Mainstream P-recovery can help wastewater treatment plants (WWTPs) to effectively maintain good enhanced biological phosphorus removal (EBPR) while helping to recover P. In this study, a pilot-scale anaerobic-anoxic-aerobic (AO) process was operated for simultaneous COD/N/P removal and P-recovery under different operational conditions. [...]

Despite the increasing number of studies related to the polyhydroxyalkanoate (PHA) production from sewage sludge of wastewater treatment plants, there is still a gap in the correlation between the operational conditions, such as the organic loading rate (OLR), and the intracellular polyhydroxyalkanoate (PHA) content, productivity and final recovery of the polymer.

Sewage sludge management is known to cause odour impact over the environment. However, an information gap exists about odour emissions quantification from different treatment strategies. In the present work, odorous emissions generated in a full-scale sewage sludge composting plant were characterized, aiming at providing specific odour emission factors (OEF) and to determine their variability depending on the composting time.
