Abstract: A system and method for treating contaminated wastewater is provided. The system and method may be used to treat wastewater such as hydraulic fracturing flowback water, which is contaminated with guar gum, similar gelling agents, or other biological polymers. The contaminated wastewater is pressurized and heated and then allowed to spend a residence time in a vessel. The process may be a continuous or a batch process.
