Abstract

This paper examines the significance influence of the operational condition such as current density (60 A/m2 to 780 A/m2), treatment time (5 min to 60 min) and pH (5 to 10) on the elimination of colour from Pulau Burung Municipal Landfill leachate which is saline in nature. A laboratory scale batch reactor was conducted using Aluminium electrode in a parallel-monopolar arrangement directly connected to the DC power supply (60V/5A) to increase the performance of the electrocoagulation reactor. The initial value of colour and salinity leachate electrolyte is 8427 Pt-Co and 15.13 ppt respectively was identified before the treatment process. The key influence of natural salinity leachate in this research is current density was observed at 540 A/m2, treatment time at 60 min, optimum pH at 8 and the total colour removal obtained was up to 71%. The empirical findings in this study provide insights on the potential of utilizing electrocoagulation process as a viable option to remove highly colored leachate with adequate salinity without ancillary to the electrolyte.
