Case Study1

  • The positioning of this hazardous waste was upstream of main important water well.
  • A BBR system was placed at this severely hazardous toxic waste dump, at their seepage water treatment plant, with remarkable results using only in situ microbes.
  • The BBR bio filter is ideal for extreme problem odours since the fully enclosed reactor effectively deals with variations in volatile organic compounds over a wide range of temperatures. The unit test was at the main hall where the raw waste was extracted. The trial filter size was 3,500 CFM.
  • Remarkable results were achieved on a wide spectrum of toxic waste from the raw air escaping over a number of years dating back prior to WW2.
