Pasteurization units

Pasteurization tanks

As standard, Bigadan designs biogas plants with pre-pasteurization steps, where the biomass is heat treated at 70°C (158°F) for 60 minutes before degassing giving the following advantages:

  • Observing EU's bi-product directive 1069/2009
  • 10-20% increase in gas output
  • Increased dehydration for degassed biomass/sludge

Additionally, Bigadan's pasteurization tanks are used at commercial sewage treatment plants for sludge pasteurization. We handle all aspects of the tank construction, including design, erection and commissioning.
