Abstract
Systems and methods for treating wastewater with an oil-specific viscosifier composition and separating viscosified oil, undissolved solids and/or particulates, and/or other waste materials in such wastewater are provided. The methods further include: providing wastewater that includes oil; mixing the wastewater with an oil-specific viscosifier composition to form a viscosified oil; and separating at least a portion of the viscosified oil from the wastewater to provide treated water.
