5. Sizing reactive permeable barriers
The use of BPRs requires knowledge of a large number of parameters such as :
the water flow to be channelled to the filter doors ;
Hydraulic characteristics of filters ;
filter retention capacities ;
screen dimensions ;
hydraulic characteristics of the screen ;
the presence or absence of a watertight bedrock.
This requires detailed site characterization.
A particularly important element is to understand the heterogeneity of flows and the pollution plume. Flow rates and directions are generally not uniform, and vary according to contrasts in subsoil permeability. In the case of an alluvial water table, for example,...
