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.

An absorption cycle system, which permits water heating, dehumidifying, and/or evaporative cooling, includes a desorber, absorber, heat exchanger, and, optionally, an evaporator, is constructed to heat a process water that is plumbed through the absorber, heat exchanger, and condenser. In the absence or isolation of the evaporator, the system can dehumidify ambient air to the absorber. The water vapor released by evaporative cooling at the evaporator can be provided to the absorber in a controlled manner to simultaneously maintain a desired humidity while cooling the air ambient by the evaporator. The absorption cycle system can be housed within a single unit or can be compartmentalized.
