Photocatalytic oxidation of laundry industry wastewater using TiO2 as catalyst and UV1 light

The treated effluents are wastewater supplied by a laundry industry, using photocatalysis technology with artificial sources of radiation (UV lamps), TiO2 as a catalyst and a composite parabolic trough cylinder (CPC). Industrial wastewater was used with the aim of starting an investigation with real...

Industrial wastewater was used with the aim of starting an investigation with real liquid effluents and not with synthetic mixtures prepared in the laboratory, what is sought with this project is to take a first step towards the use of these new technologies on an industrial scale . The experimental results were statistically processed by response surface model, taking the catalyst concentration, pH and recirculation time, as the parameters that affect the final concentration of COD (Chemical Oxygen Demand), the response variable chosen. A maximum degradation without H2O2 of 26.49% and with the addition of H2O2 of 41.8% was achieved.Los efluentes tratados son aguas residuales suministradas por una industria de lavandería, utilizando la tecnología de fotocatálisis con fuentes artificiales de radiación (lámparas UV), TiO2 como catalizador y un foto-reactor cilindro parabólico compuesto (CPC). Se empleó agua residual industrial con el objetivo de comenzar a efectuar una investigación con efluentes líquidos reales y no con mezclas sintéticas preparadas en el laboratorio, lo que se busca con este proyecto es dar un primer paso hacia la utilización de estas nuevas tecnologías a escala industrial. Los resultados experimentales fueron procesados estadísticamente por modelo de superficie de respuesta, tomando la concentración del catalizador, pH y tiempo de recirculación, como los parámetros que afectan la concentración final de DQO (Demanda Química de Oxígeno), variable de respuesta escogida. Se logró una degradación máxima sin H2O2 del 26,49% y con adición de H2O2 del 41,8%.application/pdfspaUniversidad EAFIThttp://publicaciones.eafit.edu.co/index.php/ingciencia/article/view/493http://publicaciones.eafit.edu.co/index.php/ingciencia/article/view/493Copyright (c) 2005 Edison Gil PavasAcceso abiertohttp://purl.org/coar/access_right/c_abf2instname:Universidad EAFITreponame:Repositorio Institucional Universidad EAFITIngeniería y Ciencia; Vol 1, No 2 (2005)Photocatalytic oxidation of laundry industry wastewater using TiO2 as catalyst and UV1 lightOxidación fotocatalítica de aguas residuales de la industria de uso utilizando TiO2 como cataquífera y luz UVarticleinfo:eu-repo/semantics/articlepublishedVersioninfo:eu-repo/semantics/publishedVersionArtículohttp://purl.org/coar/version/c_970fb48d4fbd8a85http://purl.org/coar/resource_type/c_6501http://purl.org/coar/resource_type/c_2df8fbb1Advanced OxidationPhotocatalysisPhoto-OxidationCodWastewaterUvTitanium Dioxide ProcessesProcesos Avanzados De OxidaciónFotocatálisisFoto-OxidaciónDqoAguas ResidualesUvDióxido De TitanioGil Pavas, EdisonUniversidad EAFITIngeniería y Ciencia122540ing.cienc.ORIGINALdocument (2).pdfdocument (2).pdfTexto completo PDFapplication/pdf201415https://repository.eafit.edu.co/bitstreams/514c3174-4086-47f7-b26e-96e561c65408/downloadaa7297904ee5ecded893d7bd4fe3ceb8MD52articulo.htmlarticulo.htmlTexto completo HTMLtext/html373https://repository.eafit.edu.co/bitstreams/54636045-0d64-45e5-b9d7-90d37c9115a9/downloadfe8b63701aaf72b0449ab79a9f431a80MD53THUMBNAILminaitura-ig_Mesa de trabajo 1.jpgminaitura-ig_Mesa de trabajo 1.jpgimage/jpeg265796https://repository.eafit.edu.co/bitstreams/1de23cd5-35de-44f2-b568-7079a4802f7e/downloadda9b21a5c7e00c7f1127cef8e97035e0MD5110784/14569oai:repository.eafit.edu.co:10784/145692020-02-11 20:42:33.878open.accesshttps://repository.eafit.edu.coRepositorio Institucional Universidad EAFITrepositorio@eafit.edu.co
