 Ozone for pasterization?

i will be working with an ozone genorator very shortly,, and was wondering if placeing a bale of hay, along with a tub of manure/compost, under a tarp with the ozone pumping away would be an effetive method of pasterization.
does anyone see any problems that could occure (i'm aware of ozone harmfulness to lungs)

As long as the concentrations are high enough in all areas, I don't know how to test for that but you can smell the ozone. It's my understanding that the ozone is more effective in the presence of some moisture so the material shouldn't be too dry. Perhaps you can run the ozone through some water with a bubble stone (?). I'd spend some time doing a search on google.

please be very careful with the O3.. at low altitude it is quite dangerous..

Why is it more dangerous at low altitude?

Ozone is an excellent method of purification, It will kill any bacteria and many viruses on contact. Los Angeles uses ozone to puify their entire water supply along with several othe major cities. The harmful efects are only present if ozone is inhaled due to the burning/searing of the lung tissue. Fortunately the extra electron in ozone is loosly held and is thrown off quickly leaving only oxygen. Because of this, a bale of straw under a tarp would never recieve enough of a concentration to affect it. You could however, use the ozone gengerator in combination with an air pump to pump the ozone gas into a drum filled with water and straw for a couple of hours. This would be effective. Same principle as the large water purification plants, or the new swimming pool purifiers that use ozone instead of chemicals.

You could ozonate the water first and then dump the straw in. There's a fairly new product from WaterPik which creates ozonated water that can be used as a germacidal agent that is faster acting than chlorine but leaves no chemical residue. It is recommended for spraying on kitchen counter tops and other such places.
Here are a couple of links which should answer some questions...

Low altitude in this case is anything near the ground. highist point on earth is ~9km, the highist concentration of O3 is spread from 15-35km with peak at ~25km.
now, please keep this in mind:
"Some vendors suggest that these devices have been approved by the federal government for use in occupied spaces. To the contrary, NO agency of the federal government has approved these devices for use in occupied spaces. Because of these claims, and because ozone can cause health problems at high concentrations, several federal government agencies have worked in consultation with the U.S. Environmental Protection Agency to produce this public information document." - EPA literature
O3 is an oxidant, and must be kept away from anything which oxidizes easily or harmfully.. such as living things..
if you use one of these in any way indoors or in a constrained environment (outside is still not a great idea unless you have good airflow.. which could cause problems with attaining sterialization) you will easily exceed the acceptable levels. Many products have been tested indoors and the levels were all dangerous within an hour, and this test with air circulation equivalent to a "standard" or "average" duct based air conditioning/heating system.
there are other, better, ways.
since your attempting to sterialize (not pastureize.. you would effectively be nukeing anythign alive, not selectively killing off some competitors) a product which is somewhat porus, not a liquid, and with a rather complicated surface, O3 is not even a great choice for disinfection.
"Even at high concentrations, ozone may have no effect on biological contaminants embedded in porous material such as duct lining or ceiling tiles (Foarde et al, 1997). In other words, ozone produced by ozone generators may inhibit the growth of some biological agents while it is present, but it is unlikely to fully decontaminate the air unless concentrations are high enough to be a health concern if people are present. Even with high levels of ozone, contaminants embedded in porous material may not be affected at all. " - EPA
also keep in mind that the sites you (evolving) linked to are by companies which sell product which use ozone. It is in their interest to selectively chose what they tell you.
at a junkyard you should be able to pick up a non reactive drum (make sure it is marked as free of any contaminants!! you dont want a dirty radioactive waste or an old PCB drum..) for cheap.. propane burner for it is ~50.. you can do a bale at a time that way..
good luck, and please be careful..
dont forget you could be killing off alot of other living things you may not want to die in whatever area you use, should you chose to use O3..

yeah, maybe thats why he said to pasturize, not sterilize.
read what people say first before correcting them by telling them exactly what they had just posted.

hehehe, you might wanna take a closer look at what i said...:)
anyway, i'd be interested in hearing about your experiments and how they go.
Good luck!
