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