Abstract: A method and apparatus for the removal of water, liquids and liquors from sludges and slurries, the sludges and slurries mixed with an electrolyte to improve conductivity and introduced into a conveyor chamber where an electrical path is established to permit electrical energy to pass through the conveyor chamber and the sludge, slurry and electrolyte to free bound water and remove it from the sludge or slurry, and to heat the sludge or slurry to drive off remaining water by vaporization.

Abstract: A method and apparatus for dewatering material, the material having a certain degree of conductivity, the material being introduced into a pressure chamber and simultaneously being compressed as electrical energy is introduced into the material elevating the temperature and driving off the fluid or water in the form of steam through apertures in the pressure chamber, the residence time being a function of the conductivity of the material, the dimensions of the pressure chamber and the electrical energy and pressure directed on the material.
