Monitoreo a escala de real de un digestor anaeróbico de bajo costo instalado en una planta de sacrificio animal

Abstract

Slaughterhouses generate an average $6,5$ kg of manure/animal. Day. The animals has a weight between $350$ and $400$ kg. Manure causes economic, environmental and legal problems for the slaughter companies. The aim of this work, was to stabilize the $5,5\%$ of cattle manure of FOGASA Slaughterhouse by means of low cost digester. The results show organic matter reduce of $60\%$ volatile solid and an average biogas production of $0,9Nm^{3}/d$. During anaerobic digestion process efficiencies were reach in terms of biogas production rate, specific biogas production and reduction of the pathogen content of $0,21m_{biogas}^{3}/m_{digestor}^{3}d$ y $0,20m_{biogas}^{3}/KgSV$ y $90\%$ respectively. The digestate contained nitrogen, phosphorous and potassium, which is an important feature of fertilizers.
