“…As a result, the treated wastewater met the zero level concentration of bacteria according to the WHO/FEPA standard for the discharge of wastewater into surface water. Similar results were reported previously by researchers (Aisien et al 2010b ;De-Busk and Reddy 1987 ;Dar et al 2011 ). The effi ciency of reduction of all the water quality indicators investigated using the water hyacinth ( Eichhornia crassipes ), water spinach ( Ipomoea aquatica ) and mixed algae ( Chlorella vulgaris and Closterium turgidum ) in the different treatment stages revealed the order of water hyacinth > water spinach > mixed algae.…”

“…In previous studies Eichhornia crassipes (Shah et al, 2010;Schneider et al, 1995;Dar et al, 2011), Pistia stratiotes (Rodrigues et al, 2017;Lu et al, 2011) and Spirodela polyrhiza (Ansal et al, 2010;Li et al, 2017) showed their potentials in phytoremediation of wastewater. In a 2017 review article Mishra and Maiti elaborately discussed the previous findings on the pollutant removal characteristics of Eichhornia crassipes (Mishra and Maiti, 2017).…”

Textile wastewater contains large quantities of organic and inorganic compounds, which cause toxic and hazardous pollutants in the environment. Efficacy, efficiency and feasibility of the biological treatment method using macrophytes and algae were investigated, and various physicochemical parameters (TSS, TDS, pH, color, EC, DO, BOD, COD and metal concentration) were also analyzed. In pre-treated sample, TSS, TDS, pH, temperature, DO, BOD, COD, EC and color were recorded as 913 mg/L, 2250 mg/L, 9.4, 41°C, 2.84 mg/L, 358 mg/L, 721 mg/L, 1555 μS/cm and 1347 TCU respectively. As, Cr, Pb and Cu (heavy metals) were observed exceeding the limit stipulated by WHO. COD and the pH reduction was effective in biological treatment with aquatic plants, algae and their combination, but not significant for color removal. Eichhornia treatment found most effective in reducing BOD, COD, TDS and TSS. Mixed treatment reduced the pH from 9.4 to 7.5. Both macrophytes and algae exhibited appreciable heavy metal uptake tendency, but Eichhornia crassipes was identified as the most effective in heavy metal removal because of its extensive root system. An Eichhornia based adsorbent was prepared for removal of color from the wastewater and found to be capable of removing 58% of the color. The investigation erected pathway towards phytoremediation of polluted surface water in lakes and rivers, too.

“…Kumar et al (2017a) reported that the water hyacinth (E. crassipes) has potentially treated the paper effluent and it can be used for the elimination of nitrogen, phosphorus, calcium, magnesium and parameters as MPN and SPC of the effluent. Dar et al (2011) Table 2). The less reduction in the minimal concentration of sugar mill effluent may be subjected to the bioavailability of the net metal content in the medium as already discussed in our previous study .…”

In this experiment, we assessed the phytoremediation potential of water hyacinth (Eichhornia crassipes) for pollutants removal from sugar mill effluent amended at different concentrations and further biogas production from its grown biomass co-digested with cow dung in a laboratory scale anaerobic digester. The results showed that the maximum values of kinetic growth rate (2.56gg), total chlorophyll content (4.10±0.10mg/gfwt.) and fresh plant biomass (393.87±4.67g/Kg) of E. crassipes were achieved in 75% concentration of sugar mill effluent after 60 days of phytoremediation experiments. Also, the enrichment factor (E f ) and bioaccumulation factor (B f ) of heavy metals were greater than or equal to 1 in the roots and leaves of E. crassipes which indicated efficient elimination of these metals from the sugar mill effluent.Significant values of cumulative biogas production (5195 ml) and predicted by modified Gompertz kinetic model (5238.71 ml) were found after 15 days of anaerobic digestion at 40°C with maximum reduction of COD (83.11%) of the substrate slurry. The plot of log(COD) vs. t (HRT) suggested good fitness of first order kinetic equation (R 2 = 0.9746) for reduction of co-substrate COD. The different kinetic parameters of COD reduction for biogas production viz., a , xc and k were noted as 6096.12, 7.73 and 0.26, with R 2 value of 0.99, respectively. The findings of this study concluded that E. crassipes can be used for the phytoremediation of heavy metals and other pollutants most efficiently in 75% concentration of the sugar mill effluent.Additionally, the biomass of E. crassipes grown during phytoremediation can be used for enhanced biogas production.
