El contenido biológico de filtros anaeróbicos de flujo ascendente / [The biomass in upflow anaerobic filters]

ABSTRACT

A cylindrical upflow filter packed with non-reticulated polyurethane foam, seeded with anaerobic sewage sludge and geared to biological treatment of dairy industrial wastewater, was used to determine the biomass content of the biofilm and suspended flora. This microflora is responsible for the conversion to methane and carbon dioxide of most of organic matter in wastewater. The methanogenic process reduces the COD of liquid wastes in more than 83
