Electrokinetic filtration in clays: theory and experiments.
The main aspects and results of some electrokinetic filtration tests are presented. Both theory and tests show the key role played by the electrochemical boundary phenomena, such as the electrode reactions, and by the mineralogy of the soil. The aforementioned results show the necessity to run long duration tests. Indeed the macroscopic properties of the soil can change widely during the tests, therefore affecting the expected results in terms of environmental remediation or consolidation but also in terms of energy consumption and efficiency.
