The aim of this work was to evaluate the removal of Cr(III) and Cr(VI) by Floating Treatment Wetlands (FTW) at microcosm scale. Wetlands were planted with Typha domingensis. The metal distribution in the system water-plants-bottom sediment was also studied. The FTW were designed and constructed in such a way that the roots and rhizomes remain submerged in the water while the aerial parts emerge. The treatments were 5 and 10ppm of Cr(III) and 5 and 10ppm of C(VI). Controls without FTW and without Cr addition were installed.
