Lead Removal from Soils via Bench-Scale Soil .Deze pagina vertalen

The efficiencies of six washing solutions in removing lead from the contaminated soils were then investigated via batch washing experiments. Unlike conventional field-scale soil washing, all particle size fractions were washed and recovered in these bench-scale experiments. HCl and EDTA obtained the best Pb-removal efficiencies.

Soil washing, on-site, off-site - Plambeck .Traduire cette page

Our „ContraCon-soil washing procedure" is one of the wet mechanical processes. The basic principle of its mode of action is the removal of the harmful substances from the soil particles by inducing mechanical energy. The solution medium in this case is water and small amounts of biologically short term degradable surface-active substances.

Comparison of Ultrasonic and Conventional .

The effect of ultrasound on the conventional mechanical soil-washing process was investigated. To determine the optimal frequency for maximum efficiency, tests were conducted with aluminum foils under four frequencies including 35, 72, 110, and 170 kHz. It is known that the physical effects generated during acoustic cavitation damage the foil by causing pits and holes.

25/05/2015 · Soil washing was the main technique, treating around 700 000 m 3 of soil by mixing it with water. This removed the fine grained fractions on which the contaminants were predominantly based, creating a filter cake, typically around 20% of the total volume of soil washed.
