Pollutant Removal Efficiency

The water framework directive (CEC, 2000) asks for cost-effective measures for achieving good ecological conditions in receiving waters. Because of low operation costs and good pollutant removal efficiency, vortex separators (VS) are an attractive alternative to traditional stormwater tanks. The German design standard for CSO structures, ATV-A 128 (1992), demands long-term pollution load simulations. Today's simulation software, however, considers the removal processes in CSO structures either very rudimentarily or not at all. The higher pollutant removal efficiency of a structure like a VS cannot be taken into account. This might be one reason why VS are used still comparatively scarcely. A mathematical model describing the removal efficiency could increase the acceptance of VS. Several functions describing the removal efficiency have been derived from model tests or large-scale studies within the last few years. Within this paper, the data from three large-scale studies are used to verify the general applicability of one steady-state and one dynamic approach. The results show that the complex processes involved with CSO facilities and the large error related to monitoring make the validation of models a difficult task. Anyhow, especially the dynamic approach was applicable at all considered facilities.

Heavy Metals And Arsenic

In this study, Phragmites australis (common reed) was transplanted into solutions added with different concentrations of Mn, Zn, Cd, Pb, and As for 30 days in the laboratory (10 days of incubation and repeated three times without changing the plant) to assess the removal of these metals and its accumulation in the plant. The results showed that high removal efficiency was achieved by growing P.australis. The highest daily removal rates of heavy metals and As were obtained after 1 day of new solution addition. The highest concentrations of Mn, Zn, Cd, Pb, and As in the plant roots were 3920, 1020, 90.9, 1350, and 183 mg kg–1 dry wt., respectively; those in the stems were 465, 108, 26.4, 227, and 74.0 mg kg–1 dry wt.; and those in the leaves were 716, 150, 18.1, 157, and 88.3 mg kg–1 dry wt. The results of this study indicated that P. australis has the ability to remove simultaneously these metals from water, making it a potential species for phytoremediation of wastewater from Pb-Zn mine.
