“…Willows have been used for a multitude of environmental applications, such as municipal effluent treatment (Dimitriou and Aronsson, 2011;Guidi Nissim et al, 2015;Hasselgren, 1998;Holm and Heinsoo, 2013;Larsson et al, 2003;Perttu and Kowalik, 1997), biosolids treatment (Dimitriou and Aronsson, 2004), landfill leachate treatment (Aronsson et al, 2010;Dimitriou and Aronsson, 2010), polluted groundwater (Guidi Nissim et al, 2014) and effluent total evapotranspiration Gill, 2014, 2016;Frédette et al, 2019;Gregersen and Brix, 2001) for more than twenty years. In recent years, it has also been shown that the use of willow beds has an interesting potential for the treatment of wastewater (Grebenschykova et al, 2017, Khurelbaatar et al, 2017, complete evapotranspiration of effluent (Frédette et al, 2019) and nutrient recovery (Rastas Amofah et al, 2012) in cold climate. The similarity between willow N, P and K proportional requirements (100:14:72) and the proportion of these nutrients typically found in municipal wastewater (100:18:65) makes the use of SRWC particularly appealing for the treatment of this type of effluent (Perttu, 1993).…”

The objective of this study was to evaluate the treatment efficiency of a short rotation willow coppice (SRWC) vegetation filter for the treatment of wastewater from a municipal primary effluent in a humid continental climate context. The experimental work was carried out at pilot scale on a willow plantation located in Québec, Canada. The experimental design included nine plots that were irrigated with groundwater (L0 = 14 mm/d) or two primary effluents (L1 = 10 and L2 = 16 mm/d) for 111 days. This research showed that SRWCs operated on coarse-textured soils allow efficient removal of organic matter (91 % of COD for L1 and L2) and nitrogen (98 % of TKN for L1 and L2) from wastewater. It was also shown, in this case, that the total nitrogen loading should be used as the limiting design parameter to minimize the risk of contaminating underground drinking water sources with nitrates. Almost complete removal of total phosphorus was observed during this experiment (98 % for L1 and L2). However, a significant increase in soil available phosphorus was observed following the L2 treatment, which suggests an eventual phosphorus soil profile saturation in the event of continued wastewater irrigation. Avoiding such a saturation would require chemical phosphorus removal upstream of SRWC vegetation filters. Finally, an imbalance between irrigation and willows needs was observed as a result of irrigating plots at a constant hydraulic loading rate. Thus, irrigation of an SRWC with wastewater should be modulated according to willow seasonal transpiration trends to allow a better allocation of water and nutrients according to plant needs, and in doing so, increase treatment efficiency and resources valorization. Highlights • Efficient removal of OM and nitrogen (TKN) by coarse textured SRWC vegetation filter • TN should be used as the limiting design parameter of SRWC vegetation filter • Eventual P soil profile saturation in the event of continued wastewater irrigation • Irrigation should be modulated according to willow seasonal transpiration trends

“…The willows will evaporate all wastewater during the growing season, but during winter some wastewater will infiltrate into the soil. Willow systems have recently been piloted in extreme cold climate conditions in Mongolia with promising results (Khurelbaatar et al, 2017).…”

“…However, the design parameters and operation schemes of VSSF TWs must be selected based on the environmental conditions of the site (including climate), the discharge quality, and the characteristics of the influent water [10,14]. Therefore, the implementation of VSSF TWs and their adaptation to new climate conditions (arid, tropical, Mediterranean, boreal) must be assessed, and efforts are underway to better understand the pollutant removal performance, plant selection, and innovative operational schemes [1,[15][16][17]. However, up to now, no performance comparative studies between VSSF TWs of systems operating in two very different climates, such as arid and Mediterranean, or reporting on the use of ornamental flowers have been published.…”

This work compares the performance of vertical subsurface flow treatment wetlands (VSSF TWs) for wastewater treatment, planted with Zantedeschia aethiopica (Za), here operated simultaneously under two different climate conditions, arid and Mediterranean. The experimental setup was divided into two treatment lines for each climate condition: three VSSF TWs planted with Schoenplectus californicus (Sc) (VSSF-S), as the control, and three VSSF TWs planted with Zantedeschia aethiopica (Za) (VSSF-Z), as the experimental unit. The four treatment systems were operated at a hydraulic loading rate of 120 mm/d during spring and summer seasons, in two locations, Iquique (Atacama Desert, Chile) and Talca (Central Valley, Chile). The water quality in effluents, plant development, and water balance were used as performance measures. In terms of the water quality, the influents’ characteristics were similar in both climates and classified as “diluted”. For the effluents, in both climate conditions, average COD and TSS effluent concentrations were below 50 mg/L and 15 mg/L, respectively. In both climate conditions, average TN and TP effluent concentrations were below 40 mg/L and 2 mg/L, respectively. Furthermore, only total nitrogen (TN) and total phosphorus (TP) in effluents to VSSF-Z had a significant effect (p < 0.05) in relation to the climate condition. Regarding plant development, Za showed a lower height growth in both climate conditions, with arid consistently 0.3 m and Mediterranean decreasing from 0.6 m to 0.2 m. However, the physiological conditions of the leaves (measured by chlorophyll content) were not affected during operation time in both climates. Water balance showed that it was not influenced by the climate conditions or plant, with water loss differences below 5%. Therefore, taking into account the water quality and water balance results, Zantedeschia aethiopica can be used in VSSF TWs in a way similar to traditional plants under arid and Mediterranean climates. However, its use has to be carefully considered because lower height could affect the esthetics for its implementation in the VSSF TWs.
