Dans la gestion des sols contaminés, la notion de biodisponibilité des polluants des sols est fréquemment évoquée comme permettant d'optimiser l'évaluation du risque sanitaire. Toutefois, une certaine confusion existe entre les notions de biodisponibilité et bioaccessibilité des polluants dans les sols. Cela engendre des difficultés pour, d'une par...
Centrifugation, filtration, PCS, ICP-MS, AAS, SEM and EDX were compared to each other to characterize the inorganic colloids in the Elbe river. The ICP-MS and AAS-analysis of fractions obtained by centrifugation was found to be the most appropriate combination of methods. Thus the water of the Elbe river at Dresden contains inorganic colloids besid...
Land reclamation measures involve soil conditioning for the intended purpose (agriculture, forestry, conservation, tourism, recreation etc.) and in accordance with the given initial conditions of the soil. This research project covered the period of 1999-2002, with the following goals: Construction and testing of a small-scale test system for produ...
Disintegration processes were investigated which had been proved in laboratory experiments to intensify sludge digestion, with the intention to obtain industrial-scale operation experience and data required for a comparative analysis. In order to exclude seasonal or procedural variations, all experiments were carried out in a single communal sewage...
