“…The significant improvement in the color of wastewater indicated a significant elimination of various pollutants from the wastewater by P. stratiotes. The color elimination capability of P. stratiotes might be attributed to the appropriate particle sedimentation capability of P. stratiotes or the capacity of the root of P. stratiotes to hold together coarse and fine particles 61 .…”

The objective of the study was to evaluate the performance of Pistia stratiotes for treatment of domestic wastewater in a free surface water flow constructed wetland. The objective of the study was to evaluate contaminants removal efficiency of the constructed wetland vegetated with P. stratiotes in treatment of domestic wastewater against Hydraulic retention time (HRT) of 10, 20 and 30 days was investigated. This asks for newer and efficient low-cost nature-based water treatment system which along with cost takes into consideration the sustainability of the ecosystem. Five constructed wetland setups improved the wastewater quality and purify it significantly by reducing the TDS by 83%, TSS by 82%, BOD by 82%, COD by 81%, Chloride by 80%, Sulfate by 77%, NH3 by 84% and Total Oil and Grease by 74%. There was an increase in pH of about 11.9%. Color and odor of wastewater was also improved significantly and effectively. It was observed that 30 days’ HRT was optimum for the treatment of domestic wastewater. The final effluent was found to be suitable as per national environmental quality standards and recycled for watering plants and crop irrigation but not for drinking purposes. The treatment in constructed wetland system was found to be economical, as the cost of construction only was involved and operational and maintenance cost very minimal. Even this research was conducted on the sole purpose of commuting the efficiency of pollutant removal in short span time.

“…The increase of biomass shows that the macrophytes are resistant to the eff ects associated with the uptake of Pb, Cr, Cd, and Hg. The resistance of P. stratiotes and S. molesta to the accumulation of Pb, Cr, and Cd is due to immobilization and sequestration while the ability of P. stratiotes and S. molesta to remove Hg is by phytovolatilization (Garbisu and Alkorta 2001; Ugya et al 2019c). The sediment from the CW also plays a significant role in the heavy metal removal from landfi ll leachates.…”

The current study is aiming to expose the efficiency of surface flow constructed wetland (CW) assisted by Pistia stratiote and Salvinia molesta in the remediation of landfill leachates. A laboratory-scale surface flow constructed wetland was constructed to imitate the characteristic of a natural pond. Composite sample of leachates was collected and transported to the laboratory for further analysis and studies. The removal efficiency of phenol, pesticides, sulphate, chloride, colour, turbidity, total suspend solid (TSS), total dissolved solid (TDS), biological oxygen demand (BOD), chemical oxygen demand (COD), ammonia nitrate and heavy metals (Pb, Cr, Cu, Cd, Ni, Hg)). The removal of heavy metal ions in the CW was determined by using a phyto-system dynamic (phyto-SDA) model while the composite design (CCD) type of response surface methodology (RSM) was employed in this study for the optimization of pesticides and phenol removal from the landfill leachates by the constructed wetland (CW). The study also predicts that the deviation from the linearity between the heavy metals in the leachates and heavy metals in the sediment and in the plant tissues is influenced by the physicochemical status of the leachate and the mixed cultivation of Pistia stratiote and Salvinia molesta. The study reaffirms the role of sediments in the determination of the fate of heavy metals due to its crucial role in the bioavailability of heavy metals for uptake by P. stratiotes and S. molesta in a CW. The study also shows a positive effect of concentration and exposure time on the reduction efficiency of both pesticides and phenol. The result shows that exposure time and concentration of phenol and pesticides are useful in the optimization of the removal efficiency of pesticides and phenol.

“…The content of Ca is concerned with the water movement in the plant parts through the xylem and phloem. Consequently, Ca accumulation is directly correlated to the plant transpiration level (Thor, 2019). A report by Hamzah et al (2012) achieved 92% of Ca removal of palm oil mill after 15 days of phytotreatment using P. stratiotes.…”

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.
