Around the world, water has always been a mysterious element. Designated as a natural drink, it is and remains a major constituent of our body. Aware that thousands of people do not have access to drinking water, this study aims to develop an organic suspension, extract of Moringa oleifera seeds capable of clarifying and partially disinfecting turbid and contaminated water intended for consumption. The study method initially consisted in collecting plant drugs in order to produce a suspension (extract of seed of Moringa oleifera). Secondly to study the physico-chemical (clarifying) properties followed by a microbiological (bacteriological) study before and after application of this suspension at different concentrations on crude water samples meticulously sampled from some wells in Parakou city. The experimental results have shown a strong improvement in the physico-chemical parameters involved, in particular color, turbidity and conductivity with clarification rates of 84.33% for color and 87.58% for turbidity; followed by a considerable reduction in the bacterial flora estimated at 66.46% of the total Coliforms; 81.19% of mesophilic aerobic germs; 77.78% of Escherichia coli, then a total elimination of faecal Streptococci with 100% and Staphylococcus aureus with 100%, thus confirming the improvement in the organoleptic and sanitary quality of drinking water by extracts of seeds of Moringa oleifera.
