This method of odor removal is based on chemical absorption. The contaminated air is led through a reactor with the help of a fan. The odor binding liquids bind the unwanted smells leaving fresh air to exit the system. These reactors can be adapted for odor removal of different quantities. This method is designed for odor removal only, it does not remove other unwanted particles and substances.
This method does not convert odors into different less odor rich form but removes all odor. The method has been successfully tested at the University of Oulu and Åbo Akademi University, and the reactors are in use in tens of different locations.
