This study demonstrates the potential of an activated sludge mixed liquor to degrade guar under typical ,flowback, conditions [i.e., high concentrations of total dissolved solids (TDS)]. Guar was efficiently degraded at a TDS concentration of 1500 mg/L, with more than 90% of the dissolved ,chemical oxygen demand, (,COD, d) having been removed after 10 h.

Wastewater, produced by hydraulic fracturing for oil and gas production is characterized by high salinity and high chemical oxygen demand (COD). We applied a combination of flocculation and wet air oxidation technology to optimize the reduction of COD in the treatment of hydraulic frac,turing wastewater.

Hydraulic ,Fracturing, is the process of transmitting pressure by ,fluid, or gas to create cracks or to open existing cracks in hydrocarbon bearing rocks underground. The purpose of hydraulic ,fracturing, an oil or gas reservoir is to enable the oil or gas to flow more easily from the formation to the wellbore, a process known as stimulation.
