Pilot plant technologies

The odour abatement technologies housed on the trailer include:

  • A venturi gas scrubber
  • A packed tower chemical scrubber
  • A UV oxidation system
  • A Gas phase Ozone treatment system
  • A carbon adsorption module

 

The pilot plant also incorporates several useful tools to optimise odour treatments:

  • Chemical dosing
  • Variable air flow control
  • Variable scrubbing liquor flow control
  • PH monitoring
  • Redox monitoring
  • Air flow measurement
  • Gas sampling – via inlet & outlet ports

 

The pilot plant is built on a 3.6m. x 2m. trailer platform so that it can be transported easily on the road. For local journeys between sites, the pilot plant can be moved fully rigged, as shown here. For long haul journeys, the two scrubbing towers can be dismantled and stored inside the trailer.
