Odour removal at animal rendering plants
Many people has experienced the characteristic and very unpleasant smell from animal rendering plants. It is a huge problem for the local community unless the smell is removed effectively.
An effective solution requires covering of open tanks and vessels, proper ventilation system inside production halls in order to obtain a slight vacuum, so all smelly air can be captivated and let into a BBK biofilter.
BBK has excellent references from many installations and is able to remove the bad smell completely.
The 2 BBK filters in the foreground can each handle 60.000 m3 foul air/h from production halls. The filters are enclosed using soft PVC covers mounted with a short stack in the center.
