Abstract
  • Wetlands, whether constructed or manmade, have been widely used in wastewater treatment methods as they are efficient water purification systems and nutrient sinks. A constructed wetland is a sustainable and environmental friendly option for the treatment of domestic wastewater because it is affordable, reliable, easy to operate and offers control over design and operating conditions at the point of wastewater generation. It can be designed to remove total suspended solids, pathogens, heavy metals, organic pollutants and reduce oxygen demand of the treated water and has been demonstrated to remove pharmaceuticals and personal care products with comparable efficiencies to that of conventional wastewater treatment plants. However, the land requirements and high water retention times often make the treatment process slow. This report suggests engineering modifications to an existing system at Jordan Lake Business Park that would potentially improve the effectiveness of the constructed wetland in removal of traditional pollutants and pharmaceutical compounds with the purpose of directly using the treated effluent for agricultural land applications.
