Title: SULFATE REMOVAL By PHYTOREMEDIATION
Abstract:
One of the low cost treatment of wastewater is Phytoremediation. This has also the advantages of less operational complexity, with low energy consumption and no need for sludge disposal.
In this study, hydroponic plantation was chosen for assessment of two kinds of pervasive swamp plants including pampas grass and bamboo, in sulfate removal. For this reason, the importance of pH factor and determination of detention time, the plants were got into two different distinctive experiments. After determination of the optimum detention time of 7 days, 3 periodic main experiments with 3 repetitions for each concentration were done for the evaluation of removal efficiency and sulfate massive absorption. Statistical T-Test has also been done in the order of 5% significance.
The results indicated the importance of pH in both external efficiency and massive sorption for both plants. Finally, the removal efficiency in pampas grass for all concentrations of 50, 200, 300, 600, 900, 1200, 1500 and 3000 mg/L were 44, 36, 34, 31, 16, 10, 8 and 4 percent, respectively, which were up to 50% more than the one by bamboos. Similarly, in terms of dry weight upon accumulated absorption the best ratio achieved in 600 mg/L which was about 10 for both Pampas grass and Bamboo.
