Abstract (en)
[origin: WO2011010285A1] A sludge dewatering system that includes a reactor to apply an electric field across at least a portion of the volume of the sludge and a dewatering station to dewater the sludge. The dewatering system may include one or more bypass lines so that at a portion of volume the sludge bypasses particular stages of the system. The dewatering station may use, for example, pressing or a centrifuge.
