A method and device for removing water from normally difficult to filter suspensions, such as sludge wherein the suspension is disposed in a container having a negatively charged cathodic screen bottom surface and a moveable anode screen specially disposed within the suspension from the bottom cathode surface, together with means for controlling the electric potential between the anode and cathode, as well as the distance therebetween such that the water or other effluent can be removed through the cathode screen bottom surface leaving a cake of higher solids content. Additionally, means is provided for removing the cake formed between the cathode and anode from the suspension and continue the removal of water therefrom, while the cake is out of the suspension environment.
