Constructed Floating Wetlands (CFW) are artificial systems that mimic the water treatment processes that take place in natural floating wetland islands. CFW are constructed using buoyant matting materials made from a variety of recycled waste products. This structure is then fitted with emergent macrophytes which occur in natural wetlands. The roots of these macrophytes are submerged in the water and provide a large surface area for biofilm attachment. The biofilm adsorbs pollutants while physically filtering and trapping suspended solids.
This study will monitor and compare the water treatment performance of two CFW systems and investigate how well the CFW in both locations are working under static conditions, throughout changing seasons, and how well they are able to treat potential stormwater runoff entering the body of water.
The results of this study should provide valuable information on how well CFW perform in urbanised areas, and whether they will be able to manage the volumes of stormwater runoff, and the pollution loads entering the system.
