    Treatment of colored and real industrial effluents through electrocoagulation using solar energy
    (2013) Azam Pirkarami; Mohammad Ebrahim Olya; Sahar Tabibian
    This study was undertaken to investigate the removal of Acid Orange 2 (sodium 4-[(2E)-2-(2-oxonaphthalen-1-ylidene) hydrazinyl] benzenesulfonate) and Reactive Blue 19 (2-Anthracenesulfonicacid,1-amino-9,10-dihydro-9,10-dioxo-4-[[3-[[2-(sulfooxy) ethyl] sulfonyl] phenyl] amino]-,sodium salt (1:2)) from synthesized and real effluents through electrocoagulation using solar cells for the purpose of improving economic efficiency of the process. The impact of a number of key operating parameters was explored including current density, anode type, temperature, pH, and electrolyte concentration. The current density of 45 Am(-2) proved to be the optimum level for both dyes. The same optimum alternatives were found for the other parameters in both cases: iron anode, a temperature level of 25°C, a pH of 7, and an electrolyte concentration of 15 mg L(-1). Both effluent samples were subjected to COD (chemical oxygen demand) and TOC (total organic carbon) tests. Cost analysis was performed for the treatment process.
