Combined efficacy of Azadirachta indica and Moringa oleifera leaves extract as a potential coagulant in ground water treatment

Azadirachta indica and Moringa oleifera plants have been reported to have strong prospective in the improvement of physiological and chemical parameters of water however very few studies have been reported towards investigating the potential of combinatorial treatment of plant extracts in water treatment. Therefore in this study, we have tried to investigate the efficacy of combined treatment of Azadirachta indica and Moringa oleifera leaves extract in hexane on ground water. We have used Jar apparatus test (flocculator) to evaluate the purification potential of combined plant extracts treatment on physiological and chemical parameter of ground water in a dose dependent manner. Our experimental findings have strongly proven the better potential of combined extract on different water quality parameters including pH (8.4–7.1), total dissolved solids (525–201), total hardness (253–127), turbidity (15.70–5.10), fluoride content (2.80–1.00), and Escherichia coli count (325–30) in comparison to individual extracts of Azadirachta indica and Moringa oleifera leaves extract at the similar doses (0, 25, 50, and 100 mg/L). Therefore combinatorial treatment could be a strong alternate to the individual extracts in water purification.
