Contribución para el perfeccionamiento del diseño, la construcción y la operación de reactores UASB aplicados al tratamiento de aguas residuales urbanas - Parte 2: Tratamiento preliminar, bombeo y distribución de caudal

Abstract

La etapa de tratamiento preliminar es fundamental para el adecuado acondicionamiento del agua residual antes de su ingreso a los reactores UASB. El objetivo de esta Nota Técnica es discutir acerca de los principales problemas, sus respectivos orígenes y las posibles soluciones asociadas al tratamiento preliminar, bombeo y distribución de caudal en los reactores UASB. En síntesis, un adecuado tratamiento preliminar influenciará positivamente en: i) el mantenimiento de las estructuras de distribución de caudal y canaletas colectoras de efluente, evitando obstrucciones; ii) en la reducción de sedimentación y acumulación de arena en el fondo de los reactores UASB; iii) en el manejo del lodo, de modo a obtener un material sólido con menor contenido de residuos y arena y de mejor calidad estética; iv) en el manejo de la nata, sobre todo debido a que, cuando algunos materiales no son removidos adecuadamente en el tratamiento preliminar, tienden a flotar en el interior del reactor y a acumularse en la parte superior del separador trifásico (por ejemplo: plásticos o residuos livianos en general); y v) en la reducción significativa de problemas comunes asociados a la operación de unidades de procesamiento mecanizado de lodo y nata, tal como la paralización por obstrucciones de tuberías o la falla y pérdida de rendimiento de equipos debido al desgaste.
