Subsoil decontamination with bioventing: numerical experiments
A mathematical model describing the bioventing technique for the decontamination of pol-
luted subsoil will be presented. Bioventing is a biological technique: bacteria remove the
contaminant transforming it and oxygen is consumed in the reaction. The numerical model
is based on the fluid
flow theory in porous media and bacteria population dynamics and
it describes: pollutant degradation, oxygen and bacteria concentration. The mathematical
model will be numerically solved and the results of some experiments will be presented.
