other then that just go to your local Shoppers Drug Mart bro. They have distilled there dirt cheap in 4 litre containers. Cost something like $2.75 or something like that.

Could be, but the machines used to de-ionize the water is about $30k each. The filter alone is $5k. Maybe the prices are not the same since I cam comparing this against lab grade stuff. I figured whoever is selling this stuff better get some money back.

[Biffa]

Just get whatever is cheaper or available in your global location. In europe its easy and cheap to get deionised, in the US its the opposite and distilled is more readily available.

[jalyst]

Confused.....
How can you make that claim when there's greatly varying grades of distilled?
Same for R/O too...

Are you saying better than run-of-the-mill "supermarket grade" distilled?
If so what measurements are we talking?

Cheers

Yeah there's no doubt the high-end gear is pricey for both processes.
From what I've read, DI is not quite as Labor intensive/energy consuming.
Both can still get extremely technical/pricey set-ups/gear...

No need to be confused. I have a condition in which I am very sensitive to Fluoride. Living in a city in which they fluoridate the water can make it challenging for a person like me to stay alive. Natural calcium fluoride is okay but the stuff they use in municipal waters is extremely toxic and I am sensitive to it. The distillation process does not get rid of most chemicals as it evaporates with it. However it is great for cleaning out minerals as that is left behind. My R/O system not only takes out minerals but chemicals, hormones and even radioactive material such as radium and tritium. This is why I made the claim I did. Read up on each process and see which one's are best for making the purest of water. Now what happens in the end is funny too because the water then tries to reestablish it's minerals to maintain it's Ph balance. It's a good study. I read up on it because well...my health was involved.

[Conumdrum]

RO is enuff, if the filters are new.

We get stuck on numbers, once the numbers are low enuff, it's fine. Any other discussion is a waste of time.
Just a quick link to some numbers I did for an upgrade.

Using very pure water you are going to have a negligible amount less of residual but a LOT of aggressivity more toward metals.
Distilled + silver coil is NOT enough,anticorrosion is needed,cause in watercooling loops there is not only corrosion due to mixing metals but also oxydation due to the aggressivity of the pure water.
And once you use anticorrosion you can also throw your silver coil since anticorrosion are also anti algae/fungi. At that point i'd prefer deionized over dstilled since the only up of distilled is that it contains less microorganisms but the down is that steam purified water contains much more easily impurities (like chemicals) that are easily eliminated with deionized.
DOn't want to seem arrogant but in watercooling loops it is so popoular this assumption that distilled + silver coil is enough....but as someone else also stated before, pure water (like one that is around the conductivity values that you were talkingabout) is going to be exceptionally aggressive toward metals.

jalyst, why are you making liquid cooling look harder than rocket science?

I'm sorry, on what basis do you make that assertion?
Yikes 4am! good-night.

Lets start with looking for the water with the lowest TDS levels. Your country's government sets minimum standards for all forms of water that must be met in order for it to be sold with that particular labeling on it. These standards, while not exactly the same in every country, are relatively close in most of them. Distilled is going to be the most recommended with DI not far behind, looking for a producer of either that can do it better than everyone else in your area is not really necessary as it won't make much difference after a while in the loop. I applaud your willingness to go the extra mile in your research (it's rare to see these days) but, your over thinking things a bit.

[josh1980]

Here's the difference:

Distilled water: Water is boiled and then recondensed. The recondensed water is free of any impurities that are NOT transferrable in steam. Many chemicals will transfer through steam, but the vast majority of what most people care about will be removed by boiling water. If you had ammonia and water mixed together you could not separate the ammonia from the water with this process. Think about all the "stuff" that would collect in the bottom of a pot of water on your stove if you boiled off all of the water. All that stuff is removed and you are left with the "cleaner" distilled water.

Deionized water: The water is passed through an ion exchanger that removes hydroxide and hydronium molecules. The quantity of hydroxide and hydronium determines your pH. Often deionized water is also distilled, but there is no requirement. The reason is that distilling and deionizing the water is often cheaper than straight deionization. Basically, Deionized water should have a very close neutral pH. Ammonia would be filtered out by the deionization process. However, any dissolved solids in your water might not be filtered out by deionization. Keep in mind that a neutral pH may not be the best pH to minimize corrosion. Only metallurgical engineers could really comment on the best pH for a given material. I am sure that the information we IT geeks would want to minimize corrosion is not available to us in any form.

Purified water: Purified water is water that has gone through some form of physical filters to remove impurities. This could be reverse osmosis or other form.

Each type of water has a different intended goal. Distilled and purified water tries to remove dissolved solids(but with 2 different processes) and deionized water tries to establish a neutral pH.

So which is better for your system? Honestly, I'd go with whatever I can get the easiest/cheapest between deionized water and distilled. Purified water doesn't really have any requirement for maximum amount of solids that can still be dissolved in solution.
