Desempeño del Proceso de Bioconversión en Lodos Anaerobios Deshidratados de Plantas de Recuperación de Aguas Residuales.

The major secondary waste product of municipal wastewater treatment plants is sewage sludge, which mainly consists of dewatered microbial biomass from the anaerobic digester. This sludge is disposed off by landfilling or incineration, but can also be used in agriculture after composting if there are no high contents of heavy metals and organic pollutants in sewage sludge.
