Abstract: | AbstractPhytoremediation by aquatic macrophytes is a promising technology with higher efficiency and no energy consumption. For this purpose, two macrophytes (Pistia stratiotes, Eichhornia crassipes), and an alga (Oedogonium sp.) were used to treat textile effluents rich in COD, BOD, dyes, and heavy metals (Pb, Fe, Cd, Cu). The aim of the study was to focus on comparative phytoremediation potential of these species by their metal removal capability. During 7?days experiment (day 0–day 6), the results showed that Oedogonium sp. was the best for COD removal and decolorization. Eichhornia crassipes was the best for BOD and heavy metal removal and proves more efficient than Pistia stratiotes and Oedogonium sp. However, Pistia stratiotes was found to accumulate more concentrations of Pb and Fe than Eichhornia stratiotes. |
