EN Because the application of pressure in electro-dewatering of wastewater sludge (and consequent compression) affects processes of electroosmosis and electrophoresis, the study aimed at determining the effect of vacuum and constant electric field on the specific resistance of sludge and quality of filtrate. It was found that both the current intensity and direction affects the biogen content in sludge dewatering filtrate. An increase in the intensity of the current applied to the filtering barrier was accompanied by an increase in the effectiveness of the removal of ammonium nitrogen (filtering barrier as an anode) and orthophosphates (filtering barrier as a cathode). A constant electric field was shown to considerably affect the specific resistance of sludge filtration.
