This technical note presents some preliminary results obtained with the use of hydrophobic and hydrophilic
tensiometers to measure liquid pressures in three-phase systems (air-NAPL-water). The porous tips of the hydrophobic
tensiometers underwent a surface treatment known as silanization. The silanized tensiometers demonstrated l...
This work studied the transport phenomena in the soil of the Gramacho MSW landfill located in Rio de Janeiro,
Brazil. A model was proposed to determine the mass transfer rate of the leachate contaminant ions to the soil particles.
Previous researchers have focused on the diffusion and sorption phenomena using simple relations tha...
It is commonly accepted that the shear strength of Municipal Solid Waste (MSW) is enhanced by the
reinforcement effect of its fibrous constituents. However, most papers in the technical literature do not systematically
evaluate the effect of the MSW fibers on its stress-strain-strength response. This paper presents results of a s...
The use of Permeable Reactive Barriers (PRBs) for in situ remediation of contaminated groundwater represents
an attractive technology for both economic and operational reasons. A reactive medium widely used in PRBs is the
Zero-Valent Iron (ZVI) which, in several case studies, has proved highly efficient for the removal of both in...
