Abstract

A fluid evaporation system includes a housing bounding an airflow path. A misting system is positioned within the airflow path for spraying a wastewater into the airflow path. Water in the misted wastewater is evaporated, thereby concentrating minerals in the wastewater. A pretreatment system is positioned upstream from the fluid evaporator. The pretreatment system includes a gas induced separator. Separation of hydrocarbons and water are enhanced using a polymer and/or by lowering the pH of the wastewater.
