Electrocoagulation of a Real Malaysian Leachate Sample Using Al Electrodes to Meet Discharge Standards

Abstract

This work investigates the applicability of electrocoagulation using aluminum (Al) electrodes to treat a typical Malaysian leachate sample. The treated leachate sample well met Malaysian discharge standards in terms of chemical oxygen demand (COD) and color. Color was lowered by 72 %. To the knowledge of the authors, no earlier study on the use of Al electrodes in the treatment of a real leachate sample has been reported elsewhere. This work suggests that Electrocoagulation using Al electrodes could an efficient approach in real leachate treatment processes.

Application of electro-Fenton process for treatment of composting plant leachate: kinetics, operational parameters and modeling

“…5a, the maximum and minimum of COD removal efficiencies are related to theoretical ratio H 2 O 2 /COD = 0.1 in 5 min (22 ± 2) and 0.6 in 60 min (83 ± 2), respectively. The main reason for increasing COD removal by adding H 2 O 2 may be attributed to the generation of hydroxyl radical that plays an important role in decomposition of organic materials [41,47].…”
