On the mass transfer in a sprinkled biofilter
- 38 Downloads
The mass transfer from a water film to fixed fill grains (Rashig ring) has been investigated. It has been revealed that the film regime of flow is characterized by incomplete flow over the surface of Raschig rings. The mass transfer coefficient and the portion of the washed surface depending on the flow rate of water have been measured. The process of mass transfer in a freely falling film has been simulated, and a comparison between the theoretical and measured values of the mass transfer coefficient has been made.
