Biomar is a well-known aqua feed supplier on the international fish feed market. In the factory in Brande in Denmark they produce fish feed on two extruder lines. All the smelly air coming from the dryers and coolers is joined together into a plenum, and is blown into the atmosphere through a very high chimney.
Aqua feed odour control
This high chimney alone proved not sufficient to comply with the very strict Danish legislation. What’s more, the neighbourhood was complaining about offensive odours. Biomar then decided to face their responsibility and control the aqua feed odours with non-thermal plasma technology.
One compact Aerox-Injector
Biomar compared the two possible odour control solutions in detail: in-line non-thermal plasma, which would take relatively much space, or the compact Aerox-Injection technology. The final decision was to treat all the air coming from the dryers with one Aerox-Injector.
