Bursting bubbles kill water bugs

UK scientists have developed a water treatment system which they hope could cut the risk of Legionnaire's disease, and aid people in the developing world.

The system, developed by Coventry University researchers, kills bugs using bursting bubbles.

Work so far has shown it can make water pure enough to wash in, or for animals to drink.

The team developing the device hope it could one day be used to make water pure enough for people to drink.

Sounds good, hope it works.

1. They should start experimenting in Iraq ASAP

I bet they're willing to try just about anything to purify their water over there. It's better than nothing, and it might help. Lord knows they need all the help they can get after bush "helped" them.

2. pretty clever

I hope it works.

And it makes me wonder, how did they think of this?

The system is a pipe with a narrow middle section. As water passes through this section, it hits a pin which helps create bubbles,

As the water passes into the second wide section of the pipe and the pressure falls the bubbles collapse, setting off chemical and physical effects, killing bacteria.

'No chemicals'

Adrian Marsh, director of Stats said: "You get extremely high pressure points, and a very high temperature, at a very local, molecular, level.

"We think the reason the device has these 'biocidal' effects, is that the cell walls of the bacteria are fractured."

5. So, does that mean it's safe to drink the water in a jaccuzi? Cool!

3. Just wait until PETA hears what they are doing to the little buggers n/t
