Larger Test. Scientists are not sure exactly what takes place when the sewage is subjected to the combination of buzzes and bubbles. But whatever happens is highly effective. Clumps of bacteria and viruses disintegrate; longer chemical molecules break apart. In a pilot project at the University of Notre Dame that processes 20,000 gal. of sewage daily, less than 60 seconds of Sonozone treatment has proved itself capable of destroying 100% of the fecal bacteria and viruses it attacks, 93% of the phosphates and 72% of the nitrogen compounds...
