CSO Kombi-Skrub - Model BTF -Bio Trickling Filters

A media bed provides a home for the bacteria and gives good mass transfer of H₂S gas and other compounds from the gaseous phase to the liquid phase where the bacteria can easily consume them. Water is trickled from the top of the vessel contain the media bed, counter-current to the air entering from the bottom of the vessel, causing the air to being forced into prolonged contact with the bacteria film. The atomised water also has contact with the air, causing the gaseous compounds to dissolve in the water and giving the bacteria additional access to them.
