AB  - In the present work, the use of high power ultrasound as a process tool for the 
      removal of persistent organic pollutants (POPs) from soil and the treatment of 
      bauxite red mud waste from the Bayer process is discussed. Laboratory scale 
      experiments have confirmed that the application of high power ultrasound to 
      slurries of contaminated soil and of bauxite ore can treat two major 
      environmental problems cost-effectively. Destruction rates of POPs in soil of 90% 
      and higher have been achieved whereas 85% iron oxide has been extracted from red 
      mud waste leaving a low-iron fraction of approximately 50% by weight which is 
      more environmentally friendly. A 4x4 kW pilot plant capable of treating 2.5 
      tonnes of slurry per day has been commissioned to provide more accurate estimates 
      of power and energy requirements to allow scale-up to industrial use.
