Decolorization and Removal of Cod and Bod from Raw and Biotreated Textile Dye Bath Effluent through Advanced Oxidation Processes (aops)
In this paper, a comparative study of the treatment of raw and biotreated (upflow anaerobic sludge blanket, UASB) textile dye bath effluent using advanced oxidation processes (AOPs) is presented. The AOPs applied on raw and biotreated textile dye bath effluent, after characterization in terms of COD, colour, BOD and pH, were ozone, UV, UV/H2O2 and photo-Fenton. The decolorization of raw dye bat...

در این مطالعه، عملکرد دو سیستم اکسیداسیون شیمیایی پیشرفته و یک سیستم بیولوژیکی برای حذف آموکسی سیلین در فاضلاب های سنتزیدر غلظت های مشابه با موارد صنعتی مورد بررسی قرار گرفته شدند. مطالعه انجام شده دارای سه بخش متفاوت اکسیداسیون با ازن و اشعه uv، اکسیداسیون با استفاده از نانو فتوکاتالیست tio2 و استفاده از بیوراکتور هوازی لجن فعال با جداکننده های فیزیکی می باشد. در هر بخش، متغیر های متفاوتی متنا...
15 صفحه اولArtificial neural network modeling for decolorization of textile dye effluent
Introduction Effluents from the textile industry are not only colored but also contain large amounts of color, COD, BOD and dissolved solids. Textile industry is the one producing huge amount of wastewater. Due to stringent environmental regulations, treatment is mandatory before discharge the effluent. Conventional treatment methods include activated carbon adsorption, solvent extraction, chem...
متن کاملOzone for Color and COD Removal of Raw and Anaerobically Biotreated Combined Industrial Wastewater
ozonation was carried out for decolorization and coD removal of raw and anaerobically treated uAsb (upflow anaerobic sludge blanket) combined industrial (mainly textile) effluent in a lab-scale bubble column reactor. ozonation of anaerobic bioprocess effluent at a dose of 300 mg/h for 10 min resulted in 81% color and 75% coD removal (100 mgo3/80 mg coD) while for raw wastewater 25 min ozonation...
متن کاملDecolorization of Cationic and Anionic Textile Blue Dyes from Aqueous Solution with Advanced Oxidation Process Using H2O2 and Various Catalysts
In this study, we used advanced oxidation process (AOP)for the removal of a cationic and anionic blue dyes, namely Basic Blue 3 (BB3) and Acid blue 62(AB62), from aqueous solutions. Fenton reactions are mixture of H2 O2 and Fe2+. However this paper investigates the application of twelve different catalysts such as: FeCl2 , FeSO4, (NH4 )Fe(SO4 )2 , FeCl3 , Nano iron (Fe0 ), Fe(NO3 )3 , K2FeO4 , ...
