Very high ozone dose

[norskfisk]

I have a questing for Randy or other chemistry buffs:

Say I make an external ozone reactor, with a very slow throughput, where so much ozone is mixed in that absolutely all DOC and even tiny particles are completely oxidized into inorganic state. Bascially resetting the water to pure seawater. I know that this will create some dangerous compounds. So the question is: Can the water be led into a secondary/third chamber where it is left to bubble with air for some time to get rid of those compounds? Or are they of a more permanent nature. Will it work at all, or will I destroy the seawater somehow with high ozone doses?

I don't think you will be able to remove all organic matter with ozone, even at very large amounts, unless you wait a VERY long time. Some organics are just not very sensitive to oxidation with ozone.

But if you do water to remove a lot of organics this way, you will leave a bunch of oxidants that need to be removed. GAC will catalytically remove them (and left over ozone). I not sure simple sitting will remove them in a reasonable time, but it might. Aeration won't help, IMO. But if you wait a few weeks most of them might break down.

You're welcome.

Happy Reefing.
