Oil sands process water (OSPW) is generated in high quantities during the extraction of the bitumen from the oil sands. Naphthenic acids (NAs) are recalcitrant compounds, corresponding more than 50% of all organics in OSPW. The efficient management of OSPW is of importance to guarantee efficient...

Biochar is a stabilized carbon with porous structure that can be used as an economical adsorbent for wastewater treatment. Since there are numerous types of biochars, it is important to understand how biochar characteristics influence adsorption performance by selecting or customizing biochars...

Water contamination by ammonium ions presents huge risks to the ecosystems. This work evaluated the potential application of digested sludge pyrolyzed biochar on ammonium removal. Anaerobic digester sludge was collected from a municipal wastewater treatment plant in Alberta, Canada and pyrolyzed...

Portland cement is the most widely used binder in construction. However, the production of Portland cement emits a large amount of CO2, and one strategy to decrease such anthropogenic CO2 emissions is to reduce the amount of Portland cement produced by partially replacing it with supplementary...

Biochar incorporation into soils influences many of the soil’s physical/chemical properties. The potential of using biochar for reclamation of saline-sodic soils is not well evaluated. Furthermore, how salinity would influence Phosphorus (P) sorption capacity of biochar is not clear. The main...

Land reclamation of oil sands disturbed boreal forests in Alberta is a challenging task facing companies with surface mine leases. The government requires reclamation to equivalent land capability, which is a vague statement at best. Agronomic theories and methodologies have been applied in the...

The increasing abundance of per- and polyfluoroalkyl substances (PFAS) has attracted growing interest due to concern about the potential hazards to public health and ecosystems. Due to PFAS toxicity, mobility, environmental persistence, and strong bioaccumulation, they are being further...

The objective of this 6-month pilot experimental study was to test the ability of biochars derived from Alberta biomass and an oil sands petroleum coke to remove selected organic acids from water. To this end, we selected one biochar produced from wheat straw and made by the Alberta Biochar...
