Various methods and systems are provided for electrokinetic dewatering of suspensions such as, e.g., phosphatic clay. In one example, among others, a system for continuous dewatering includes a cake formation zone including a first anode and a first cathode each extending across a first portion of a separation chamber; a cake dewatering zone including a second anode and a second cathode; an inlet configured to supply a dilute feed suspension comprising solids suspended in water to the cake formation zone; and a conveying belt extending between the first anode and the first cathode and between the second anode and the second cathode. A first electric field between the first anode and the first cathode forms a cake on the conveying belt by consolidating the solids, and a second electric field between the second anode and the second cathode dewaters the cake on the conveying belt.
