| dc.description.abstract | The present study was done in order to use various bio-coagulants for the removal of water pollutants from pulp and paper industry wastewater. Different bio-coagulants were prepared from various plant spp. such as Opuntia sp., Agave americana and Moringa oleifera by drying and subsequent grinding. Initial concentrations of various parameters in the pulp and paper industry wastewater were analyzed to determine the pollutants characteristics in wastewater. The prepared bio-coagulants were used to remove water pollutants that include BOD, COD, sodium, potassium and chloride present in the wastewater sample. Waste water treatment was carried out using different dosages of all theabove prepared bio-coagulants (2g, 4g, 6g, 8g and 10g) in 1 litre of the wastewater sample at three different contact times (60 min, 90 min and 120 min). Maximum adsorption was recorded using bio-coagulants at 10g dosages L-1 of the sample at 120 min contact time. It was found that all the bio-coagulants have almost higher removal efficiency for water pollutants as compared to the chemical (alum) coagulant. The removal efficiencies of various pollutant levels were also analyzed statistically by using regression analysis. Based on the results obtained, it may noted that use of such bio-coagulants is a cost effective, ecofriendly, and more efficientmethod for the removal of water pollutants from pulp and paper industry wastewater. | en_US |
