Anaerobic lagoon biogas recovery systems
AbstractFloating covers were placed on two anaerobic lagoons to study biogas production. One cover was approximately 370 m2 in size and was located on a lagoon receiving effluent from a poultry anaerobic digester. The second cover was 155 m2 and was located on a swine anaerobic lagoon. The liquid entering the swine lagoon had opportunity for considerable volatile solids (VS) loss prior to entering the lagoon. The poultry and swine lagoons had mean volumetric biogas production rates of 0·07 and 0·05 m3/m3-day, respectively. The areal biogas production rates were 0·16 and 0·13 m3/m2-day for the poultry and swine lagoons, respectively. The mean methane (CH4) concentrations were 64·8% and 62·0% for the biogas from the poultry and swine lagoons, respectively. Biogas production was determined to be a function of VS loading and lagoon temperature. Biogas production rates were reduced at lagoon temperatures below 13–15°C.
