This article provides an update on the wastewater treatment technologies, which utilize natural processes or passive components to remove various pollutants. The focus is on the wetland systems and their applications in wastewater treatment (as an advanced treatment unit or a decentralized system), and nutrient and pollutant removal (heavy and hazardous metals, industrial and emerging pollutants including pharmaceutical and personal care products and endocrine disrupting chemicals). A summary of studies involving the effects of vegetation, wetland design and operation, modeling, hybrid and innovative systems, storm water treatment, sludge treatment, landfill leachate treatment, and pathogen removal is also included.
