In the present investigation the influence of the ambient temperature on biogas production was determined. This relationship is necessary to establish, depending on the ambient temperature of each locality in which time and just installed a biodigester charged will be full of biogas.This tubular biodigesters PVC geomembrane, 8 and 12 m3 total volume (1.27 m diameter and 6.7 to 10 m in length) were used, with 6 and 9 m3 working volume, respectively, occupied by the mixture of cattle manure: water in the ratio 1: 5. Biodigesters were installed at seven locations of Amazonas, San Martín and La Libertad regions - Peru; different temperature and height above sea level. At each site the hydraulic retention time (HRT), in days, required for the biodigester bell ball and extra storage are full of biogas was determined.Based on the results obtained, the height above sea level and the volume...

En la presente investigación se determinó la influencia de la temperatura ambiente sobre la producción de biogas. Esta relación es necesaria para establecer, en función de la temperatura ambiente de cada localidad, en que tiempo un biodigestor recién instalado y cargado estará lleno de biogas.Para ello se emplearon biodigestores tubulares de geomembrana de PVC, de 8 y 12 m3 de volumen total (1,27 m de diámetro y 6,7 a 10 m de longitud), con 6 y 9 m3 de volumen de trabajo, respectivamente, ocupado por la mezcla estiércol de ganado vacuno: agua en la proporción 1:5. Se instaló biodigestores en siete localidades de las regiones Amazonas, San Martín y La Libertad – Perú; de distinta temperatura ambiente y altura sobre el nivel del mar.En cada localidad se determinó el tiempo de retención hidráulico (TRH), en días, necesario para que la campana del biodigestor y el balón a...
