All electrochemical experiments are conducted in the same electrochemical cell with the same apparent electrode surface and inter-electrode distance.</p> <div> <p>The three different electrochemical processes are discussed, their efficiencies compared and evaluated. The initial dye concentration of 100 mg l<sup>-1</sup> was fast and efficiently removed in only a few minutes of electroprocessing time. The electro-Fenton treatment is the fastest, most efficient and economical process operated at very low current densities of 0.33 and 0.66 mA cm<sup>-2</sup> and consuming only 4.75x10<sup>-3</sup> and 5.23x10<sup>-3</sup> kWh m<sup>-3</sup> of treated solution respectively. The electrocoagulation treatment with iron electrodes and the electrooxidation process with Ti/Pt electrodes conducted at applied current densities of 5 mA cm<sup>-2</sup> consumed 0.511 and 0.825 kWh m<sup>-3</sup> of treated solution respectively. The proposed procedure is a safe, economical and efficient method for removal of indigo carmine dye from aqueous solutions and dye house effluents.</p> </div> <p> </p> </p></abstract><publication_date><month>03</month><day>21</day><year>2014</year></publication_date><pages><first_page>499</first_page><last_page>506</last_page></pages><publisher_item><identifier id_type="pii">gnest_01330</identifier></publisher_item><doi_data><doi>10.30955/gnj.001330</doi><timestamp>1714870569</timestamp><resource>https://journal.gnest.org/publication/gnest_01330</resource></doi_data></journal_article></journal></body></doi_batch> </div>
