VOC advanced pretreatment before adsorption treatment in an odor treatment line - Azurair® Cool

Azurair Cool - Aquaviva WWTP, Cannes France
Enhanced removal of Volatile Organic Compounds (VOCs)

The Azurair® Cool process is an optimized water scrubber dedicated to VOC’s removal. It uses the capacity of cold water to maximize the solubility of VOCs in a water scrubber and to dehumidify air flow before its entering an activated carbon filter.

The Azurair® Cool includes:

  • A gas scribber, consisting of a packed column operating in counter current mode without liquid recirculation.
  • A cooling unit to cool the washing water.

key figures

  • 60% less waste*
  • 10% reduction in energy consumption on the air treatment line
  • 55% less CO2 eq emission*

*Compared to a conventional VOC treatment (adsorption on an activated carbon filter

profit
  • Reduced environmental footprint compared to conventional VOC treatment
  • Odor removal twice as effective as conventional VOC treatment
  • High performance: as an example, the VOC removal is improved by more than 30% when the washing water temperature is reduced by 7°C
  • OPEX savings: reduction of activated carbon replacement frequency.
