This document discusses a project that uses produced water from Utah's hydraulic fracturing industry to grow microalgae in a Rotating Algal Biofilm Reactor (RABR). The microalgae is then converted to bio-crude oil via hydrothermal liquefaction (HTL). Trials were conducted rotating the RABR disks at 1 rpm and 2 rpm to optimize energy consumption. Statistical analysis found the rotation speed and disk position were significant factors, with 1 rpm showing higher microalgae yields. The resulting bio-crude oil has a composition and energy content comparable to petroleum crude. A techno-economic assessment found integrating microalgae cultivation with wastewater treatment reduces environmental impacts.
