Introducción— En los últimos años, se ha incrementado la atención a la presencia de “contaminantes emergentes” en aguas residuales urbanas, industriales y cuerpos de agua superficial. En la mayoría de los casos, estas sustancias, corresponden a contaminantes que aún no ha sido reglamentados a nivel nacional por las autoridades ambientales. Los hospitales son considerados como la mayor fuente de estos compuestos, resultado de diferentes actividades. No existe en la actualidad un consenso sobre cuál o cuáles son los tratamientos adecuados para tratar las aguas residuales que contienen estos compuestos. En general, los procesos biológicos convencionales por sí solos no alcanzan a cumplir con los valores de los límites de descarga, siendo necesario aplicar postratamientos como los Procesos de Oxidación Avanzada (POA), conocidos como una tecnología apropiada no sólo por aumentar la biodegradabilidad de los compuestos recalcitrantes, sino también por contribuir con la remoción de ciertas sustancias que son difíciles de tratar en un proceso biológico. Objetivo— Por tal razón, en este estudio se evaluó la aplicación de Ozono (O3 ) y O3/H2O2 al efluente de un Reactor Anaerobio de Flujo Horizontal y Biomasa Inmovilizada (RAFABI). Metodología— Los oxidantes fueron aplicados en un reactor de vidrio de borosilicato tipo batch en escala de laboratorio. El tiempo de reacción fue de 60 min y se tomaron muestras a intervalos de 15 min. Para evaluar el desempeño del tratamiento se midieron parámetros tales como la absorbancia a una longitud de onda de UV254, la relación de biodegradabilidad expresada como DQO/DBO5, y el color como VIS436. Todas las muestras fueron analizadas por duplicado. Resultados— Los resultados mostraron que la aplicación de O3 y O3/H2O2 produjeron un incremento en la biodegradabilidad del 25% y del 67% respectivamente. En relación con el color, se observó una eficiencia del 85 % para el Ozono y el 100 % para el O3/H2O2. Adicionalmente, los dos POA aplicados también mostraron ser efectivos para remover orgánicos aromáticos medidos como UV254, para lo cual se obtuvieron remociones entre el 40% y 50% de UV254. Conclusiones— Finalmente, es importante mencionar que la aplicación de procesos de oxidación avanzada como postratamiento de efluentes anaerobios, aumentan la biodegradabilidad principalmente por la transformación que sufren los compuestos recalcitrantes. |

En la mayoría de los casos, estas sustancias, corresponden a contaminantes que aún no ha sido reglamentados a nivel nacional por las autoridades ambientales. Los hospitales son considerados como la mayor fuente de estos compuestos, resultado de diferentes actividades. No existe en la actualidad un consenso sobre cuál o cuáles son los tratamientos adecuados para tratar las aguas residuales que contienen estos compuestos. En general, los procesos biológicos convencionales por sí solos no alcanzan a cumplir con los valores de los límites de descarga, siendo necesario aplicar postratamientos como los Procesos de Oxidación Avanzada (POA), conocidos como una tecnología apropiada no sólo por aumentar la biodegradabilidad de los compuestos recalcitrantes, sino también por contribuir con la remoción de ciertas sustancias que son difíciles de tratar en un proceso biológico. Objetivo— Por tal razón, en este estudio se evaluó la aplicación de Ozono (O3 ) y O3/H2O2 al efluente de un Reactor Anaerobio de Flujo Horizontal y Biomasa Inmovilizada (RAFABI). Metodología— Los oxidantes fueron aplicados en un reactor de vidrio de borosilicato tipo batch en escala de laboratorio. El tiempo de reacción fue de 60 min y se tomaron muestras a intervalos de 15 min. Para evaluar el desempeño del tratamiento se midieron parámetros tales como la absorbancia a una longitud de onda de UV254, la relación de biodegradabilidad expresada como DQO/DBO5, y el color como VIS436. Todas las muestras fueron analizadas por duplicado. Resultados— Los resultados mostraron que la aplicación de O3 y O3/H2O2 produjeron un incremento en la biodegradabilidad del 25% y del 67% respectivamente. En relación con el color, se observó una eficiencia del 85 % para el Ozono y el 100 % para el O3/H2O2. Adicionalmente, los dos POA aplicados también mostraron ser efectivos para remover orgánicos aromáticos medidos como UV254, para lo cual se obtuvieron remociones entre el 40% y 50% de UV254. Conclusiones— Finalmente, es importante mencionar que la aplicación de procesos de oxidación avanzada como postratamiento de efluentes anaerobios, aumentan la biodegradabilidad principalmente por la transformación que sufren los compuestos recalcitrantes.Introduction— In recent years, the “emerging pollutants” in urban, industrial, and surface water bodies have called the attention worldwide. In many cases, these substances correspond to pollutants that have not been yet regulated by the environmental authorities. Hospitals are considered the main source of these contaminants as a result of different activities. However, there is no consensus about the appropriate treatments for removing this kind of pollutants in the wastewaters; independent conventional biological processes do not reach the desirable values of discharge limits. Advanced Oxidation Processes (AOP) are known as an appropriate technology, not only to improve the biodegradability of recalcitrant compounds, but also to contribute to the removal of certain substances that are difficult to treat during the biological process. Objective— Thus, this study evaluated the application of O3z and O3 /H2O2 to the effluent of an Anaerobic Horizontal Flow Reactor and Immobilized Biomass (HAIB). Methodology— The oxidizers were applied in a labscale batch borosilicate glass reactor. The reaction time was 60 min and samples were taken at intervals of 15 min. Parameters such as absorbance at UV254, biodegradability ratio expressed as COD/BOD5, and color as VIS436 were measured. All samples were analyzed in duplicate. Results— The results showed that the application of Ozone and O3/H2O2 results in an increase in the biodegradability of 25% and 67% respectively. Concerning color, an efficiency of 85 % for Ozone and 100 % for O3 /H2O2 was observed. Besides, the AOPs applied also showed their effectiveness in removing aromatic organics, removing 40% to 50% of UV254. Conclusions— Finally, it is important to mention that the application of advanced oxidation processes as a posttreatment of anaerobic effluents increases biodegradability mainly due to the transformation suffered by recalcitrant compounds.10 páginasapplication/pdfengCorporación Universidad de la CostaColombiahttps://revistascientificas.cuc.edu.co/ingecuc/article/view/3425Application of O3 and O3 /H2 O2 for post-treatment of Horizontal-Flow Anaerobic Immobilized Biomass (HAIB) effluent, treating hospital wastewaterAplicación de O3 y O3 /H2 O2 como postratamiento del efluente de un reactor anaerobio de flujo horizontal y Biomasa Inmovilizada De Flujo Horizontal (RAFABI) tratando aguas residuales hospitalariasArtículo de revistahttp://purl.org/coar/resource_type/c_6501http://purl.org/coar/resource_type/c_2df8fbb1Textinfo:eu-repo/semantics/articlehttp://purl.org/redcol/resource_type/ARTinfo:eu-repo/semantics/publishedVersionhttp://purl.org/coar/version/c_970fb48d4fbd8a85INGE CUC[1] A.
