Polluted Air Treatment

Biofilters are used for the biological removal of air pollutants which are are toxic, have an unpleasant odour, or are of environmental concern. BioScrubTM is registered trademark of Osorno and a third generation biofilter. The design of BioScrubTM combines an aerobic thermophilic treatment process with state-of-the-art electronic control.

Osorno has long history of designing biofileters. To learn more about biofilters, read our famous Rumours and Facts; it is as true today as it was when it was written in 1994.


The BioAer® aeration floor is a “green product”, it is made of 100% recycled plastic. Aeration floors are perhaps the most important component of biofilters and composting facilities, because it is not trivial to convert the incoming strong horizontal air flow into an even vertical air flow, which however is the condition for high efficiency of the biofilter.

On the other hand, this product can be used for many unrelated applications, such as an elevated floor in data centres, in greenhouses, in sludge handling and drying units, as a floor system for animal facilities, or for industrial catwalks, etc. These floor plates are very robust and are capable of bearing high loads.
