“…Reprinted with permission from Headley and Tanner (2012). Headley and Tanner (2012) provide a comprehensive review of the available floating treatment wetland performance data, including mass removal rates and areal k-rates. Although data from long-term, full-scale applications are somewhat limited, data from mesocosm and pilot studies indicate that floating treatment wetlands can significantly improve the performance of pond systems and provide similar or better performance than surface flow wetlands for removal of organic matter, suspended solids, nutrients and metals.…”

“…• Water supply reservoirs A floating treatment wetland consists of emergent wetland vegetation growing on a mat or structure that floats on the surface of a pond-like water body (Headley and Tanner, 2012). The plant stems remain primarily above the water surface, while their roots grow down through the buoyant structure and hang in the water column (Figure 8.4).…”

Stormwater Treatment Evaluation of a Constructed Floating Wetland after Two Years Operation in an Urban Catchment

Constructed Floating Wetlands (CFW) for stormwater treatment are increasingly used to treat urban runoff. However, studies of large-scale systems and the long-term evaluation of their treatment efficiency are scarce. This article presents the final results of a two-year study of the pollutant removal performance of a CFW in a stormwater pond capturing runoff from a low-residential catchment in South-East Queensland (Australia) under subtropical conditions. Although the CFW treatment area to catchment ratio was only 0.14%, the results demonstrated a significant removal of both Total Suspended Solids (TSS) and Total Phosphorus (TP) from the stormwater inflows by the CFW. The efficiency ratios for TSS and TP were 81% and 52%, respectively. While the removal rate for total nitrogen was not significant for the CFW evaluated in this study, the ER was still 17%. However, the ERs for nitrate and nitrogen oxide were both 47%. The study results suggest that it may be possible to increase the pollution removal performance of the CFW by upsizing the system and including intermittent re-aeration zones in the surrounding stormwater pond. The results of this research study clearly demonstrate that CFW can be an effective treatment solution for the removal of pollution from urban stormwater runoff.

Floating treatment wetland (FTW) systems are an innovative stormwater treatment technology currently being trialled in Australia. FTWs provide support for selected plant species to remove pollutants from stormwater discharged into a storage basin. The plant roots provide large surface areas for biofilm growth, which serves to trap suspended particles and enable the biological uptake of nutrients. FTWs can be installed at the start of the construction phase and can therefore start treating construction runoff almost immediately. FTWs have the potential to provide a full range of stormwater runoff treatment (e.g. sediment and nutrient removal) from the construction phase onwards. A 101 m 2 FTWs has been installed within a greenfield development site on the Sunshine Coast, in Australia. The two-year research study investigated the pollution removal performance of the FTW for two different locations, one with low and one with moderate influent pollutant concentrations. This paper presents the research methodology used, and the initial study results of the treatment efficiency of FTWs.
