Abstract: A process treats a fluid stream of used fracturing fluid containing contaminants and forms a reconditioned fluid stream. Contaminants are removed by the combination of distillation, electrostatic agglomeration, decanting, and filtration or by distillation and optional filtering. Optionally, in each case, the filtered fluid stream is treated in a clay tower to remove residual contaminants.
