Sludge dewatering is considered one of the most challenging aspects of wastewater treatment. This study aims to use electro-kinetic (EK) technology to dewater sludge. The objective is to derive the optimum conditions to potentially dewater sludge on an industrial environment. 3 experimental series were conducted on sludge with moisture content 98.8% and 92.8% using constant voltages ranging from 0V to 30V. The length between the electrodes was 10cm and 20cm and the volume of water removed and the current was measured at periodic timeframes.
