LED Water Purifier

Step 8 Operation

To use it simply expose by partially submerging the UV LEDs to your water for about 30 seconds and your water should be good and 99.99% bacteria free.

Thanks for reading.

EDIT: ok so it turns out that the LEDs I got are not quite powerful enough but this still gives you the basic concept. I would recomend that you get some 240nM UV LEDs they will raise the budget but it is worth it.

So, you claim that the water will be 99.99% bacteria free.  Have you tested that hypothesis with bacterial cultures?

Surely the LEDs do not need to actually be IN the water. So long as the container doesn't filter UV light you could surely put the UV LEDs OUTSIDE the container.

Would be interesting to test this with proper cultures on petri dishes. Shame I don't have a lab / money / the scientific experience to do it...

:( May not have been the case when you posted that link but it's now showing as 'out of stock'

Your device does not kill bacteria:

1 - UVC is germicidal, thats between 100 and 280nM
2 - most plastics and glass filter out UV light

You need to use Clear poly-styrene plastic or cobalt glass for UVC to pass through, or stick the bulbs into the water without anything infront of them.

it kills the bacteria sure but some water would still taste like S***

If it does indeed nuke 99.99%, how awesome would it be to rig it for solar/rechargeable battery operation! Then rig it, all nice n compact, onto a cap for a 2 gallon plastic container. Cool!
