In the area of odour removal, two different cold atmospheric plasma technologies are used.
In the first alternative the odour-destroying effect of the plasma is based on electron dissociation (by microplasma or magnetic organized plasma source). Thereby highly reactive electrons immediately destroy at their point of origin - the plasma source – malodorous molecules by breaking up their chemical bonds. The smell destruction by electron dissociation is 10,000 times faster than the conventional ozone dissociation.
Areas of application of electrode dissociation:
- Installation of air-permeable, compact plasma sources in extractor hoods in households as well as in the gastronomy and industrial sector
- Installation of air-permeable large plasma sources in exhaust systems in agriculture (elimination of farmyard malodours) or in air-conditioning systems for indoor air conditioning
- Planar, small plasma source for removing odours in textiles/clothing, e.g. a small, mobile and battery powered device for travelling
- Planar, large plasma source for removing odours in household textiles such as carpets or seating furniture etc.
A second alternative is the activation of water vapor with reactive plasma species by combining high humidity with the plasma components in order to benefit from the advantages of plasma-activated air and plasma-activated water. Compared to plasma-activated air, the activation in water vapor can be maintained for a longer time. The result is an increased efficiency regarding the smell destruction.
Areas of applications of plasma-activated water vapor:
- Combination of a plasma source with already existing steam appliances to destroy odours in textiles (e.g. irons or steam cleaners)
- Combination of a plasma source with already existing evaporators to destroy odours in the air (e.g. humidifier)
