Diffrence between purified and distilled water
- Thread starter fiqa
- Start date
Why do people keep on insisting that deionised water is acceptable without clear mention of the requirement to include corrosion inhibitor. The fact that the water is deionised will force corrosion. But iit is still worthwhile mentioning that the use of deionised water will prevent/reduce any microbial growth.
Distilled water should be used with growth inhibitors, and in an ideal world there should still be corrosion inhibitors just as a precaution.
Best bet is to use pre-mixed coolant solutions as these come with the right grade of water and associated inhibitors.

The search works pretty well you know
Pretty much the same thing...

Distilled and Deionized water can all be totally different. Purified water is a broad term to use and can mean RO-Water, Chlorine water ect ect and normally is reference to drinking water.
Distilled water removes and kills allot of bacteria and other nasties in one go via steam / Pressure treatment. This is normal better than Deionized water.
Deionized water is simple filtered water then it is pushed though a bed of DI resin to "polish" the particles off. Its is not the purest of water and still has a lot of trace elements left over.
RO Water is better than DI and again it depends on how its made as there are many different types of filers. RO water is worked on a TDS% of what goes into the system and what comes out. E.g you could just have a simple RO system that produces 25 TDS water with only 3 filters or you could have a system like one of ours that has over 13 filters that remove heavy metals and many other types of filers, then goes though RO membranes then DI resin bed and finally a UV filers to produce 0 TDS water at source.
RO system can produce many different levels of water depending on what and how much is removed. There is a small issue though as the more you remove the more than can be sucked back in. So you have to balance out what you remove and even some times put back in certain chemicals or metals to balance it back out.
you can read up more on Wikis here -> http://en.wikipedia.org/wiki/Purified_water
Storing water as well can impact on what you are getting. E.g storing water in leaching plastic bottles above 22c will see it increase its TDS rapidly. Water from car shops (local dealers not halfords) is normally better than Super store or Halfords water. Halfords water is better than super market water. Super market water is a pure gamble, we have seen it from 5us up to 30us (40 tds)

My local Tesco sells carplan di water which is the same brand sold in most autofactors. 
Thanks mayhem for the detailed overview. For now I have one local pharmacy
Which has purified water in stock. So I will get that for now and after that I will go for mayhem liquids. Its just I can't wait for my first water cooling build and don't want to wait for another delivery. Anybody knows that where I can get ptnuke in Ireland or is there any other liquids I can use
