Freshwater Recovery System for Hydraulic Fracturing (FRESH-Frac) using a Thermally-Actuated Nozzle-Demister
Project Innovation + Advantages:
Oregon State University (OSU) is developing a system for extracting clean irrigation water from hydraulic fracturing wastewater using low-grade solar or industrial waste heat. The system would efficiently separate, condense, and reclaim water vapor from wastewater using a heat-activated swirling nozzle combined with an in-line demister. OSU’s technology would be modular, portable, scalable, and deployable at a fraction of the cost of existing treatment systems. If successful, the treated water would be suitable for agricultural use, providing an abundant new water source and easing competition for this vital resource.
OSU’s system will demonstrate a module that can produce 25 kilograms per hour of irrigation water from saturated fracking wastewater.
The proposed technology can treat highly contaminated wastewater from fracking and produce gray water, irrigation water, or the clean water necessary for oil extraction in a new fracking site or other industrial uses. It can eliminate the practice of reinjecting the wastewater underground, which increases the likelihood of contaminating freshwater resources.
