Adding benefits to phytoremediation of sugar mill effluent by growing water hyacinth (Eichhornia crassipes): Evaluation of biomass for biogas production

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-1d-1), 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 (Ef) and bioaccumulation factor (Bf) 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 (R2= 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 R2 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.

Assessment of plant growth attributes, bioaccumulation, enrichment, and translocation of heavy metals in water lettuce (Pistia stratiotes L.) grown in sugar mill effluent

ABSTRACTThis study was conducted to assess the pollutant uptake capability of water lettuce (Pistia stratiotes L.) in terms of bioaccumulation, enrichment, and translocation of heavy metals grown in sugar mill effluent. Results showed that the maximum fresh weight (328.48 ± 2.04 gm kg−1), total chlorophyll content (2.13 ± 2.03 mg g−1 fwt), and relative growth rate, RGR (11.89 gg−1 d−1) of P. stratiotes were observed at 75% concentration of the sugar mill effluent after 60 days of phytoremediation experiment. The bioaccumulation factor (BF) of different heavy metals was greater than 1 with 50% and 75% concentrations of sugar mill effluent and this indicated that P. stratiotes was hyperaccumulator or phytoremediator of these metals. The enrichment factor (EF < 2 for Cu, Fe, Cr, Pb, Zn, and Mn) and (EF > 2 for Cd) indicated that P. stratiotes mineral enrichment deficient and it moderately enriched the different heavy metals. Moreover, translocation factor (TF) was less than 1 which indicated the low mobility of metals in different parts (root and leaves) of P. stratiotes after phytoremediation. Therefore, P. stratiotes can be used for phytotreatment of sugar mill effluent up to 50% to 75% concentrations and considered as hyperaccumulator aquatic plant for different heavy metals and other pollutants from the contaminated effluents.

Analysis of sugar mill effluent and its influence on germination and growth of African marigold (Tagetes erecta L.)

Sugar industry is a very important agro-based industry in India and it discharges large amount of effluent into water bodies to create high pollution in water bodies which affects the plants and other living organisms. In the present investigation, the physico-chemical analyses of N. P. K. R. Ramaswamy co-operative sugar mill effluent was determined and impact of different concentrations (control, 10, 25, 50, 75 and 100%) of sugar mill effluent on seed germination behavior of African marigold (Tagetes erecta L.) was studied. The morphological parameters such as germination percentage, shoot length, root length, fresh weight and dry weight of seedlings, seed vigour index, tolerance index and percentage of phytotoxicity were calculated. The results recorded for the analyses of sugar mill effluent indicated their some parameters such as PH, EC, acidity, TDS, TS, BOD, COD, sulphate, magnesium, nitrogen, zinc, iron, copper, lead, manganese and oil and grease exceeded the permissible limit compared to Tamil Nadu Pollution Control Board (TNPCB) and then germination and growth parameters increased in lower (10%) concentration of sugar mill effluent and this morphological parameters gradually decreased with increasing effluent concentration. The lower (10%) concentration of sugar mill effluent may be used for irrigation purposes.

The effect of sugar mill effluent on seed germination of green gram (Vigna radiatia L.)

Sugar industry is an agro-based industry in India which released lot of effluent into the environment during sugar production. The formers used this effluent in agriculture for scarcity of water. The effluent contained large amount of organic and inorganic materials which affects the water, soil and living organisms especially plants. The present study was the analysis of sugar mill effluent and different concentrations (10, 25, 50, 75 and 100%) of sugar mill effluent effects on germination and growth development of green gram (Vigna radiata L.). As a result the lower concentration (10%) of sugar mill effluent promoted the germination and growth of the seedlings but higher concentrations of sugar mill effluent inhibited the germination and growth of the green gram seedlings. The lower concentration of effluent contained may be better nutrients of plant which used for irrigation purposed for high growth and yield.

Effects of Treated Sugar Mill Effluent Irrigation on Soil and Hybrid Cultivar of Eggplant (Solanum melongena L.) under Field Conditions

The disposal of sugar mill effluent is a major problem in India due to generation of huge quantity of effluent in the sugar mills. The present investigation was conducted to study the effects of sugar mill effluent as an alternative of synthetic fertilizers. Six plots were selected for six treatments of sugar mill effluent viz. 0% (control), 20%, 40%, 60%, 80% and 100% for irrigation of Solanum melongena L., cv. Pusa Purple Long Hybrid-F 1 . The S. melongena was grown in sugar mill effluent irrigated soil till harvest and effects of sugar mill effluent on the soil and agronomical characteristics of S. melongena were analyzed. The concentrations of sugar mill effluent produced significant (P Mn>Cd>Cu>Fe>Cr for the soil and Fe>Mn>Cu>Zn>Cd>Cr for S. melongena in both seasons after irrigation with sugar mill effluent. Thus, sugar mill effluent irrigation increased nutrients in the soil and affected the growth of S. melongena in both seasons. Consequently, it can be used for irrigation in the lower proportion (up to 60%) to improve the yield of S. melongena.

Sugar Mill Effluent Utilization in the Cultivation of Maize (Zea mays L.) in Two Seasons

The aim of present investigation is to study the effects of sugar mill effluent fertigation on soil properties and agronomical characteristics of Maize (Zea mays L. cv. NMH 589) in two seasons. Six treatments of sugar mill effluent, namely, 0% (control), 20%, 40%, 60%, 80%, and 100%, were used for the cultivation of Z. mays. Fertigation with different concentrations of sugar mill effluent resulted in significant (P&lt;0.01) changes in EC, pH, OC, Na+, K+, Ca2+, Mg2+, TKN, PO43-, SO42-, Fe3+, Zn2+, Cd2+, Cu2+, Mn2+, and Cr3+ of the soil in both seasons. The maximum agronomic performance of Z. mays was noted with 40% concentration of sugar mill effluent. Biochemical components like crude proteins, crude fiber, and total carbohydrates were recorded highest with 40% concentration of sugar mill effluent in both seasons. The contamination factor (Cf) of various heavy metals was observed in order of Mn2+&gt;Zn2+&gt;Cu2+&gt;Cd2+&gt;Cr3+ for soil and Mn2+&gt;Zn2+&gt;Cu2+&gt;Cr3+&gt;Cd2+ for Z. mays in both seasons after fertigation with sugar mill effluent. It appears that sugar mill effluent can be used as a biofertigant after appropriate dilution to improve the yield.
