Abstract: A wastewater evaporative separation system can include an evaporation panel assembly and a wastewater delivery system. The evaporative panel assembly can include at least 10 individual evaporation panels laterally joined together and fluidly coupled to a body of wastewater. The evaporation panel assembly can be configured for receiving wastewater from the body of wastewater and evaporating water therefrom as the wastewater cascades down the evaporation panel assembly and contaminants generally become more concentrated. The wastewater delivery system can be associated with the body of wastewater and can include a fluid directing assembly delivering wastewater from the body of wastewater to an upper portion of the evaporation panel assembly.
