Method of construction of a porous medium in the study of phenomena for use

摘要

- Method of construction of a porous medium suitable for the phenomena of biodegradation. - it is introduced into a glass column a mixture of sand and earth, of a progressive manner so as to form a porous medium, the capillary network is uniform over the entire height of the column in terms of the pore size distribution. It is then totally the porous medium saturated with water, and it becomes unsaturated partially the water in a homogeneous manner, by using a microporous ceramic membrane wettable with water and impermeable to air. Finally, it is saturated, the pores is not filled with water, then it becomes unsaturated partially the oil in a homogeneous manner, by using a microporous ceramic membrane wettable to the oil and impermeable to the air. - application in particular to the study of the polluted soils or hydrocarbon reservoir.
