“…The rates of H 2 O 2 decomposition and COD removal depended primarily on pH, initial H 2 O 2 dose, and Fe 0 surface area concentration. Since aeration rate controlled the DO level, it was an essential factor for the enhanced treatment, in agreement with our previous finding [4]. High aeration rate apparently inhibited the H 2 O 2 selfdecomposition, perhaps partially replaced H 2 O 2 to promote yield of the principal ROS, and accelerated the oxidation of organic compounds.…”

“…H 2 O 2 was measured by the titrimetric method [6]. The homogenized sample of 0.03 mL for total iron analysis was digested and diluted as described previously [4]. Total iron was measured by flame atomic absorption spectrometry (Analyst 800, PerkinElmer).…”

“…landfill leachate (50% reduction of COD), based on the hypothesis that the direct introduction of H 2 O 2 to the IMA process can enhance the oxidation. In addition, 38% of electrical conductivity was reduced due to precipitation, and 83% of ammonia nitrogen was removed by air stripping when the pH was controlled within an appropriate range [4]. In the enhanced IMA process, COD removal efficiency is influenced by iron source, pH, H 2 O 2 dose, and aeration rate.…”

“…Although a high energy consumption and a potential chlorinated organic formation may limit its application, electrochemical oxidation is a promising and powerful technology for the treatment of landfill leachate as was also stated by Deng and Englehardt in 2007 [26]. In general, it is reasonable to consider that electro-oxidation makes sense when renewable energy is used.…”

This paper examines the efficiency of electro-oxidation used as the single pretreatment of landfill leachate. The experiments were performed on three different types of leachate. The results obtained using this electrochemical method results were analyzed after seven days of treatment. The main characteristics of leachate and a diagram of the experimental apparatus are presented. The overall objectives were to contribute to the knowledge of electrochemical treatments for the reduction of COD, BOD 5 , ammonium, and total suspended solids, and also to examine whether there was any resulting hexavalent chromium in the liquid sample. The yields obtained were considered satisfactory, particularly given the simplicity of this technology. Like all processes used to treat refluent water, the applicability of this technique to a specific industrial refluent needs to be supported by feasibility studies to estimate its effectiveness and optimize the project parameters. This could be a future development of the work.
