A study has been conducted on a retention soil filter (RSF) to test its effectiveness in removing pharmaceutical residues and microorganisms from combined sewer overflows (CSOs). ...
In this study, adsorption and degradation of four selected PPCPs, metronidazole, tinidazole, caffeine and chloramphenicol, have been investigated in the laboratory using two agricultural soils in China and sediment from Changjiang River. Adsorption tests using a batch equilibrium method demonstrated that adsorption of all tested chemicals in ...
Therefore, batch studies have been conducted to characterize the sorption and desorption behavior of ivermectin in three European soils (Madrid, York, and artificial soil). The solid-water distribution coefficient (Kd) for ivermectin sorption to the tested soils were between 57 and 396 L kg–1 (determined at 0.1 µg g–1), while the ...
Laboratory tests were used to determine geotechnical and physicochemical properties and mineralogical composition. The results of a range of laboratory tests, including oedometer types, filter paper, triaxial, and new stainless steel tank apparatus, showed the problems associated with investigating swell behavior of soils. A field swelling ...
Data were collected and reviewed pertaining to one-dimensional vertical free-swell tests performed on existing fill soils from various projects located in Southern California. The purpose of reviewing the data was to evaluate the effect of overburden pressure on the swelling potential of expansive soils. The swell tests were ...
Kmax)n, can be used.In this research, the parameters, A and n, were predicted by a viscoelastic approach. Uniaxial tensile creep tests were performed, and the creep versus time data were represented by means of the generalized power law, D(t) = D0 + D2tm. This power form represents the creep response of soil cement much better than the pure power law, D(t) = ...
