Abstract
Bioventing is a technology used to abate the presence of pollutants in the
subsoil.
Microorganisms biodegrade the pollutant but the biochemical reaction
requires oxygen and so an air
ow is induced in the subsoil by means of
injection and/or extraction wells.
Costs, final result and decontamination time are reliant on contaminant
type, soil permeability and several other factors, but oxygen subsoil concentration
plays a very important role. For this reason a rational choice of well
location and
ow rate is required.
The mathematical definition of the optimal design problem will be setup
starting from a simplified mathematical model describing the bioventing
system.
A formal definition of decontaminated subsoil will be given and the set of
system control variables will be identified. Several optimimization strategies
such as cost minimization, removal rate maximization and time optimization
will be mathematically described.
