Hydraulic performance of zero-valent iron and nano-sized zero-valent iron permeable reactive barriers – laboratory test

Annals of Warsaw University of Life Sciences - SGGW. Land Reclamation, 2014
Abstract Hydraulic performance of zero-valent iron and nano-sized zero-valent iron permeable reactive barriers - laboratory test. The hydraulic conductivity of zero-valent iron treatment zone of permeable reactive barriers (PRBs) may be decreased by reducing the porosity caused by gas production and solids precipitation.
