Abstract: One embodiment of a method of water treatment comprising straining fractionated water to remove particles larger than one micron in diameter, decanting the strained fractionated water to remove surfactants and oil, evaporating the decanted water to provide concentrated brine and water vapor, and condensing the water vapor.

Abstract: A system for treating fractionated water from an oil and gas well. The system comprising a filter system, a diffusive membrane system, a plurality of membrane sensors, and at least one membrane controller. The filter system is fluidly connected to the diffusive membrane system, wherein the filter system comprises a plurality of straining filter banks. The diffusive membrane system comprises a plurality of membrane banks each having an inlet and an outlet. The plurality of membrane sensors are positioned at the outlet of each of the plurality of membrane banks, and the plurality of membrane sensors are configured to detect the total dissolved solids level at the outlet of each of the plurality of membrane banks.

Abstract: In accordance with one embodiment, a method for treating fractionated water produced by a hydraulic fracturing process is provided. The method includes decanting a fractionated water stream in at least one decanter. The decanter is maintained at a temperature ranging from about 90° F. to about 120° F. The method also includes flashing the decanted water in at least one first flash tank and at least one second flash tank in fluid communication with one another to provide a residual concentrate stream. The first flash tank is operated at a temperature ranging from about 180° F. to about 200° F. and the second flash tank is operated at a temperature ranging from about 140° F. to about 160° F. Both the first flash tank and the second flash tank are maintained at a vacuum pressure. The method also includes evaporating the residual concentrate stream in at least one evaporator kettle to produce a concentrated brine.
