ABSTRACT

 

In this work the electrochemical (EC) process is used as a pretreatment step for the treatment of distillery wastewater using iron plates as electrodes in a batch EC reactor. The maximum COD removal of 56% was achieved at a current density of 0.10 A cm−2 with 140 min of electrolysis time at wastewater pH of 3. The BOD to COD ratio increased from 0.15 to 0.52 indicating improvement in wastewater biodegradability. The maximum anodic efficiency observed was 2.68 kg COD h−1A−1m−2 with a corresponding energy consumption of 0.71 kWh kg−1 COD.
