Removal of 27 micropollutants by selected wetland macrophytes in hydroponic conditions

Behaviour of 27 selected emerging contaminants in vertical flow constructed wetlands as post-treatment for municipal wastewater

“…If planted, CWs can act via plant uptake of MPs depending on type of plant (Brunhoferova et al, 2021), plant density and plant root amounts. The role of plant uptake is generally known to be combined with those of biodegradation and strongly affected by seasonal variation (Joner and Leyval, 2009;Hijosa-Valsero et al, 2010;Nuel et al, 2018).…”

Fate of Glyphosate and its Metabolite Aminomethylphosponic Acid (Ampa) from Point Source Through Wastewater Sludge and Advanced Treatment

“…The wetlands were planted with Phragmites australis (Verlicchi et al, 2013;Zhang et al, 2017), Lythrum salicaria (Brunhoferova et al, 2021) and Iris pseudacorus (Huang et al, 2018) at a density of 25 plants steams per m 2 . The effluent of the WWTP was pumped to the wetlands as influent and equally distributed along the surface.…”

Bioremediation of 27 Micropollutants by Symbiotic Microorganisms of Wetland Macrophytes

“…The pots were lighted with a LED lamp for hydroponic plants, which included 96 LED chips (32 yellow beads, 32 blue beads, and 32 red beads), and a wavelength of 380-800 nm at 36 watts (Lovebay International Limited, Bristol, England), for 12 h per day. The duration of the experiment was 30 days, with sampling on days 0, 1, 2, 5, 7, 14, and 30 (analogous to our phytoremediation experiment [22]). The volume of each sample was 100 mL.…”

“…Phytoremediation is important in horizontal configurations but is considered negligible for subsurface flow CWs, especially in vertical configurations where the surface exposed to sunlight is limited [21]. Phytoremediation and adsorption have already been targeted in our previous studies [22]. With the knowledge gained from phytoremediation, we could compare and improve our current set-up and assess the efficiency of pure plants for removing MPs.…”
