Part A: Advances in tools and techniques for estimating biogas production and treatment in anaerobic-based STPs Technical Note 1 - Topics of interest

Abstract

The management of biogas in sewage treatment plants (STPs) with anaerobic reactors is still a challenge in Brazil. Problems related to odor, corrosion, occupational risks, energy losses, and even to greenhouse effect, are still a reality. The problems related to the energetic use of biogas from UASB reactors are mainly associated with the presence of hydrogen sulfide (H2 S) and humidity, as well as fugitive biogas emissions, which make it difficult to accurately estimate biogas production. In this sense, this Technical Note (TN) aims at addressing the main aspects related to biogas production estimate and biogas treatment in STPs with UASB reactors. This contribution derives from the experience of experts and professionals of the academic and water utility sectors, as well as from the specialized literature. The topics of interest are summarized in this TN, the first of this collection, “Valoration and management of gaseous by-products of sewage treatment. Part A: Advances in tools and techniques for estimating biogas production and treatment in anaerobic-based STPs”, being individually detailed in the following Technical Notes that integrate the collection.
