Clarification of pond water by moringa oleifera almond powder for drip irrigation

In arid and semi-arid areas, where water is a imitating factor, the agriculturals use other system of irrigation especially the drip to drip one for the agricultural production. The ground water particularly the pool waters employed are generally trouble and limit the working device of drip to drip irrigation due to clogging of the drippers. The aim of this study is to test the kernel powder of Oleifera Moringa for the pool water clarification in order to improve the durability of drip to drip system of irrigation. The pool waters of Kongou Gorou Zarmadandey is located in North-East at 7km of Niamey in Niger has been taken away for the treatment. The latter found on coagulation-flocculation with a recipient -test consists in applying the kernel powder of Oleifera Moringa respectively dried at three temperatures ( 25, 40 and 50° C) and applied by three doses ( 50, 100 and 150 mg, l-1). ). The parameter sized up is essentially the turbidity of water. The results has showed that the application of kernel powder of Oleifera Moringa clarified significantly the pool water especially from 30 minutes of decantation. In fact, the initial turbidity of the unrefined water (638 NTU) lowered significantly by 74, 99 and 99% respectively with the dose of 50, 100 and 150 mg / l of oleifera M. after 24 hours of decantation. The diminution of turbidity by oleifera M. is significantly higher with the doses of 100 and 150 mg / l than with the dose of 50 ml / l. The dose of 100 mg / l oleifera M. seems to be the optimal dose for the clarification of Kongou Gorou Zarmagandey pool waters. However, an additional works can be consider for studying the impact of oleifera M. kernel powder on the chemical and bacteriological quality of pool waters.
