| Résumé: | Hydraulic fracturing technology is widely used for recovering natural gas and oil from tight oil and gas reserves. Large volumes of wastewater, flowback water, are produced during the fracturing process. This study examines algal treatment of flowback water. Thirteen microalgae strains consisting of cyanobacteria and green algae were examined. Wastewater quality before and after algae treatment, as well as volatile matter, fixed carbon and ash contents of the biomass grown in flowback water were examined. The experimental results demonstrated that microalgae can grow in flowback water. The chemical composition of the algal biomass produced in flowback water was strain specific. Over 65% total dissolved solids, 100% nitrate and over 95% boron reduction in flowback water could be achieved. Hence, algal treatment of flowback water can significantly reduce the adverse environmental impact of hydraulic fracturing technology and produce biomass that can be converted to bioproducts |
