Treatment of hydraulic fracturing wastewater by wet air oxidation

Abstract: 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 fracturing wastewater. The experiments used different values of flocculant, coagulant, and oxidizing agent added to the wastewater, as well as different reaction times and treatment temperatures. The use of flocculants for the pretrea… Show more

“…Studies have been conducted for produced water treatment using technologies such as microbial capacitive deionization, , electrodialysis, , filtration and osmosis, distillation, , adsorption, and oxidation. , However, most of these methods are generally focusing on the overall salinity and/or total organic carbon removal, and very few studies have specifically examined the selective bromide removal for DBP control purposes. Sun et al investigated the use of aerated electrolysis on selective bromide oxidation using graphite electrodes .…”
