Abstract (en)
[origin: WO8701057A1] An electrode arrangement for use in dewatering and consolidating a fine suspension comprises an upwardly extending porous boundary wall (14) for a body of suspension to be dewatered and adjacent the boundary wall (14) at least one upwardly extending electrode (16) adapted to form part of an anode/cathode system. The electrode arrangement is used in a method of dewatering a body of suspension wherein it is provided at a boundary of the body of suspension and a dewatering electric power supply is applied across the at least one upwardly extending electrode (16) of the arrangement and at least one further electrode (22) provided within the body; said supply being applied for a time sufficient to achieve a desired degree of dewatering of the suspension.
