Anaerobic sewage treatment: state of the art, constraints and challenges
Abstract The interest in high-rate anaerobic (pre-)treatment of sewage using UASB reactors is steadily growing since its introduction in the mid-1980s. Today there are hundreds of full-scale plantsExpand

Production and characterization of scum and its role in odour control in UASB reactors treating domestic wastewater.
There are few studies in the literature that have aimed at characterizing the physical, chemical, and microbial aspects of scum produced in UASB reactors. In addition, there is little information onExpand

Methane and hydrogen sulfide emissions in UASB reactors treating domestic wastewater.
The release of CH(4) and H(2)S in UASB reactors was evaluated with the aim to quantify the emissions from the liquid surfaces (three-phase separator and settler compartment) and also from theExpand
