Venturi Sizing for Ozone

[Beets]

I am debating a DIY Ozone water treatment system for treating 1 ppm H2S and bacteria (SRB's). Over the past 20 years, I have tried 1) Chlorine +GAC, 2) Air + Centaur carbon, 3) Chlorine + Centaur Carbon 4) H2O2 + Centaur Carbon. They all work. Option 2 & 4 produce the best water, but several times a year I get H2S slipping through the system due to slime and/or uncontrolled SRB's in my carbon filter. This has me thinking about Option 5 which would be Ozone + Centaur Carbon (not AIO3). My preference would be to connect an ozone generator to a single pass venturi meaning the motive fluid is from the pump in my well and not have to add a recirculation loop with pump. Based on the Mazzei charts, I'm not certain I can draw enough ozone into my water with a single pass system as my well is only 4 GPM.

It is a lot of money to spend and not know if it will work. I'm wondering if it would be wise to install a venturi in my system first, and try to measure how much gas it sucks during a pump cycle before buying an ozone generator? I was curious what others have done. Or maybe ozone isn't a DIY?

Just bumping this up to see if anyone has done sizing, and how you did it? I'm thinking of perhaps installing a venturi, attaching a 10 or 20 foot x 1/8" or 1/4" hose, introducing a gas bubble into it, and then measuring the rate at which the gas bubble moves up the hose. This should give me a good feel for the amount of air it draws in during a pump cycle.

I was curious whether you have better luck with the Mazzei or the Waterite Micronizer? I've looked at historic posts, and it seems like some people advocate for one and others advocate for another.

Another possibility is to inject peroxide with a peristaltic pump. I am not a pro.

If you do proportional injection, you can avoid creating sediment for the pressure tank. Inject downstream of the pressure tank, then have a contact+settling tank.

Neutra-Sul is a stabilized hydrogen peroxide. I don't know if that is preferable to alternatives.

Thank you. I've tried hydrogen peroxide. It (and air injection) lead to the best water, but bacteria thrive on it. I don't know why, but the chlorine never generated as good of water.
