fracturing fluid is water (>90%), followed by prop,pants (<10%), and additives (,0.5 – 2%)., After the for mation has been fractured the pressure is released from the well which causes the fluid mixture to flowback to the surface. This fluid is generally classified as either flowback or produced water [2]. Flowback water is commonly defined as the
