The current and most practiced stimulation of unconventional gas reservoirs is hydraulic fracturing. This treatment is based on pumping a hydraulic fluid into the horizontal wellbore (up to 5000-7000 meters deep) at a high pressure to a value greater than the breakdown pressure of the formation and thus creation of conductive for shale gas fractures.

This study aims to generate a clean brine with low suspended solids, ,iron,, and organic matter, which can be reused onsite for hydraulic ,fracturing, process. Reuse of produced water can significantly reduce the current freshwater consumption during unconventional oil and gas exploration, and decrease the volume of produced water for deep well disposal.

The disposal and leaks of hydraulic ,fracturing, wastewater (HFW) to the environment pose human health risks. Since HFW is typically characterized by elevated salinity, concerns have been raised whether the high bromide and iodide in HFW may promote the formation of disinfection byproducts (DBPs) and alter their speciation to more toxic brominated and iodinated analogues.
