Soil washing as a potential remediation .

Soil washing is frequently an effective means of treating some types of contaminated soils by concentrating the contaminants in a smaller volume of soil and enabling the larger soil volume to be returned to the original site as clean fill. This technology is well established and has been extensively used in Europe for a number of years for remediating large quantities of contaminated soil ...

Soil Washing - edie

Soil washing is a technique that separates and cleans contaminated soils and can be used to clean up a variety of organic and inorganic contaminants such as hydrocarbons, metals and pesticides. It can reduce the volume of contaminated soil requiring disposal by up to 90% and enables the cleaned soil to be re-used as an engineered fill on site.

An efficient method was developed for treating polychlorinated biphenyl (PCB)-contaminated soil by soil washing and subsequent TiO2 photocatalytic degradation, and the photocatalytic degradation mechanism of PCBs was explored. Hydroxypropyl-β-cyclodextrin (HPΒCD) and polyoxyethylene lauryl ether (Brij35) were used to extract PCBs from contaminated soil at first, and then the degradation of ...

Soil Remediation by Washing Flowsheet. One method for soil remediation is soil washing. As illustrated in the flowsheet below, soil washing supplies mechanical energy and water to liberate contaminants from the surfaces of soil particles, and separates the more highly contaminated fines from coarser soil particles to reduce the volume of material requiring further treatment.
