Abstract
An electrode assembly for use in dewatering a suspension of solids in which an electric field augments an applied vacuum includes a chamber having ion-pervious walls on which a cake of solids is deposited and an electrode element within the chamber immersed in an electrolyte; the surface area of the ion-pervious walls being substantially greater than the surface area of the electrode element.
Claims10
An electrode assembly for electrically augmented vacuum filtration of a suspension of solids in a carrier liquid, which comprises,
- an external non-conductive frame member,
- an internal non-conductive frame member slidably fitting within said external frame member and thereby defining top, bottom and two side walls of an electrode chamber,
- ion-pervious filter elements forming the remaining two side walls of an electrode chamber so that said electrode assembly can be immersed in said suspension of solids,
- at least one electrode element within said electrode chamber electrically connected to a voltage source external of said electrode chamber and immersed in an electrolyte having a high conductivity,
- the ratio of the total area of said ion-pervious filter elements immersed in said suspension of solids to the total area of said electrode element immersed in said electrolyte being at least 2:1 and no more than 350:1.
