Hydrodynamic and mass transfer study of the immobilized soil bioreactor
- Ecole Polytechnique, Montreal (Canada)
The process of entrapment, or immobilization, of soil particles into the pores of a geotextile membrane was studied. The immobilized soil bioreactor was used for carrying out the process of immobilization. A mathematical model of the liquid flow structure in the reactor is presented. It has been shown that soil particles with a size between 0 and 400 {mu}m can be immobilized in the geotextile membrane. The fastest immobilization was observed for particle sizes around 200 {mu}m. The profile of the surface density of immobilized soil by the reactor height was also studied. This profile can be linked to the liquid flow structure predicted from the model. The maximum surface density of immobilized soil was 2 kg /m{sup 2}. 4 refs., 5 figs.
