deionized water

[jbslow]

Hi guys I have got my bong all hooked up and modded a 2 gallon reservoir and I found out its going cost at atleast .79c a gallon for distilled water from the store. I am not totally sure how much but I think by evaprotive cooler will go through a good 2 gallons every day with my house at 79c this could get a little expensive.

At my work we have a water setup and the little tag says deionized water we use this to fill up golf cart batteries. I want to know if this is the same as distilled water if not whats the difference?

[phiber]

yo....i would think that you get it in mass.....like call Poland Spring and tell them you want lots of distilled water...itll definatly be cheaper...

[ButcherUK]

Deionised is similar to distilled - normally it's distilled which has been treated to remove ions from it.

[MiseryQ]

Uh... Is tap water bad?!? I hope not 'cause that's what I have in mine... I only use about 1/2 gallon day... That was before my new 4" fan though...

[Strangelove]

OK here we go:
The difference between deionised and distilled water.

Distilled water has been boiled and the vapour is collected (condensed) the ions and other contaminations does not go into vapour form so it stays in solution.
Deionised water runs through a column, in this column all ions are exchanged, this means that positive ions are replaced with H+ ions and negative ions are replaced with OH- ions which all together makes H2O (water).

To get perfectly clean water and I mean pure H2O run distilled water through a deionising column. Hey I’m a biochemist and I use very VERY pure water for experiments ;)

Please forgive any spelling errors, I'm very drunk right now :beer:

Have you ever heard of corrosion????

[MiseryQ]

Oh...

I only have one metal part in my system, and that's inodized aluminum...

[jbslow]

Well guys the deionizing column may be hooked up to the tap I'm not really sure there is a couple of tanks their...if it is infact tap water that has been deionized should I use it or will it still have all those corrosive properties?

[neo86]

Not exactly a good idea for a bong cooler, but in a normal watercooling system (radiator) couldn't you just use watter wetter to deionize the tap water?

Really...... no pump????

About iodised aluminium, that will just give you a bit more time..... Corrosion is a question of redox reactions, this means that multiple (different) ions are Baaaadd (question of ion charges and electron affinity) you might help it out by adding anticorrosive like antifreeze. To be perfectly honest I'm planning to set up a H2O system with a copper block and an aluminium Rad (but with at least distilled water) corrosion will not be a problem for several years ;), the major problem with using tap water is CaOH and other salts that might come out of solution when evaporation occurs.

Soo the only conclusion is that I'm getting even more drunk and corrosion will not be a problem for quite a while all though I would recommend using distilled or deionised water due to sediment problems.

Please explain how??? (sediments???)

[flounder43]

I believe that water wetter reduces surface tension in the water.

In theory if the water is completely deionised you will only have to worry about ions from your block and other metal parts in your system, however I would recommend using some type of anticorrosive!!! :D

[Greedy Guido]

I use plain tap water in my cooling tower. I add a little green stuff (better known as corrosion inhibitor) and my system stays nice and clean.

The down side is that I have to vent it outside to avoid sucking in green stuff vapours.

As the green stuff boiling point is much higher then water I only add more when I clean my system ever 4 to 6 months.

"better known as corrosion inhibitor"

I should have said "car radiator corrosion inhibitor" but though everyone would known what I was talking about. Sorry for the confusion.

Confusion??? Who’s confused??? I just wanted you to clarify your writing, green stuff is not exactly very specific;)

Its time to put this one to rest. De-ionisation is a simple chemical ion replacement system devised by Dowe Chemicals many years ago and the mechanism was explained earlier in the thread. Cations exchanged for H+ and anions exchanged for OH-. The process is not 100% and the best tolerance is removal of most ions and the water has a residual content of about 1ppm (parts per milllion) of ions left. Ion exchange has its faults because it is a resin and is known to produce organic contamination and is a good breeding ground for bacteria and algae. The product is ideal for producing low cost purified water that contains low levels of contaminants that might be harmful in terms of corrossion and/or deposition but is not suitable for production of pharmaceutical grade injectable fluids because of organic contamination.
The production of distilled water is extremely expensive. A standard small distallation plant contains 2 2KW heater units and produces distilled water at the rate of 2L/hour. It removes all impurities (including bacteria) and is the only source for pharmaceutical grade water for manufacture of injectables.
To summarise - for the puproses of water cooling de-ionised water is fine - unless you are worried about your computer picking up some kind of deadly salmonella infection. Using distilled water is an absolute waste of money.
How do I know all this - I have a B.Pharmacy

Antifreeze. Comes in two colors, red/orange and green, never quite found out what the difference between the colors is, just that some cars require green and others red/orange.

~Vash~

[MiseryQ]

There's also an antifreeze called Sierra that's supposed to contain no harmful chemicals... I once came acroos a guy that claimed to be extremely allergic to even the smell of regular antifreeze... I did a major flush of his system and installed this stuff... Never heard about it again, I assume He has happy... Might be worth looking into... I don't remember wahtif any odor it had...

--I have a mag pump, while I have'nt opened it, looking down the intake the impellar looks plastic and the box claims the shaft is ceramic... Hence the "one metal" comment...

[UserName]

The pink/red/orange stuff is used in new cars as it's enviromentaly friendly

Don't use de anything in your bong. There is no point. It's a bong and your gonna blow air over it. It will get dirty and ionized.

