“…Sandhi and co-authors (2018) reported that the As concentration in W. fluitans increased with increasing As concentration [ 6 ], as found also in other studied species [ 32 ]. The relationship between the internal and external concentrations was linear, at least up to the 100 mM arsenate (As(V)) treatment: in our case we used arsenite (As(III)) and this is the possible reason why the uptake was irrelevant.…”

“…Phytofiltration capacity of an aquatic moss for application in polluted water remediation as a bio-filter, has only started to be investigated moving research to further its value as bioindicator [ 6 ]. It was shown that the aquatic moss, Warnstorfia fluitans took up As from water accumulating up to 4.5 mg of As per g of dry weight (DW) without influencing its biomass [ 6 ]. The moss accumulated high levels of As similar to those found in As-hyperaccumulating fern, Pteris vittata , which accumulated 3.5 mg As per g DW in its fronds without any sign of toxic effects [ 6 , 27 ].…”

“…Drepanocladus spp. [ 5 ] and Warnstorfia fluitans appeared particularly efficient in the uptake of arsenic [ 6 ]. Funaria hygrometrica accumulates great quantities of lead [ 7 ] but less than 10 species are known for the accumulation of various HMs [ 8 ].…”

Heavy metals (HMs) are released into the environment by many human activities and persist in water even after remediation. The efficient filtration of solubilized HMs is extremely difficult. Phytoremediation appears a convenient tool to remove HMs from polluted water, but it is limited by the choice of plants able to adapt to filtration of polluted water in terms of space and physiological needs. Biomasses are often preferred. Aquatic moss biomasses, thanks to gametophyte characteristics, can act as live filtering material. The potential for phytoremediation of Hypnales aquatic mosses has been poorly investigated compared to aquatic macrophytes. Their potential is usually indicated as a tool for bioindication and environmental monitoring more than for pollutant removal. When phytoremediation has been considered, insufficient attention has been paid to the adaptability of biomasses to different needs. In this study the heavy metal uptake of moss Taxiphyllum barbieri grown in two different light conditions, was tested with high concentrations of elements such as Pb, Cd, Zn, Cu, As, and Cr. This moss produces dense mats with few culture needs. The experimental design confirmed the capacity of the moss to accumulate HMs accordingly to their physiology and then demonstrated that a significant proportion of HMs was accumulated within a few hours. In addition to the biosorption effect, an evident contribution of the active simplistic mass can be evidenced. These reports of HM accumulation within short time intervals, show how this moss is particularly suitable as an adaptable bio-filter, representing a new opportunity for water eco-sustainable remediation.

“…Hou, Guo, and Wen (2018) studied sulfate and sulfide removal rates in CWs treating water resource recovery facility secondary effluents with varying sulfate loads and found that an increase in the sulfate loading (1.42-7.01 g S/m 3 day) rate increases sulfate removal (1.42-3.16 g S/m 3 day) and sulfide discharging rates (0.08-1.46 g S/m 3 day). Sandhi, Landberg, and Greger (2018) investigated the phytofiltration performance of an aquatic moss (Warnstorfia fluitans) originating from arsenic (As)-contaminated wetlands with varying concentrations of arsenic (1, 10, and 100 μM of arsenate), nutrient loading (0%, 1%, and 10% Hoagland nutrient solution), removal times (0 to 192 hr) along with the adsorption/absorption mechanism of living and dead moss, where 82% removal was observed within 1 hr of operation with 1 μM As and no nutrient in the water. However, a HSSFCW treating acid mine drainage(AMD) containing As-rich acidic waters in the presence and absence of P. australis and two different filter media setups (zeolite and limestone) showed removal rates of As and Pb (>99%), Fe (>98%), and Zn (23%-75%, depending on the cell type (Lizama-Allende, Jaque, Ayala, Montes-Atenas, & .…”

This article presents an update on the research and practical demonstration of wetland treatment technologies for wastewater treatment. Applications of wetlands in wastewater treatment (as an advanced treatment unit or a decentralized system) and stormwater management or treatment for nutrient and pollutant removal (metals, industrial and emerging pollutants including pharmaceutical compounds and pathogens) are highlighted. A summary of studies involving the effects of vegetation, wetland design and operation, and configurations for efficient treatment of various municipal and industrial wastewaters is also included.
