Abstract
– La industria del jean requiere una gran cantidad de agua para su producción, generando una gran cantidad de aguas residuales. En promedio, el impacto ambiental de estos efluentes líquidos es alto, debido principalmente a la gran variedad de materia prima, reactivos y sustancias químicas toxicas utilizadas en el proceso.
La biofiltración es una tecnología utilizada en el tratamiento de aguas residuales, esta consiste en el uso de materiales biodegradables como filtro con la finalidad de depurar efluentes provenientes de diferentes actividades, entre ellas, la producción textil.
El presente trabajo pretende verificar la eficiencia de depuración de los siguientes parámetros: Demanda Biológica de Oxigeno DBO5, Demanda Química de Oxigeno DQO, Solidos Totales ST y Biodegradabilidad; mediante la utilización de un biofiltro vertical construido a base de una cama de turba, arena de rio lavada y piedra pómez.
Si bien existe literatura variada sobre biofiltros en la industria textil, no existe investigación específica acerca de filtración y tratamiento de aguas residuales provenientes del lavado de jeans.
Para este efecto, se realizó el monitoreo del biofiltro durante 36 días, con análisis continuos de los parámetros antes mencionados. Al final, se obtuvo una eficiencia del DBO5 de 75.27% y del DQO de 79.69%, una relación de biodegradabilidad DBO5/DQO de 0.78, y también, una reducción de solidos totales ST del 57.33%, sugiriendo la posibilidad de utilizar este biofiltro.
