For the batch electrocoagulation, the reactor made up of
plastic material with the dimensions of 14cm x 9cm x 15cm
was used. The working volume of the reactor was 1L. The EC
unit consisted of four iron electrodes connected as bipolar
system in the reactor and DC power supply. The dimensions
of the electrodes were 5cm x 5cm x 1mm. The schematic
representation of the experimental setup is shown
