Treatment of textile effluents with and .

Phytoremediation by aquatic macrophytes is a promising technology with higher efficiency and no energy consumption. For this purpose, two macrophytes (, ), and an alga (.) 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 . was the best for COD removal and decolorization was the best for BOD and heavy metal removal and proves more efficient than and . However, was found to accumulate more concentrations of Pb and Fe than .
