The discussion will address differences in flow back and produced water quality and compare with requirements for hydraulic fracturing formulations. Various recycling methods will be discussed to achieve specifications for reuse in a given type of hydraulic fracturing fluids, such as slickwater, linear gel and cross-linked gel formulations. Recycling methods addressed will range from chemical coagulation and flocculation, lime softening and various mechanical methods such as dissolved gas flotation, hydrocyclones, to media and membrane filtration systems.
