A design approach for constructed wetlands for storm water and point-source wastewater treatment

Proceedings of the 2003 Georgia Water Resources Conference, held April 23-24, 2003, at the University of Georgia.Constructed wetlands can mitigate ecological risks to aquatic receiving systems by decreasing concentrations and toxicity of contaminants associated with storm water and point-source wastewater. This paper describes an approach to constructed wetland design for treatment of copper and biochemical oxygen demand (BOD). In constructed wetland microcosm systems, total copper was decreased from 46 mg/L to 12 mg/L (73% removal). Five-day BOD decreased by >50% (approximately 20 mg/L to
