Substrate utilization kinetic models in the semi-dry thermophilic anaerobic digestion of municipal solid waste.
No full textA kinetic study of the thermophilic anaerobic digestion of the organic fraction of municipal solid waste (OEMSW) sorted in an industrial plant is carried out. Two kinetic models are used to form the basis of the study: one is the first-order model and the other is the step-diffusional model proposed by the authors. Estimated kinetic constants are compared to those obtained in mesophilic conditions. © 1992, Taylor & Francis Group, LLC. All rights reserved

Fast digester start-up under mesophilic conditions using thermophilic inoculum
No full textThe paper deals with fast procedures adopted for starting-up anaerobic digesters treating biological wastes. In particular, results related to the behaviour of a digester treating sewage sludge with a fast start-up (in 22 days) and using a thermophilic inoculum are presented and compared with those related to a passage from mesophilic to thermophilic temperatures (from 37 to 55°C, in 31 days) and to a direct re-start-up under thermophilic conditions (27 days). In the latter cases, the organic fraction of municipal solid wastes was digested. Main findings concern: the identification of two retention times as the necessary period for reaching the first steady-state condition; the usefulness of performing a real time process monitoring the observation that thermophilic inoculum allows better digester performances in the first start-up period, a finding however, that requires more experimental work
