| contents | Dye decomposition by combined ozonation and anaerobic treatment: Cost effective technology Smita Venkatesh Kumar Venkatesh Abdur Rahman Quaff Ingeniería ozonation degradation UASB reactor decolourization Reactive black 5 To control the total treatment cost of textile dye effluent a new advanced combined treatment technology has been investigated. Advancedoxidation processes like ozonation have much potential to degrade dye but its main drawback is high cost. To reduce the cost of ozonation fordye degradation and decolourization, ozonation followed by anaerobic biodegradation using upflow anaerobic sludge blanket (UASB) reactor wascarried out. The synthetic textile wastewater containing Reactive Black 5 has been used in this study by this combined treatment process. Thesystem of ozonation and anaerobic treatment by UASB reactor showed that the chemical oxygen demand (COD) reduction has reached to about90% and dye removal 94% respectively. Combined treatment enhanced the overall color removal up to 10 on platinum cobalt (Pt–Co) scale. Thusthe combined treatment process results in high color, COD and total organic carbon (TOC) removal efficiency which would minimize the overalltreatment cost. Dye degradation products were analyzed by ion chromatography (IC) and UV–vis spectroscopy. 2017 artículo científico 1665-6423 https://www.redalyc.org/articulo.oa?id=47452572004 https://www.redalyc.org/journal/474/47452572004/ https://www.redalyc.org/journal/474/47452572004/html/ https://www.redalyc.org/journal/474/47452572004/47452572004.epub https://www.redalyc.org/journal/474/47452572004/movil en http://www.redalyc.org/revista.oa?id=474 Journal of Applied Research and Technology application/pdf Universidad Nacional Autónoma de México Journal of Applied Research and Technology (México) Num.4 Vol.15 |
