In recent years, geotube began to be widely used in treatment of coastal reclamation projects. However, the dewatering of sludge in geotube is inefficient. In this paper, for improving dewatering efficiency and laying a basis for the further study of large-scale electro-osmotic dewatering in geotube, electroosmosis has been applied to silt dewatering experiments in small hangbag. By measuring the change of moisture content, electricity current, voltage and comparing with other experiments under different conditions, the following conclusions have been obtained: the electro-osmotic dewatering speed is much faster than the natural dewatering. The non-woven fabric bag is easier to dewater than the high strength fabric bag which is made by the company of Royal Tencate.
