This paper reviews aspects of the performance of large (>40 ha) constructed treatment wetlands intended for phosphorus control. Thirty-seven such wetlands have been built and have good data records, with a median size of 754 ha. All are successfully removing phosphorus from a variety of waters. Period of record median concentration reductions were 71%, load reductions 0.77 gP¨m´2¨year´1, and rate coefficients 12.5 m¨year´1. Large wetlands have a narrower performance spectrum than the larger group of all sizes. Some systems display startup trends, ranging to several years, likely resulting from antecedent soil and vegetation conditions. There are internal longitudinal gradients in concentration, which vary with lateral position and flow conditions. Accretion in inlet zones may require attention. Concentrations are reduced to plateau values, in the range of about 10-50 mgP¨m´3. Vegetation type has an effect upon performance measures, and its presence facilitates performance. Trends in the performance measures over the history of individual systems display only small changes, with both increases and decreases occurring. Such trends remove little of the variance in behavior. Seasonality is typically weak for steady flow systems, and most variability appears to be stochastic. Stormwater systems display differences between wet and dry season behavior, which appear to be flow-driven. Several models of system performance have been developed, both steady and dynamic.

“…Such low % TP retention of WY2010 was attributed to the flux of soil TP in Cell 1 upon rehydration following the drought event of that year, litter decomposition during vegetation conversion in the southern portion of Cell 2, and SAV decline in Cell 3 (Germain and Pietro, 2011). A detailed summary of P removal performance of STA-2 is presented by Pietro and Ivanoff (2015).…”

“…Another study also found higher N removal in wetland with diverse plant communities than monotypic stands (Weller et al, 2015). Two large-scale CWs in South Florida achieved 77% to 84% of TP reduction over long term operation (Pietro and Ivanoff, 2015). A two-stage VFCW with new media material like rice husks and steel slag removed TN and TP by 100% and 90%, respectively, due to the treatment of aerobic, anoxic and anaerobic conditions in sequences in different heights of the wetland (Zhang, Tan and Peng, 2015).…”

An update on the current research and development of the treatment technologies, which utilize natural processes or passive components in wastewater treatment, is provided in this paper. The main focus is on wetland systems and their applications in wastewater treatment (as an advanced treatment unit or decentralized system), nutrient and pollutant removal (metals, industrial and emerging pollutants including pharmaceutical compounds). A summary of studies involving the effects of vegetation, wetland design and modeling, hybrid and innovative systems, storm water treatment and pathogen removal is also included.