Use tap water and and some chemical to kill stuff and stop corosion. Antifreeze is cheap and you only need a bit.

If you got really hard water boil it first.

[CrystalMethod]

Another reason to use distilled water is to avoid the deposits of minerals that will eventually gum up your cooling system. Anti-freeze is in no way "environmentally friendly", I don't care what the package says. Proplyne-Glycol-antifreeze is what you're reffering to, and even though, it less hazardous than regular Ethylene-Glycol-antifreeze, it's still very toxic.

Not smart you will only increase the salt concentration if you boil it!!! The sediments you see when you boiled water, appear because you have reached saturation of the water, which is the opposite of what you want. In fact if you heat it and cool it down slowly you might even get lucky and have an oversaturated solution, which means that even more sediments will form when you pour it into your system.

[UserName]

you are correct.
However, most of the white/yellow sediment is calcium carbonate, and thats the junk that plugs everything up. this falls out of solution when you boil water. not a pure or complete fix but it greatly reduces this contaminite, and gets rid of growing things as well.

most who find tap water works ok but get lots of "white gunk" in their bongs will find this reduces it considerably.

[ButcherUK]

Propylene gylcol causes problems with the plastics commonly used in water cooling. Use it at your own risk! (And that's a big risk). Ethylene glycol or water wetter are all I would recommend.

[UserName]

I did not know that Butcher

How and what are effected?

Might want to let joe know cause i could see someone going to the parts store and getting the pink stuff cause it's enviromentaly frendly, or more correctly more enviromently frendly.

[dabhpr]

Alright, so the question is: Where do you buy deionized water?

[UserName]

most grocery stores.

Ther real question is why would you use it?

[MiseryQ]

I just checked Sierra (http://www.sierraantifreeze.com/benefit.html) claims to be "less toxic"...

[res0r9lm]

butcheruk might be refering to the red antifreeze "dexcool" it eats plastic up. there is no reason to use antifreeze unless water is going below freezing. For maximum heat transfer use water wetter.It also fights corrosion while lowering tempature 10c compared to 50% antifreeze/50% water

[UserName]

so it will kill you slower?:eh?:

[Tiger]

Yes I am very curious about why people insist on using purified water. I have a very strong chemistry background and my experience and practical knowledge tell me its a total waste of time. The first circuit around a cooling system adds enough electrolytes to kill a system if it leaked anyway. Condensate, although pure, dripping on a circuit board picks up enough electrolytes in a few seconds to cause a short very quickly - this I have personally experienced.
I think that the normal domestic water purifiers that remove the common things like lime are fine. They are common in the UK. By the way, boiling water achieves nothing except concentrate the electrolytes and kill any organisms in the water.
The cheapest purified water is rain or snow - its free.

I understood calcum carbonate falls out of water if it's boiled

less toxic?? you gotta be kidding. dead is dead. all of it will make you croak. the problem is antifreeze tastes so good.

had a leak in my system didn't kill it was using straight tap water.
corroded agp slot although

[muddocktor]

If you want to use distilled water, you can get home distillers at Sears for about a hundred bucks and they will make 2 to 3 gals/day. Also, in the town I live near, they have couple of water stations that run tap water though an 8 stage filtration process which gets the water to almost the same purity as distilled water. If you are really serious about making lots of distilled water, there are several companies that make partial vacuum/waste heat extractors that do an admirable job, but are mega-expensive.

I got an idea, we'll test both. I need some volonteers. :D

[UserName]

BAD BAD BAD.

Funny but bad

that can't be your pic as you are wearing a t-shirt and montreal is way too cold for that kind of behavior

[MiseryQ]

Yeah, less toxic, I think I know why I never heard anything from that guy...

And as a mechanic I can tell'ya that stuff does taste pretty good...

Don't ask...

Gylcol is a sugar. ever want to get rid of a small animal leave a bowl of it out.
You know, that yappy dog or whatever

Tiger: A can of purified water is cheaper than a purifier. ;)
As for rain you should know that it's not pure - it picks up all manner of crap from the air, such as sulphur dioxide and such. I'd rather not have mild acid in my system thanks.

A can may be cheaper but a purifier can produce many cans so its not cheaper.
As to contamination in the atmosphere - that depends on largely where you live. If you live in area where there is still a lot of fossil fuel being burnt then sulphur dioxide can be a problem. This is not a common problem in most developed countries with current polution regulations in force. The amount of contamination is minimal and I would be keen for you to supply proof to the contrary.

[ButcherUK]

Well as I don't have a water testing lab here to check my water... still I live fairly near a large fossil fuel power station (about 20-30 miles), so my rain water probably isn;t that great. Still it's your water setup that's at risk ;) As a lot of people here live in america, which is the most polluting country in the world it wouldn't surprise me if their rain wasn't that great either.
For a bong setup a water purifier works well but a lot of people don't run a bong so just buying some purified water makes sense. My system uses 2l of water, that's £50 (or whatever) for a purifier or £1 for some water :p

[Tiger]

I looked for some stats on the UK pollution levels and the worst place in the country was 27ppb (parts per billion) of sulphur dioxide which is on the low side and most places were 2. This concentration will have absolutely no effect on the pH.
We are probably not talking the same water purifiers. The domestic form, available at most supermarkets, retails for £10 and produces several hundred liters of water before requiring a new element.
