Pilot-scale petroleum refinery wastewaters treatment systems: performance and microbial communities' analysis
Published 2020“…The reduction of the COD, BOD5, phenols, and the total petroleum hydrocarbon (TPH) reached 82.10%, 85.87%, 91.63%, and 81.11%, respectively at high hydraulic residence time (HRT = 10 days). Decreasing HRT to 5 and 2.5 days led to a decrease in the efficiency of the process and a decrease in biomass concentration was also observed (<1000 mg/l). …”

Evacuation under flooded conditions: Experimental investigation of the influence of water depth on walking behaviors
Published 2021“…To propose guidelines for evacuation planning during floods and to develop simulation tools, which can be used in evacuation planning, empirical data are needed under different flooding conditions. However, there is a lack of data and studies on such aspects. This study examines the influence of water depth on human walking behaviors under hydrostatic conditions using the data collected through a controlled laboratory experiment. …”
