Abstract
PROCESO DE DIGESTION ANAEROBIA, EN DOS FASES, DE FANGOS PROCEDENTES DE LA DEPURACION DE AGUAS RESIDUALES CON CONTENIDO ORGANICO. EL INVENTO SE CARACTERIZA POR LA SEPARACION DE LA FASE ACIDOGENICA Y LA FASE METANOGENICA, COLOCADAS DICHAS FASES EN SERIE Y EN EL ORDEN INDICADO, FIJANDOSE EL TIEMPO DE RETENCION DE LA FASE ACIDA EN EL PUNTO DONDE SE ALCANZA SIMULTANEAMENTE LA ESTABILIZACION DE LA MAXIMA CONCENTRACION DE ACIDOS VOLATILES PRODUCIDOS Y LA ESTABILIZACION DEL MINIMO VALOR ALCANZADO POR EL PH, CON LEVE TENDENCIA AL ALZA, COINCIDIENDO ESTE PUNTO CON UN PERIODO INFERIOR A TRES DIAS, CONSTITUYENDO EL FANGO EFLUENTE DE ESTA FERMENTACION ACIDA UN SUBSTRATO RICO EN NUTRIENTES PARA LA FASE METANOGENICA CON SUFICIENTE ALCALINIDAD, SIENDO EL TIEMPO DE RETENCION TOTAL DE LA FASE ACIDA Y METANICA INFERIOR A LOS QUINCE DIAS, MANTENIENDOSE LA FASE ACIDA A TEMPERATURA AMBIENTE, PUDIENDOSE OPTIMIZAR CON MANTENIMIENTO DE LA FASE ACIDA CON TEMPERATURAS PROXIMAS A LOS 20 C, Y MANTENIENDO CONSTANTE LA TEMPERATURA DE LA FASE METANICA ENTRE 28 C Y 36 C.
