Using an RODI in a tattoo shop?

[RoTTen2TheCore]

A friend who owns a tattoo shop asked me if I could set up an rodi for him as he would need access to pure water.
Correct me if I'm wrong, but rodi units filter out bacteria. The water exiting the unit would then be technically medical grade and safe to use in the tattooing process of diluting ink and injecting it into the skin.
My concern is that since the water is pure, nothing would keep bacteria from growing in the water, say should a pipe be contaminated.
Would it be possible to rig a UV to a receptacle that would sterilize the water as it came out?

Any input/insight on any of this would be appreciated.

i'm sure his customers will love to know that his water purifier system was chosen based off of a discussion on an aquarium forum.

He asked me IF I could. Clearly if I'm asking, it's because I have concerns and since we are talking about components used in the reefing hobby, where else would be better to kick around ideas and opinions? Also, I'm sure you are an expert on all this since you offered no insight or opinion, but rather a smart @$$ assumption.

What is he using now for pure water?

 

[RoTTen2TheCore]

Bottled distilled water

 

[Fishmommy]

Distilled is the way to go since the heat of boiling kills bugs

There are RO/DI systems available that include UV like this one: http://purepro.net/ro105-uv.htm

 

[RoTTen2TheCore]

Thank you Timfish! I'll look into that!

Even with UV I'd be concerned about it not being truly sterile. I'm no expert but it would be my worry.

 

[Fishmommy]

I would think there are actual rules covering this.

 

[RoTTen2TheCore]

Not in Quebec :-(. No regulation whatsoever, which sucks cause then I could just consult those who regulate it.

Using an RODI in a tattoo shop?

Found this on an Ontario based tattoo website discussing water used for tattoos.

"Deionized water, also known as demineralized water[2] (DI water, DIW or de-ionized water), is water that has had its mineral ions removed, such as cations from sodium, calcium, iron, and copper, and anions such as chloride and sulfate.
Deionization is a chemical process which uses specially manufactured ion-exchange resins which exchange hydrogen ion and hydroxide ion for dissolved minerals, which then recombine to form water. Because the majority of water impurities are dissolved salts, deionization produces a high purity water that is generally similar to distilled water, and this process is quick and without scale buildup."

Sweet!!! Thanks Kentech!

If you want a real answer I'd ask a company like spectrapure. Since they are a sponsor you could start a topic in their forum and see what they have to say also.. But personally I'd think there is more savings just using the distilled water, I wouldn't think a standard rodi would be suitable for that purpose due to the fact of the price difference between ours and the lab grade ones on spectrapure 's website.

 

[RoTTen2TheCore]

Hmmm, good idea. I will look into that too. Thanks!

I would think he would need some medical grade water, nano pure water from barnstead. Otherwise, a set up that has 0.2 micron filters.

 

[johnike]

And by all means, make sure that there is plenty of moldy bread on hand.

Agreed RO/DI water is far from sterile medical grade water. We use nano pure water at work to make cosmetics and it isn't even considered medical grade.

I have an in line UV sterilizer As the first stage on my RODI unit, before it hits my sediment filter. My unit serves double duty as drinking water and for fish use. The big component is the contact time, so make sure it's sized properly.

The water should be autoclaved. That is the best and cheapest way to have it be sterile. You could also filter it past a very small filter 0.2um although for total viral elimination it should be even smaller. bacteria can easily grow in the tubing post filter. Pure water from RO/di should be put in containers that can be autoclaved. Those are then free of bacteria.
