Effectiveness of ozone and dwell time.

[SeanT]

I have been reading a few posts, articles that state that ozone would/may be more effectively used if not injected directly into the skimmers venturi but rather into the plumbing leading into the skimmers input.
Thus giving the ozone more dwell time.

Any thoughts on this?

Im just starting to educate myself on Ozone... Tagging along.
Just curious... why would ozone need more dwell time?

Sean.... do you currently run Ozone?

 

[SeanT]

I have been using ozone ofr almost 2 years.
Works great, just trying to see if it can work better.

Here are two good posts about ozone for you.

Thanks! I think Im sold on Ozone. Just going to read AMAP before purchasing. Still tagging along on this one, though...

I wanna try it, but does it really make the room smell?

No, if the room smells you have a problem that needs to be fixed. If you can smell it, you should assume you are being damaged by it.

With enough dwell time and low enough dosing, all the O3 should be gone before it escapes into the air. Sometimes this is from pushing too much air thru the ozonizer.

If you can't get enough dwell time to use up the O3, then you need carbon filter on the air outlet of your skimmer/reactor. In any case, you should have carbon downstream of the ozone injection to absorb any nasty byproducts.

Maybe I didn't explain my thoughts clearly enough.

What I mean is, would adding the ozone in the skimmer feed benefit the oxidation process versus adding it through the venturi due to it having longer contact time?

Ozone has a life of approximately 30 seconds after it is created. It is very unstable and wants to get rid of the extra oxygen molecule as fast as it can. So it will react rather quickly when it comes into contact with any organics in the water. I would say using the venturi to draw ozone into the skimmer will produce the same results.

Is anyone using ozone with an aqua C skimmer?
