| dc.description.abstract | The present study was done in order to use various natural coagulants and algae culture for the removal of water pollutants from wastewater. Natural coagulants were prepared from bark of plant spp. such as Eucalyptus grandis (Eucalyptus) and Melia azedarach (Bakain or Pride of India) by drying and subsequent grinding. Initial concentrations of various parameters in the wastewater were analyzed to determine the pollutants characteristics in wastewater. The prepared natural coagulants were used to remove water pollutants that include BOD, COD, Pb and Cu present in the wastewater sample. The wastewater was found with higher BOD and COD value of about 230 mg/l and 1000 mg/l respectively. Pb and Cu content were found in wastewater of about 0.942 mg/l and 0.145 mg/l respectively. Wastewater treatment was carried out using different dosages of all the above prepared natural coagulants (1gm, 2gm and 5gm) and algae culture (1 ml, 2 ml, 5 ml) separately at three different retention times (24 HRT, 48 HRT and 72 HRT). Maximum removal efficiency was recorded using natural coagulants at 5gm dosages per liter of the sample at 72hrs retention time. The maximum pollutant removal efficiency in percentage for BOD, COD, Pb and Cu was found to be 91.30, 91.00, 91.61 and 91.03 respectively. Further, it has been observed that the natural coagulants had higher removal efficiency for water pollutants as compared to the algae so it may conclude that natural coagulants may be used as a sustainable and environmentally friendly solution for remediation of wastewater. | en_US |
