Summary

  • The water vapour emitted from cooling towers can be reduced by using plume abatement, French nuclear firm EDF has recently undertaken a trial of one such technique using electrostatic droplet capture.
  • US firm Infinite Cooling claims the technology can be retrofitted to existing plant and reduces water use, as well as minimising the visible plume emitted from the cooling towers.
  • Traditional plume abatement techniques include the use of parallel air streams and counterflow condensing modules in an air-to-air heat exchanger, while other firms offer low-profile, forced-draft cooling towers.
  • However, electrostatic droplet capture is a relatively new method of reducing water vapour emissions and could provide a cost-effective way of significantly lowering cooling water needs.
