“…Total nitrogen content of duckweed obtained in the study ranged from 30.1 to 61.32 mg N kg -1 dry weight (Table 4). These values compared favourably with the values reported by both Körner & Vermaat (1998) and Vermaat & Hanif (1998). Orthophos-phate-P values measured in the duckweed species used for this study varied from between 0.43 to 2.52 mg kg -1 dry weight (Table 4) were lower than reported values of Körner & Vermaat (1998) and Vermaat & Hanif (1998).…”

The possibility of growing duckweed (Lemna minor) on anaerobic digester effluent and its nitrogen and phosphorus acquisition potential was studied. Duckweed was cultured for 21 days on an anaerobic digester effluent using two methods: static aeration (SAT) and normal batch reactor (NBR) techniques, respectively. The treatments involved pure effluent and 1/10, 1/25 and 1/50 effluent dilutions, respectively. Fifty duckweed fronds were grown in the anaerobic digester effluent for 21 days. At the end of the growth period, phosphate levels, total ammonium nitrogen (TAN) and total oxidized nitrogen (TON) contents of the growth media were determined. Total nitrogen concentration and orthophosphate P content in the duckweed were also determined. The results obtained indicated that duckweed was capable of growing on the anaerobic digester effluent provided its TAN content did not exceed 42 mg N l . The results have demonstrated that duckweed has the potential to recover N and P from anaerobic digester effluent.

“…Since the frond sizes of the three duckweed species vary in the order of S. polyrhiza > L. perpusilla > W. arrhiza, the authors speculated that duckweed species with a larger plant size are likely to be associated with a higher biomass yield under some particular conditions. Vermaat and Hanif made a systematic comparison of the growth of five common European species of duckweed (L. gibba, L. minor, Lemna trisulca, S. polyrhiza and W. arrhiza collected in the surroundings of Delft and Gouda, The Netherlands) on standard mineral growth medium (1/10 Huttner solution) and three types of wastewater (artificial wastewater containing sucrose, acetate and propionic acid; artificial wastewater containing glucose, caseine and vegetable fats; and presettled domestic sewage) [21]. It was found that all five duckweed species produced less biomass on the two artificial wastewaters than on the standard mineral growth medium.…”

“…The removal of phosphorus in the control assay may be due to the growth of microorganisms and algae that utilize phosphorus in their growths, although in small quantities. Vermaat and Hanif [28] conducted several batch growths of macrophytes plants, during 12 days, in domestic wastewater and found that Azolla and Lemna were responsible for about 18% and 56% removal of total phosphorus, respectively. The phosphorus removal rate due to plant uptake was 3.47 mg P m .…”

Over the last decades, phytodepuration has been considered an efficient technology to treat wastewaters. The present study reports a bench scale depuration assay of swine wastewater using Lemna minor. The highest observed growth rate obtained in swine wastewater was 3.1 ± 0.3 gDW m , respectively. The chemical oxygen demand removal efficiency in the swine wastewater assay was 58.9 ± 2.0%. Furthermore, the biomass valorisation by anaerobic co-digestion with swine wastewater was assessed. Results showed a clear improvement in specific methane production rate (around 40%) when compared to mono-substrate anaerobic digestion. The highest methane specific production, 131.0 ± 0.8 mL CH4 g −1 chemical oxygen demand, was obtained with a mixture containing 100 g of duckweed per liter of pre-treated swine wastewater. The water-nutrients-energy nexus approach showed to be promising for swine waste management.
