The final effluent could then be used to raise fish. A second system is being designed to reduce the nutrient discharge from a secondary treated municipal wastewater. This system will consist of constructed wetlands with the option of producing native macrophytes, duckweed, microalgae, ornamental plants or alternately flooded and dried grasslands. Components of these two systems are scheduled for construction at the Texas Tech University cattle feedlot demonstration site near New Deal, Texas. The demonstration treatment system will accept both swine and cattle waste that is screened to separate some of the heavy solid material in the waste.
