Abstract/Contents

Abstract: Treatment wetlands can provide an effective barrier for waterborne pathogens. Pathways for pathogen removal and inactivation include sedimentation, predation and sunlight-mediated inactivation. Reliance on polishing wetlands for disinfection has the advantage of reducing the chemical disinfection requirements, potentially lowering operation costs, and requiring less energy than alternative technologies. The goal of this project is to provide an understanding of pathogen removal and inactivation mechanisms in treatment wetlands. Such an understanding is necessary to explain observed removal efficiencies of pathogens, as well as to provide better approaches and strategies on actively managing treatment wetlands to enhance disinfection performance.
