Abstract |
This study examines electrochemical post treatment to remove COD, SS, K+ and Cl- from anaerobically treated sugarcane molasses vinasse (ASMV). Platinum coated titanium mesh was used as electrode material for both the cathode and anode, with 843.18 cm2 of working area. The effects of pH on removal efficiency, as well as energy and electrode consumption, were investigated. The influent ASMV was diluted 10 times and initial pH was adjusted with HCl and NaOH. The electrolysis experiment was performed at a current density of 94.88 A/m2 with 15 minutes of reaction time, and the effluent was collected after 90 minutes of settlement. Results showed that the treatment efficiency was influenced by initial pH value. The maximum COD removal efficiency (49.25%)was obtained at a pH of 5.0. For SS removal the maximum efficiency (46.27%) was obtained at a pH of 10.0, and the lowest occurred in neutral pH conditions. The maximum efficiency of Cl- removal (17.59%) was obtained at a pH of 8.2 (non-adjusted), and efficiency was lower when influent was adjusted to acidic and neutral pH conditions using HCl. Maximum efficiency of K+ removal (7.23%) occurred in neutral pH conditions and did not occur in alkaline conditions. Energy consumption was lower in pH-adjusted conditions than non-adjusted conditions, and electrode consumption was higher in either acidic or alkaline conditions relative to neutral pH conditions. |
