ABSTRACT
The paper is focused on the influence of anode flushing on physicochemical conditions in the anode compartment and anode stability during the electrodewatering in electrofilter press. Kaolin suspensions were dewatered in laboratory filter press with stainless-steel electrodes at electric current density of 80 A/m2 and pressure of 2 bar. Two electrodewatering methods were compared: conventional (with filtrate drainage) and innovative (with continuous anode flushing using electrolyte solution). Flushing with neutral electrolyte solution significantly reduced the electrochemical anode corrosion, and can be suggested for the improvement of anode lifetime through a better control of physicochemical conditions during electrodewatering.
