I performed a rinser validation 3 weeks ago. This is something we performed as a requirement for our contractors. We are a co-packer for some customers.
They want us to achieve a 3 log reduction from that study. It has to be in normal operating conditions.
For example, 100 bottles a min, with a concentration of 0.35 of hach reading in your ozonation (this is hypothetically).
You will have to inoculate the bottles with a bacillus to a 10^5 concentration, pass it thru the rinser, collect the bottles, plate it and count the results.
As easy process, just a long one.
