Abstract
A solid-liquid mixture is electro-dewatered by apparatus having a conveyor belt for receiving an electric charge and having the mixture deposited thereon and an element above the conveyor belt receiving an opposite electric charge with the conveyor belt an element cooperating to apply a compressive force to the mixture and characterised by the conveyor belt including discrete electrically conducted segments which are permeable to the liquid. The upper element is preferably in the form of a rotary drum or second conveyor belt but it can be in the form of a pressure plate.
