Anyone running ozone?

[apollothesun]

Not in this state. You have to keep in mind we use these for the hobby but generally they are fed pure oxygen in order to get 100% of the rated output.
You dont need anything fancy for a dryer. You can use a addon di cartrige and replace the di resin with drier. You just cook it in the oven after it is used up.


Don

cool, thats what i'll do.

In smaller systems its a good idea. I use this gizmo so it makes it real easy to have carbon both the exhaust and output.

awesome piece of equipment. how do you hook this up to your system?

I'm pushing ozone through a pyrex difuser column I got from ozone labs it uses what they call a destructor for the excess ozone.

. These units are kinda new to me. Some do use cupric oxide or titanium oxide and or rare earth elements. The most common one in use from a search is manganese dioxide and is what Ozone Solutions and what Ozone Labs uses.

UV is/can be used to make O3 or destroy O3 also.

Ozone destruct systems use a catalyst to decompose ozone or at thermal unit. In short they convert ozone (O3) to oxygen (O2), same for the UV. However, with that said how can it work for you ? O3 in seawater has a half-life of only a few seconds. It is not O3 you get in seawater unless it is unbromided seawater, like some public aquariums use or use to use. Can this unit convert the bromine back to bromide ? I don't see how it can do that.

Catalyst
A material that increases the rate of reaction without any reaction taking place. Thing car; you do not need a catalytic converter if you just made your tail pipe longer. However, since it is not the catalytic converter speeds up the production of water and CO2, so you pass EPA stds.

Heat also cause faster conversions. For example in 1980 Pontiac had a Limited Edition Turbo-Charged Trans-Am. With a catalytic converter it did not meet EPA std, so they just rapped the catalytic converter in an blanket asbestos like material to increase the heat conversion, thus it then passed EPA

Now that you have read my rant here I have some bad news for you ;( There is not such thing as a destructor for the excess ozone other than GAC or UV for water. When you are dealing with something wet, like a media in water, it is another world to destroy ozone with one of these units in water. Catalytic action is almost a dry thing, as in gases in air. Yes, there are catalytic actions that take place in liquids. The unit you have is and air phase only unit. I just made a couple of phone calls to two companies that sell and make them. As of now, in time, Ozone Solutions will have one for water. Such a unit will be hundreds of dollars. What you boight/got, is a small unit used in the medical field. Your unit is destroy for off-gas ozone. However, it would wok fine for ozone leaving your skimmer vent instead of GAC.


This is what you have correct

It is for the what I guess you would call off gass or just excess that makes it out so as not to go into the room.
I have it connected to this unit which works very well.

And when any unreacted hypobromous acid finally reacts with the GAC, it's reduced back to bromide ions?

Ozone, chlorine, bromine, chloramine, broamine and their hypo's react with the carbon surface. An example

BrOH + C* ---> Br- + CO* + H+

Some of the oxidized activated carbon remains, and some breaks down to produce O2.


2CO* ---> 2C* + O2

OK. It sounded to me like you where doing a water thing. Ran the O3 gas through the diffuser and then the treated water through the destructor.

All this bromine stuff is explained in detail in the articles I posted on the first page

 

[Boomer]

And yes for the other questions, if water, you still need GAC for O3 treated water

You have to pump water through it. The vent can go outside or in carbon. It uses slow flow and very little ozone. The output can just go into a cup of carbon easily. The flow is slow so it pretty much nukes anything that goes through it. I would probably run the exhaust outside with the genx ozone mine has a real adjustment so I can turn it up and down. I did use it with a non adjustable enaly 300 but I had to run the exhaust outside.

Thanks so if I have this right, Ozone create a bromate out of the bromine in solution as hypobromous acid. And when any unreacted hypobromous acid finally reacts with the GAC, it's reduced back to bromide ions?

my heads hurts just trying to read this brings back all sorts of bad memories that I thought I left behind when I changed majors

Nope ) O3 + Bromide = Hypobromous acid + more O3 = Bromate, in short in seawater. What OPO's form is a function of pH. There is alos hypobromite, hypochlorus and 3 forms of chloramine and Boramine and all are a function of pH. Bromide can also reaction with O3 and give Bromate

Br- + O3 → BrO3-

Here is an example for Bromine and Broamines

Different forms of bromine at various pH values and various concentrations of ammonia.
