“…El transporte de oxígeno por medio de la vegetación a la rizósfera favorece los puntos de oxigenación adyacentes a la zona radicular y origina el proceso de nitrificación (Ye & Li, 2009). La presencia de vegetación dentro de los humedales promueve la eliminación de nutrientes, al disminuir la velocidad del flujo y aumentar la carga hidráulica, y reducir la resuspensión de los sedimentos (Laterra, Booman, Picone, Videla, & Orúe, 2018). De la misma forma, la aireación intermitente favorece la nitrificación y desnitrificación (Llyas & Masih, 2017).…”

El tratamiento de aguas residuales por medio de los humedales artificiales se utiliza como una tecnología verde que surge de la necesidad de replicar los beneficios ecosistémicos de los humedales naturales para tratar diversos afluentes de aguas residuales. Este trabajo presenta una revisión bibliográfica acerca de los diferentes tipos de humedales artificiales y sus procesos depurativos. Si bien existen muchos estudios sobre humedales artificiales, es necesario realizar una sinergia de dicha información. No obstante, aunque los humedales artificiales son una frecuente práctica de gestión para la mitigación de contaminantes provenientes de escorrentía agrícola y municipal, en muchos países faltan estudios comparativos sobre su eficiencia depurativa y el mantenimiento a los mismos, así como profundizar en la investigación de sustratos alternativos y detallar medidas preventivas para la evitar la colmatación del sustrato.

“…In contrast with the relatively well‐known influence of macrophytes on the nutrient dynamics of lentic water systems (Laterra et al, 2018), the role of macrophytes in riverine nutrient dynamics is still poorly known and offer contradictory results (Clarke, 2002; recently reviewed in García et al, 2017). For example, Moore et al (2010) observed lower P‐SRP loads in vegetated than in nonvegetated agricultural drainage ditches in the United States, whereas a minor role of macrophytes for nutrient removal has been found in Pampean streams (García et al, 2017).…”

In agricultural basins, fluvial ecosystems can work as filters when retaining the nutrient excess from agricultural activities, mitigating the impacts downstream. In frequently flooded areas, like the Pampas Region of Argentina, natural streams are being channelized to reduce flood frequency and intensity, thus increasing land suitability for crop production, but the impact of these interventions on nutrient removal capacity by streams is unknown. To evaluate the effects of channelizing streams on the assimilation rate of nitrate, ammonia, and phosphorus, nutrient addition experiments were performed in streams of the southern Pampas under three different conditions: (i) channelized reaches without Schoenoplectus californicus (C.A. Mey.) Palla (reeds), (ii) unchannelized reaches without reeds, and (iii) unchannelized reaches with reeds. Assimilation rates were estimated by applying the one-dimensional transport with inflow and storage (OTIS) model, which considers the solute transport with lateral flow and storage. Nitrate and ammonia uptake rates were higher in unchannelized than in channelized stream reaches, and a higher nitrate assimilation rate was found in the presence of reeds, indicating an important role of this macrophyte in the nitrate uptake. In the case of phosphorous, uptake rates were higher in unchannelized reaches with reeds than in the channelized reaches. These results suggest that channelizing first-order streams in agricultural landscapes of the Argentine Pampas may significantly reduce the ability of streams to mitigate nutrients loss to continental and marine water sinks.

“…Also, Parwin and Karar Paul (2019) observed the most reduction of EC was 63.71% while for TDS it was 63.71% after 4 weeks of the phytoremediation of the kitchen wastewater using E. crassipes. Similarly, Ugya et al ( 2019) achieved a premier decline of EC by 84.90% during the phytoremediation of dyeing wastewater using water lettuce, while Laterra et al (2018) and Kinidi and Salleh (2017) achieved TDS reductions of 70%-82.50% during the treatment of dyeing wastewater using water lettuce.…”

The present study describes the phytoremediation performance of water lettuce (Pistia stratiotes L.) for physicochemical pollutants elimination from paper mill effluent (PME). For this, pot (glass aquarium) experiments were conducted using 0% (BWW: borewell water), 25%, 50%, 75%, and 100% treatments of PME under natural day/light regime. Results of the experiments showed that the highest removal of pH (10.75%), electrical conductivity (EC: 63.82%), total dissolved solids (TDS: 71.20%) biological oxygen demand (BOD: 85.03%), chemical oxygen demand (COD: 80.46%), total Kjeldahl's nitrogen (TKN: 93.03%), phosphorus (P: 85.56%), sodium (Na: 91.89%), potassium (K: 84.04%), calcium (Ca: 84.75%), and magnesium (Mg: 83.62%), most probable number (MPN: 77.63%), and standard plate count (SPC: 74.43%) was noted in 75% treatment of PME after treatment by P. stratiotes. PCA showed the best vector length for TKN, Na, and Ca. The maximum plant growth parameters including, total fresh biomass (81.30 ± 0.28 g), chlorophyll content (3.67 ± 0.05 mg g −1 f.wt), and relative growth rate (0.0051 gg −1 d −1 ) was also measured in 75% PME treatment after phytoremediation experiments. The findings of this study make useful insight into the biological management of PME through plant-based pollutant eradication while leftover biomass may be used as a feedstock for low-cost bioenergy production. © 2021 Water Environment Federation • Practitioner points• Biological treatment of paper mill effluent using water lettuce is presented.• Best reduction of physicochemical and microbiological pollutants was attained in 75% treatment. • Maximum production of chlorophyll, plant biomass, and highest growth rate was also observed in 75% treatment.
