Constructed wetland treatment systems (CWTSs) could provide a passive, low-energy strategy for mitigating risks associated with oil sands process-affected waters (OSPWs). Due to the large volumes (over 975 million m3), heterogeneous composition, and

Mining leases in the Athabasca oil sands (AOS; near Ft. McMurray, Canada) produce large volumes of oil sands process-affected water (OSPW) that contain potentially problematic constituents requiring treatment prior to surface water discharge into rec

Naphthenic acids (NAs) are problematic constituents in energy-derived waters, and aerobic degradation may provide a strategy for mitigating risks to aquatic organisms. The overall objective of this study was to determine the influence of concentratio

This paper describes an analysis of pressure transients in conduits that includes effects of variable conduit diameter and contrasts in fluid material properties. The analysis considers pressure applied to the outside of a submerged conduit, as well

Constructed wetlands have been used to treat contaminants, including ammonia and nitrate, with varying degrees of success; however, no study has been performed to evaluate ammonia treatment performance of a constructed wetland specifically designed t

Evapotranspiration (ET) can affect treatment performance on constructed wetlands by enhancing constituent transport through the hydrosoil where treatment reactions occur. Additionally, ET can decrease volumetric flow thereby increasing hydraulic rete

The fate and distribution of arsenic in simulated groundwater was determined in a pilot-scale constructed wetland treatment system (CWTS) designed to promote specific biogeochemical processes for arsenic removal. Two CWTS series were designed to prom

Water depth may enhance performance of constructed wetland treatment systems (CWTSs) for renovation of complex mixtures such as fresh oilfield produced waters (FOPWs) that contain constituents such as oil and divalent metals (i.e. Cd, Cu, Ni, and Zn)

Clinoptilolite was investigated as a sorptive medium for use in constructed wetland treatment systems (CWTSs) based on its affinity for ammonia and high surface area for attachment of periphytic biofilms. Results from a batch sorption experiment indi

Mining leases in the Athabasca Oil Sands (AOS) region produce large volumes of oil sands process-affected water (OSPW) containing constituents that limit beneficial uses and discharge into receiving systems. The aim of this research is to identify co
