UV Dose Required by Pathogen Species

9 posts in this topic

I've been looking for a good reference on required UV zap dose required to eradicate various pathogens, and I found this great
whitepaper from Siemens Corporation. The doses are in J/M^3. Multiple by 0.1 to get the fluence in mJ/cm^2.
These are the values for log-1 reduction, or 90% reduction. For log-3 reduction (99.9%), multiple the fluence by 3.
The dosage is higher than I have seen in other literature, so I tend to believe these numbers.

Just to show how tough some of these buggers are, Chilodonella cyprini requires 30,000 J/m^3, or 3000 mJ/cm^2, or

3,000,000 uW-sec/cm^2 to reduce 99.9%. In other words, not practical to kill with UV

Most UV units report the fluence for a given flow rate in uWsec/cm^2. Just multiply the doses by 300 to get the

log-3 reduction dose in uW-sec/cm^2.

Wow so basically in order to kill 75% of the list you need 3.8w per 100l of flow.

That's massive ....

Uv's are essentially for reduction of bacteria, viruses, algae and fungus. Using them for parasites is just not practice.

Yes, Nike was founded at my university. I can walk from my desk to Hayward field where now started in about 8 minutes.
