I posted this to bionet.technology without success so I'm trying here!

I am involved in trying to set up a post doc research project based on 
novel methods of treating water and wastewater.  One aspect of this is 
the  possibility that ultra sound may have a useful role to play in 
reducing microbial levels without the production of byproducts as 
produced by chemical disinfection.  

Ultra sound can quite happily bust open parasites and bacteria but what 
about viruses?  Has anyone any information on the survival of viruses 
(and other microorganisms would be helpful) when sonicated.

The application of ultra sound in water and wastewater treatment seems to 
have not been widely used - is this because nobody has thought of it, 
it's too expensive or does it not work?  Any info would be welcome.  I 
have come across one reference to ultrasound being used on a full plant 
scale somewhere in the southern US (site not named).  Has anyone any data 
on such plants?
