ABSTRACT:
A method and apparatus for discharging a cake of suspended solids formed on an electrode structure, the electrode structure comprising an electrode, a membrane wall, an electrolyte chamber formed by the membrane wall, and means for increasing the pressure inside the electrolyte chamber so that the membrane wall expands, whereby the cake of solids of suspension are discharged therefrom. The means for increasing the pressure inside the electrolyte chamber are injecting gas into the electrolyte chamber, injecting liquid into the electrolyte chamber, and/or reducing the vacuum means applied internally to the electrolyte chamber.
