Abstract (English): The problems associated with contamination of untreated sludge, due to the volumes of these wastes generated in wastewater treatment plants, are described. These affect the environment due to its content of organic matter, microorganisms and heavy metals. The aim of this work is to perform a review of existing regulations for the management of sludge or to make possible its application in soils and the treatment technological processes that are applied to reduce its environmental impact. The current standards for the proper management and reuse of sludge, establish strict control over heavy metals and microbiological contamination. The technological processes employed can be physical (such as centrifugation, filtration and drying), chemical (which include lime stabilization, conditioning and chemical disinfection) or biological (such as anaerobic and aerobic digestion). Among these, the most used are the biological ones followed by dehydration of sludge by drying. Similarly, it is recognized that there are other available technological such as ozonation, which allows to obtain reduction efficiency of the indicators of physical–chemical and microbiological pollution between 31and 99, 99 %, as well as 90 % of volume.

Abstract (Spanish): Se plantea la problemática relacionada con la contaminación de los lodos sin tratar, debido a los volúmenes de estos residuos que se generan en las plantas de tratamiento de aguas residuales. Estos afectan al medio ambiente, por su contenido de materia orgánica, microorganismos y metales pesados. El objetivo del trabajo es realizar una valoración sobre las normativas existentes para el manejo de los mismos o su aplicación en los suelos y los procesos tecnológicos de tratamiento que se aplican para disminuir su impacto ambiental. Las normas vigentes para el manejo y reuso adecuado de los lodos, establecen un estricto control sobre los metales pesados y la contaminación microbiológica. Los procesos tecnológicos de tratamientos empleados pueden ser físicos (como la centrifugación, filtración y secado), químicos (que comprenden la estabilización con cal, el acondicionamiento y la desinfección química), o biológicos (como la digestión anaerobia y aerobia). Entre estos los más empleados para la estabilización de los lodos son los biológicos, seguidos de la deshidratación de los lodos mediante su secado. De igual forma, se reconoce que existen otras tecnologías disponibles como la ozonización, la cual permite obtener eficiencias de reducción de los parámetros indicadores de contaminación físico-químico y microbiológico entre un 31 y 99,99%, así como un 90% de su volumen.
