FIELD: technological processes; chemistry.
SUBSTANCE: method includes application of electric field between consumable electrodes rich in iron, which are inserted into soil area, deposit or sludge so that to create gradient of pH and Eh from acid to alkaline conditions and therefore to assist in spontaneous in situ deposition of stable strip rich in iron. Method may be realised with the purpose of stabilisation and/or strategic dehydration/repeated watering of soils, deposits and/or slurries, improvement of physical properties of soils and deposits for technical purposes, forced and directional migration of contaminated drainage and/or electroosmotic displacement of nonpolar contaminants.
EFFECT: method is cheap, efficient and adaptable in use.
