“…Some works on constructed wetlands (CW) supported the involvement of the substrate in the element removal. The unplanted CW showed higher efficiency in removing the heavy metals compared to the CW units planted with macrophyte [29,[38][39][40]. Net of copper found in the leaves, most of the element was probably accumulated at the root level and hypothetically onto perlite.…”

In Mediterranean countries, the use of copper-based fungicides in agriculture is causing a concerning accumulation of copper in the upper layer (0–20 cm) of soils and water bodies. Phytoremediation by energy crops offers the chance to associate the recovering of polluted environments with the production of biomass for bioenergy purposes. The purpose of this work was to evaluate the morpho-physiological response of giant reed (Arundo donax L.), a well-known energy crop, when treated with increasing concentrations of Cu (0, 150, and 300 ppm) in a semi-hydroponic growing system (mesocosm) for one month. The plant morphology (height and base diameter of the stem, number of stems) was not affected by the treatments. The presence of Cu led to the disequilibrium of Fe and Zn foliar concentration and caused an impairment of photosynthetic parameters: at 150 and 300 ppm the chlorophyll content and the ETR were significantly lower than the control. The study demonstrated that, although the presence of Cu may initially affect the plant physiology, the Arundo plants can tolerate up to 300 ppm of Cu without any adverse effect on biomass production, even when grown in semi-hydroponic conditions.

“…A further study also revealed the efficiency of this method by using Thalia dealbata, Acorus calamus, Zizania latifolia and Iris sibirica for river water treatment [19,20]. Marchand et al [21] effectively applied this technology (combined with a homogeneous mix of gravels and perlite) for the removal of copper ion from synthetic Cu-contaminated wastewaters using Phragmites australis, Juncus articulates and Phalaris arundinacea. In addition, the vegetated system using Typha sp.…”

Constructed wetland applications have been limited by a large land requirement and capital investment. This study aimed to improve a shallow pond water hyacinth system by incorporating the advantages of engineered attached microbial growth technique (termed Bio-hedge) for on-site domestic wastewater treatment. A laboratory scale continuous-flow system consists of the mesh type matrix providing an additional biofilm surface area of 54 m 2 /m 3 . Following one year of experimentation, the process showed more stability and enhanced performance in removing organic matter and nutrients, compared to traditional water hyacinth (by lowering 33%-67% HRT) and facultative (by lowering 92%-96% HRT) ponds. The wastewater exposed plants revealed a relative growth rate of 1.15% per day, and no anatomical deformities were observed. Plant nutrient level averaged 27 ± 1.7 and 44 ± 2.3 mg N/g dry weight, and 5 ± 1.4 & 9±1.2 mg P/g dry weight in roots and shoots, respectively. Microorganisms immobilized on Bio-hedge media (4.06 × 10 7 cfu/cm 2 ) and plant roots (3.12 × 10 4 cfu/cm) were isolated and identified (a total of 23 strains). The capital cost was pre-estimated for 1 m 3 /d wastewater at 78 US$/m 3 inflow and 465 US$/kg BOD5 removed. This process is a suitable ecotechnology due to improved biofilm formation, reduced footprint, energy savings, and increased quality effluent. OPEN ACCESSWater 2015, 7 330

“…Although precipitation of insoluble sulfides is evidently the main removal mechanism of Cu and Zn, the accumulation of metals in wetland plants ( Phragmites australis ) has to be taken into the account as the additional mechanism of the metals removal . Furthermore, sorption sites provided by the substrate in the wetland and those related to the bacterial biofilm can play the significant role in the heavy metals removal in constructed wetlands as well . The constructed wetland with a horizontal subsurface flow can be successfully used in order to remove Cu and Zn from municipal wastewater.…”

Removal of selected metals from municipal wastewater using a constructed wetland with a horizontal subsurface flow was studied. The objective of the work was to determine the efficiency of Cu, Zn, Ni, Co, Sr, Li, and Rb removal, and to describe the main removal mechanisms. The highest removal efficiencies were attained for zinc and copper (89.8 and 81.5%, respectively). It is apparently due to the precipitation of insoluble sulfides (ZnS, CuS) in the vegetation bed where the sulfate reduction takes place. Significantly lower removal efficiencies (43.9, 27.7, and 21.5%) were observed for Li, Sr, and Rb, respectively. Rather, low removal efficiencies were also attained for Ni and Co (39.8 and 20.9%). However, the concentrations of these metals in treated water were significantly lower compared to Cu and Zn (e.g., 2.8 ± 0.5 and 1.7 ± 0.3 μg/l for Ni at the inflow and outflow from the wetland compared to 27.6 ± 12.0 and 5.1 ± 4.7 μg/l obtained for Cu, respectively). The main perspective of the constructed wetland is the removal of toxic heavy metals forming insoluble compounds depositing in the wetland bed. Metal uptake occurs preferentially in wetland sediments and is closely associated with the chemism of sulfur and iron.
