The European Soil Data Centre ESDAC is the thematic centre for soil related data in Europe Its ambition is to be the single reference point for and to host all relevant soil data and information at European The effectivenes of soil washing is based on the fact that most organic and inorganic contaminants tend to bind preferentially to clay silt and organic soil particl In the washing process the fine clay and silt particles are separated from the coarser sand and gravel soil particl The separated fines and contaminants are dewatered into a

Solution pH is another important factor determining the efficiency of a washing because it can influence the soil s retention of metals by adsorption Peters and affect the capability of chelating agents to extract the contaminants from soil through different mechanismsHigh efficiency washers are more expensive than standard washers and the purchase price should be weighed against the operating costs for your family You can save money by choosing models that have fewer options like steam cycl

Abstract The physical treatment with respect to soil washing is an established technique for cleaning contaminated soils Its basic principle is the removal of the fine particle fraction from the soil material in which the contaminants are predominantly concentratedArai studied the effect of concentration and kind of detergent and the impact of oil on soil removal efficiency in hard water He found that there was a linear relationship between concentration of detergent and water hardness at maximum soil removal efficiency This relationship was dependent on the nature of the oily soil and kind of detergent In his study Cameron
