Abstract

Bioventing is a technology used to remove some kinds of pollutants from the subsoil and it is based on the capability of somebacteria species to biodegrade contaminants. The biochemical reaction requires, among other things, oxygen and, therefore,oxygen is inflated into the subsoil by wells. The mathematical model describes the movement of the different fluids whichare present in the subsoil - air, water, pollutants, oxygen and so on - and the bacteria population dynamics. The presence ofsource reactive terms in the continuity equations allows the contaminant biodegradation to be described.The design of a subsoil decontamination intervention concerns bioavailability problems and, in particular, the oxygenconcentration. Therefore, in order to enhance the biodegradation phenomenon, the optimization of the subsoil oxygen velocityfield in the polluted area is required, by an appropriate choice of the well positions and of the well air inflating rates. Inmathematical terms, the goal is to obtain the decontamination of the subsoil with an optimal value of an objective function byacting on some control variables which, in this case, are the well positions and the inflating rates. In this paper several kind ofobjective function are proposed.
